DESCRIPTIONS OF NEW REARED PARASITIC HYMEN-OPTERA AND SOME NOTES OF SYNONYMY By C. F. W. MuESEBECKOf the Bureau of Entomology, United States Department of Agriculture In addition to the descriptions of 14 new species of Hymenopterabelonging to the family Braconidae, this paper contains synonymicalnotes involving certain of Provancher's species of the braconid sub-family INIicrogasterinae. All of the new species are described fromreared material, and all but three from specimens reared at the gii-'symoth laboratory of the Bureau of Entomology at Melrose Highlands,Mass. The notes on synonymy are the result of a recent examinationof the types of Provancher's species of Microgasterinae, which are inthe Museum of Public Instruction, in the Parliament Building, atQuebec, Canada.Superfamily ICHNEUMONOIDEAFamily BRACONIDAESubfamily VipiinaeMICROBRACON HELIANTHI, new speciesMost similar to pi7ii Muesebeck, but at once separated by the black-ish wings, the mostly red thorax, the entirely red abdomen, the ab-sence of a distinct stub of a median longitudinal carina toward ape.xof propodeum, and the slightly longer ovipositor sheaths.Female.?Length, 3 mm. Head long antero-posteriorly, polished;frons completely smooth and shining; diameter of opening betweenclypeus and mandibles about twice as long as the malar space;antennae 34-segmented, all the flagellar segments longer than broad,but not even the first twice as long as broad ; thorax robust; mesoscu-tum smooth and polished, the lobes not at all prominent, the parapsi-dal grooves not distinctly impressed; furrow in front of scutellumfine, straight, finely foveolate; scutellum large, polished; propodeumentirely smooth and polished, without a distinct stub of a medianNo. 2633.?Proceedings U.

METEORUS CINGILIAE, new speciesFalls between hypliantriae Riley and datanae Muesebeck, beingmost similar to the latter, sometimes separable only with difficulty.It appears, however, to be a good species. It can usually be dis-tinguished from datanae by the somewhat coarser reticulation ofthe propodeum, the finer punctation of the narrower median lobeof mesoscutum, the more polished, impunctate scutellum, and themuch paler stigma. The posterior tibiae are entirely yellowwhile in datanae there is a distinct blackish annulus near base ; and ' the apical fifth is black.Female.?Length, 4.5 mm.

ART. 7 NEW PARASITIC HYMENOPTERA MUESEBECK 5A study of the types shows conclusively that trachynotus andfemur-nigrum are identical. The species is known only from themale sex, but appears to be common throughout northeastern UnitedStates and southeastern Canada. The female may have been de-scribed under another name, but if so, it must differ considerablyfrom the male. APANTELES CARPATUS (Say)Microgaster carpata Say, Boston Journ. Nat. Hist., vol. 1, 1836, p. 263.Microgaster clavatus Provancher, Natural. Canad., vol. 12, 1881, p. 196.Apanteles clavatus Provancher, Addit. faun. Canad.

Mus., vol. 58, 1920, p. 517.The type of clavatus is in poor condition, but, in my opinion, iscarpatus (Say). The name clavatus then must fall as a synonymof carpatus, rather than replace polychrosidis as I previously (1920)suggested. APANTELES LATERALIS (Provancher)Microgaster lateralis Provancher, Addit. faun. Canad. Hymen., 1886, p.141.Apanteles consimilis Viereck, Proc. U. S.

Mus., vol. 61, 1922, p. 42.Although the abdomen and antennae of the type of lateralis aremissing, the unusual nature of the sculpturing on the propodeumand the minute characteristics of the venation of the anterior wingin the vicinity of the second cubital cell are strikingly in agreementwith those characters in consimilis; furthermore, Provancher's de-scription of the abdomen agrees with abdomen of conshnilis. I amconvinced that the latter name must fall as a synonym of lateralis.APANTELES LONGICORNIS (Provancher)Microgaster longicomis Provancher, Addit. faun. Canad.

Mus., vol. 58, 1920p. 570. 6 PROCEEDINGS OP THE NATIONAL MUSEUM vol. 69Apparently all that remains of Packard's type series of two speci-mens is a fore wing mounted on a tag in the Museum of Compara-tive Zoology, at Cambridge. Mass. Recently, however, Dr. T. H.Frison, of the University of Illinois, sent me some specimens of anApanteles which he had reared at Champaign, 111., from Vitulaed7na.nsii, the same host from which Packard's cotypes were ob-tained. He suggested that his specimens might be Packard's neph-opteHcis^ and a comparison with the characteristic type wing andwith the original description leaves no doubt that this is the case.The identity of this species is thus established. Furthermore, Doc-tor Frison's material, in my opinion, is identical with the cotypesof Apanteles ephestiae Baker, making it necessary to suppress thatname. The hosts of the types of both nephoptericis and ephestiaewere found feeding on honeycomb ; consequently it is not surprisingthat the should belong to the same species.APANTELES PTEROPHORI, new speciesA very distinct species, although somewhat resembling fwrniferanaeViereck. From the latter it differs strikingly in the absence of thepropodeal areola, in the much smoother second abdominal tergiteand the much shorter ovipsitor.Female.?Length 2.7 mm.

It also resembles somewhat depressus Viereckand pyralidis Muesebeck, but is more elongate, with a narrower, moreparallel-sided first tergite, and with a less transverse second tergite.From euchaetis Ashmead, which it resembles in habit, and in itscocoons, it differs especially in the distinctly shorter posterior tibialspurs, the more parallel-sided first tergite and the less polishedscutellum.Fei)iale.?Length, 2.3 mm.

It canreadily be distinguished from that Si3ecies, however, by the muchmore strongly punctate mesoscutum and scutellum and by the moreslender female antennae.
