NATIONAL MUSEUM Vol.92 Washington: 1942 No. 3137DESCKIPTIONS OF FIVE NEW SPECIES OF CHALCIDOI-DEA, WITH NOTES ON A FEW DESCRIBED SPECIES(HYMENOPTERA) By a. B. Gahan This paper contains descriptions of three new species of Brachy-meria, (one from Panama, one from Mexico, and one from Java), anew species of Blepyrus from Louisiana, and a new species of Ooencyr-tus from Wyoming. All are described from reared material. Thehost record for the Ooencyrtus is especially interesting, since thespecies is parasitic in eggs of the Mormon cricket. Synonymicaland distributional notes for a few described species also are included.Family CHALCIDIDAEGenus BRACHYMERIA WestwoodBRACHYMERIA JAMBOLANA, new speciesTumidicoxoides jambolana (Girault, MS.)

Ramakrishna Ayyar published the Girault manuscript nameTumidicoxoides jatnbolana without description, listing the species asa parasite of Carea suhtilis at Counbatore, India. Subsequently herepublished the parasite record, this time listing the parasite asTumidicoxoides n. sp. Girault. So far as known the name has neverbeen validated. The specimens that formed the basis for the Giraultmanuscript name are in the United States National Museum andrepresent part of the material used for the present description. Thegenus Timiidicoxoides was reduced to synonym}^ with (Jhalcis by423982?42 41 42 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 92Girault,^ but Chalcis of authors (not Fabricius), as now recognized, isBrachymeria Westwood, and it is in that genus that the speciesbelongs.Female.?Length 4.25 mm.

Also very similar to alhotibalis Ashmead from which it dif-fers by having the tooth nearest the base of posterior femur smalleror at least no larger than some of the other teeth, by having the punc-tures on mesoscutum and scutellum more narrowly separated, by hav-ing the pits on hypopygiimi somewhat smaller and m.ore numerous,by having the flagellar joints very slightly shorter, and by havingthe blackish band at base of posterior tibia shorter, this band usuallyembracing only about one-sixth the length of tibia.Postorbital branch of the genal carina present and well developed ; punctures of thoracic dorsum coarse and contiguous; apex of scutel-lum with the plate weakly emarginate medially ; propodeum coarsely,irregularly rugose; abdomen subacute, ovate; first dorsal segment ofgaster smooth and nearly bare dorsally but with the dorsolateralangles conspicuousl}^ hairy; following segments weakly shagreenedwith one or more conspicuous rows of hairs extending clear acrossthe dorsum, the penultimate segment with moderately strong pitsin addition to the shagreening; hind femur with rather weak, finepunctures, more or less shining, its ventral margin with 10 to 12blunt teeth, the 3 teeth nearest base usually shorter than the otherspostmarginal vein fully twice as long as stigmal vein.Black; flagellum dark brown or black; palpi, tegulae, apical halfof anterior femur, apical one-third of median femur, a large spot atapex of hind femur, anterior and median tibiae entirely, and all tarsiyellow; hind tibia yellow, with a narrow black or blackish band atextreme base and the carina along the margin black.

No. 20898.Remarks.?The type and two paratypes, according to the labeling,were reared at Coimbatore, India, June 1, 1916, from a moth infesting "Jambolana." Since these specimens are the original Girault manu-script types, they are undoubtedly the specimens upon which Ayyar's 1 Ins. Insclt. Menstr., vol. 14, p. 66, 1926. NEW CHALCIDOIDEA?GAHAN 43 record, cited in the synonymy, was based. According to this note thehost was Carea svhfAUs (Walker) infesting Eugenia jambolan-a. Twoadditional paratypes from Coimbatore are labeled "Par. on Danals,14-11, 1913, Ponniah coll." Six paratypes are from Buitenzorg,Java, reared in March 1932 from pupae of Papillo agamemnonLinnaeus, and six others from the same locality were reared froma lepidopterous pupa on Ficus ampelas^ April 1, 1935, by Dr. Muller.Four paratypes (two of which were returned to the sender) werereceived in 1939 from C. J. H. Franssen, of the Institute for PlantDiseases, Buitenzorg, Java, reared in June 1936 from Papilio aga-memnon by R. Awibowo. Five additional paratypes from Padang,Sumatra, were reared from P. ago/memnon and received in 1918 fromS. Leefmans. BRACHYMERIA DISCRETA, new speciesThis species differs from all the previously described species ofBrachymeria known to me by having on the dorsum of the scutellujna conspicuous, smooth, impunctate area that is slightly elevated androunded posteriorly and terminates rather abruptly a little behind themiddle of the scuteilum. The species superficially resembles B.fonsGolombei Dufour but may be distinguished by the longer andslenderer antenna, by the much shorter teeth on the hind femur, bythe broadly arcuate emargination of the second segment of the gaster,by the conspicuous smooth area on the scuteilum, and by the somewhatdifferently colored legs.Female.?Length 4.75 mm. Antennae inserted on a line with lowerextremities of eyes; scape rather long; flagellum moderately slender,nearly the same thickness throughout most of its length, the twoapical joints of club tapere,d to a blunt point; first funicular jointabout twice as long as broad, second and third funicular joints alittle longer than broad, fourth to seventh joints quadrate or nearlyso; club very slightly longer than the two preceding joints. Ocell-ocular line distinctly a little more than half the longest diameterof a lateral ocellus. Head rugosely sculptured, the rugosity some-what coarser laterad of the upper half of scrobe than elsewhere; post-orbital branch of genal carina present and complete; malar spaceless than half the eye height. Thorax punctate, the punctures onprescutum distinctly larger than those on scapulae; punctures onscuteilum similar to those on posterior part of prescutum; carinateplate at apex of scuteilum narrow and not emarginate; propodeumirregularly rugose, without well defined carinately bounded areasexcept adjacent to the spiracles; mesopleuron with femoral depres-sion strongly transversely striated. Forewing with postmarginal veinabout one-fourth as long as marginal ; stigmal vein completely sessileand hardly half as long as postmarginal. Posterior femur nearlytwice as long as broad, its outer surface closely punctate, its ventral 44 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 92margin with about 9 or 10 miiisiially short, bkmt, subeqiial teeth andwith a slight tubercle on inner ventral margin.

BRACHYMERIA DISCRETOroEA. new speciesThis is very similar to di^ereta but, so far as may be judged by thematerial at hand, seems to be sufficiently distinct to justify descriptionas a different species. NEW CHALCIDOIDEA?GAHAN 45Female and male.?Both sexes differ from ducreta in the follow-ing particulars: The ocellocular line is less than half as long as thelongest diameter of a lateral ocellus. The vertex is a little lessstrongly sculptured and when viewed from directly above seems tohave a low but distinct ridge originating at the dorsal margin of themedian ocellus and rumiing laterad in front of each lateral ocellusnearly to the eye margin, where it curves downward along the innerorbit. (No such ridge is apparent in discreta.) The slightly ele-vated area is present on the scutellum but in this species is vei*y finelysculptured. The femoral depression on the mesopleuron is not trans-versely striated but smooth. The propodeum is divided by coarsecarinae or rugae into about 25 more or less distinct areas, the medianone of which is ovate or elliptical in shape and extends from the baseto the apex of the propodeum, while the others are irregular in shapeand roughly arranged in series of three between the base and the apexof the propodeum. The stigmal vein is not completely sessile but veryshortly petiolate. The color is very similar to that of discreta.Anterior coxae black, middle pair ahnost entirely, and posteriorpair beneath reddish testaceous; trochanters testaceous; anterior andmiddle femora blackish with their apices pale yellowish ; hind femurmostly black with the base broadly testaceous and a large pale-yellowspot at apex; anterior and middle tibiae yellow at bases and apices,dark testaceous to blackish in the middle; posterior tibia black atextreme base, with a large yellow spot near base and another at apex,the rest reddish testaceous; tarsi testaceous; forewings very faintlytinged with fuscous; abdomen of female reddish beneath, of maleentirely black. In all other respects agreeing with description ofdiscreta.Type localiti/.?Frijoles, Panama Canal Zone.Type.?V.BI^M.

(New synonymy.)To the already long list of synonyms of this widely distributedspecies, as set forth by Kurdjumov in 1913 and amplified by Gahan in 46 PROCEEDINGS OF THE NATIONAL MUSEUM vol.921938, apparently should be added Trichomalus trujilloi Blanchard.Blanchard described tnijilloi as a parasite of the oriental fruit moth inUruguay.H. L. Parker recently sent to the Bureau of Entomology and PlantQuarantine specimens that he stated were bred from this moth atMontevideo, Uruguay, by Mesa Carrion, and that had been identifiedas Trichomalus trujilloi by Blanchard. Parker recognized the Uru-guayan parasite as probably Dihrachys cavus and requested that theybe compared with material of that species in Washington. So far asI can see these specimens do not differ in any respect from Dihrachyscavus, and since they also agree perfectly with the description ofTrichomalus trujilloi I have no hesitation in declaring the latter namea synonym. Genus HYPSICAMARA FoeisterHYPSICAMARA LACHNI (Ashmead), new combinationPachpcrepis lacJmi Ashmead, Traas. Amer. Eut. Sue, vol. 14, p. 193, 1887.The types of Pachycrepis lachni Ashmead, which are in the UnitedStates National IVIuseum collection, do not have complete parapsidalgrooves and therefore do not belong in the genus Pachycrepis. Theparapsidal grooves are present only on the anterior one-half of theinesonotum. In this respect, as well as in all other generic characters,this species seems to agree with Hypsicamara Foerster as representedby H. ratzehmgi, the genotype, of which I have seen specimens in theNaturhistorisches Museum in Vienna, Austria, identified by GustavMayr.Hypsicamara is very similar to Pacltynejiron Walker, differing onlyby having a slightly longer and slenderer marginal vein, which,although distinctly thickened, is nearly uniform in width throughoutits AA'hole length, and by having the abd; men in both sexes sub-cylindrical and distinctly narrower than the thorax. The genus mayhave to be synonymized with Pachyneuron e\ entually.Ashmeacl's types of Hypsicobinara lachni were reared from a pineai)hid {Lachrms austraJis Ashmead) at Jacksonville, Fla.I have recently identified as H. lachiii the following material re-ceived from Clyde F. Smith, of Ohio State University, and rearedby him in connection with an investigation of the parasites of variousaphids : 3 specimens reared fi'om aphids on Pinus mrginiana collectedin Hocking County, Ohio, June 2G, 1938; 19 specimens from aphidson Salix, Columbus, Ohio, June 19 and July 7, 1938 ; 5 specimens froman unidentified host collected at Mink Creek, Idaho, July 18, 1937 ; and6 specimens taken at Beaver Creek, Utah, July 25, 1937. Still morerecently 6 specimens of what appears to be the same species werereceived through O. Peck, reared July 1, 1932, from aphids on Ahieslyalsamea, taken at Fredericton, New Brunswick, Canada, by K. E.Balch.

(Newsynon.ymy. ) The types of Ahlerus perspeciosus Girault and Azotus silvestriiCompere in the United States National Museum collection have beencompared and found to agree completely. A. pert^peciosus was de-scribed from specimens reared from Diaspis pentagona Targioni takenat Nishigahara, Japan, and A. silvestni from specimens supposedlyreared from Chrysomphalus aonidum (Linnaeus) taken at Shanghai,China.Two specimens, determined by Girault as Ahlenis perspiciosits, arein the United States National Museum collection, reared from Diaspispentagona at Washington, D. C, in October 1913 by R. A. Cushman.One specimen, also now in the National Museum collection, was re-cently received from W. J. Schoene, of the Virginia AgriculturalExperimental Station at Blacksburg, Va., wlio stated that it had beenreared from D. pentagona but did not indicate the exact locality wherethe scale was taken. Family ENCYRTIDAEGenus BLEPYRUS HowardBLEPYRUS SACCHARICOLA, new speciesThis species differs from typical Blepyrus in some respects. Thefrons is distinctly narrower than in B. insularis (Cameron), the ocellartriangle is acute, and the sculpture of the mesoscutum and scutellumis distinctly finer and more granulose. In other respects the femalediffers only slightly from insularis. The antenna of the male, how-ever, is quite unlike that described for insularis by Timberlake.- Ac-cording to Timberlake the funicle in the male of insularis has onlythree joints and the club is very greatly enlarged and solid. In thepresent species the male antenna has six distinct funicular joints anda club that is only slightly thicker than the last funicular joint, sub-cylindrical, obliquely truncate at apex, and distinctly 3-jointed. Themale antenna somewhat resembles that in Zarhopalu^, but the vena-tion is different, and the scape of the female is not distinctly expanded.The species is also similar to Euryrhopalus in many respects but differsin the shape of the head, in the longer marginal vein, and in theantenna of the male.

Mus., vol. 21, p. 237, 1898.Synaspidia Timbeklakb, Proc. Hawaiian Ent. Soc, vol. 5, p. 397, 1024. (Newsynonymy. ) The type of EuTyrho])dlus schwarzi Howard (genotype of Euryrho-palus) and paratypes of Synaspidia pretiosa Timberlake (genotypeof SynasTndia) have been compared and found to agree in all genericcharacters. The two species are extremely similar but may be dis-tinguished, for the present at least, by the fact that schioarzi is slightlythe larger, with the forewing distinctly infumated behind the mar-ginal vein, the hind wing distinctly more than half as broad as theforewing and forming a broad but distinctly acute angle at its apex,while the forewing of pretiosa is without distinct infuscation and thehind wing is not more than half the width of the forewing with itsapex more rounded. Otherv/ise they seem to be practically in-distinguishable. Genus OOENCYRTUS AshmeadOOENCYRTUS ANABRIVORUS, new speciesThe female of this species is usually, though not always, brachyp-terous. The fully winged female appears to be a nearly typicalOoeiicyrtiis except that the scutellum is less strongly sculptured, lessconvex, and less rounded at apex, while the forewing is weakly in-fuscated medially and the abdomen is a little longer and more robustthan usual. The brachypterous females have the scutellum nearly fiat,very faintly sculptured, and subacute posteriorly, while the wingsvary in length and correspondingly in width, in some specimensbarely extending to the apex of the propodeum, but in others attain-ing the middle of the abdomen. In the majority of individuals the 50 PROCEEDINGS OF THE NATIONAL IVrUSEUM vol. 92forewings extend to or a little beyond the apex of tlie first tergite. Themales apparently are always fully winged but differ from typicalOoencyrtus by having the funicle of the antenna slightly compressed,the joints subequal, about as broad as long, narrower at base than atapex and clothed with relatively short liairs, none of which is longerthan the segments. These differences do not seem sufficient to justifythe erection of a new genus for the species, the habits of which agreewith those of other species of Ooencyrtus.Fully winged female.?Length 1.6 mm. Head as wide as thorax,with fine, reticulate sculpture ; eyes rather large, very sparsely pilose ; ocelli small, forming a nearly right-angle dtriangle; ocellocular lineslightly longer than diameter of lateral ocellus; width of frons equalto approximately one-third width of head ; frontovertex about one andone-third times as long as broad; scrobes moderately impressed,romided above ; cheeks rounded ; malar groove distinct but fine ; mandi-bles each with three short subequal teeth; maxillary palpus four-jointed, labial palpus 3-jointed; antennae inserted near anterior mar-gin of face ; scape compressed, about four times as long as broad, broad-est medially; pedicel subcylindrical, nearly three times as long asbroad, about equal in length to first and second funicular segmentscombined ; funicular joints cylindrical or nearly so, the first joint just alittle longer than broad and slightly narrower than pedicel; secondjoint subequal to first; third to sixth joints about as long as broad, thesixth slightly thicker than the first; club cylindrical, not thicker thanfunicle, about as long as three preceding funicular joints combined anddistinctly 3-jointed. Thorax slightly compressed dorsoventrally ; mesoscutum distinctly broader than long, weakly convex, weakly re-ticulated and with numerous small, shallow hair punctures; scutellumlow, nearly flat, subtriangular, subacute at apex, a little longer thanmesoscutum and with similar reticulate sculpture, but with sparserand less distinct hair punctures; whole dorsum of thorax somewhatshining; propodeum short, weakly reticulately sculptured, withoutdistinct carinae; pleura more strongly sculptured and less shiningthan mesoscutum. Legs normal, spur of middle tibia about two-thirdsas long as first tarsal joint. Forewing extending beyond apex ofabdomen, a little more than twice as long as broad ; marginal vein alittle longer than broad, postmarginal longer than marginal but alittle shorter than stigmal, which is about twice as long as marginalmarginal cilia short; discal cilia rather dense and short; obliquehairless streak behind stigmal vein wider posteriorly than anteriorlyand complete.
