SOME NOTES ON WASPS OF THE SUBFAMILY NYSSONI-NAE, WITH DESCRIPTIONS OF NEW SPECIES.
By S. A. Rohwee,Custodian of Uymenoptera, United States National Museum.
This paper contains, besides the descriptions of a few new species,notes on some of the genera of the wasps of the subfamily Nyssoninae.In the definition of the subfamily the characterization given in theclassification presented in the Hymenoptera of Connecticut * hasbeen followed. The treatment here suggested differs, however,from that published in 1916 in that it places the Spheciini in the sub-family Nyssoninae. The thoracic characters of this group, as well asthe venation, indicate that the genus Sphecius is more closely alliedto other members of the subfamily Nyssoninae than to those of thesubfamily Stizinae, where it was placed in the Connecticut Hymen-optera. Why this error in the placing of the genus Sphecius wasmade is hard to explain, but on the face of it one would be justifiedin saying the author neglected to study the insect and just blindlyfollowed previous "systems."In some few members of this subfamily the defining suture orcarina of the prepectus is feeble, and while it is impossible to saythat the use of this character will be entirely reliable, the groupingsobtained by it are on the whole natural and deserving of furtherstudy. In Ammatomus Spinola the prepectus is practically want-ing yet it is evidently a member of the tribe Gorytini. In TricMogo-rytes Rohwer the dorsal part of the prepectal suture is obliteratedand because of the presence of a suture below the tubercle it seemsto be present between the tubercle and tegula. The rest of the bodyis typically that of the tribe Gorytini, where it undoubtedly belongs.Besides the character of the prepectus members of this subfamilyhave the following characters in common: Basal vein joining thesubcosta close to the stigma (not its length or more basad as in theBembecidae); basal lobe of the hind wings small; middle tibiawith two calcaria; intermediate coxae well separated.

;
stigma small Nyssonini.Mesopleura with a dorsal plate (poorly denned in Ammatomus and present onlyposteriorly in Sphecius); dorsal angles of propodeum not dentate 2
.
2. Pronotum long, subequal in length with the scutellum; suture between the meso-and meta-pleura angulate so the metapleura is wider above; second cubital cellperiolate; stigma large Alysonini.Pronotum short, normal; suture between the meso- and mata-pleura straight sothat part of the metapleura is nearly parallel sided ; second cubital cell sessile. .3.3. Stigma very small; no suture from below tegula to prepectus; sternauli want-ing Spheciini.Stigma large, well developed 4.4. Sternauli well defined Hoplisini.Sternauli wanting Gorytini.Tribe NYSSONINI.Genus NYSSON Latreille.For the time being, and until the species from other regions canbe studied, it seems best to consider the various North Americangroups of Nyssonini as subgenera. That this will be the final or morelogical arrangement is, however, to be doubted, because the differ-ences between Zanysson and Nysson are of greater importance thanthe differences between Nysson and Brachystegus. The subgenusFoxia is also distinctly limited and may be a genus.Key to the North American Subgenera of Nysson.1. Metanotum bilobed ; hind tibiae serrate on their outer margin; cubitella arisingwell beyond end of anallen cell; apical tergite of male usually with four or moreteeth Zanysson, new subgenus.Metanotum not bilobed 2.2. Hind tibiae serrate on their outer margins; first intercubitus wanting; both recur-rents joining the first cubical cell Metanysson Ashmead.Hind tibiae not serrate on their outer margins, at most spinose 3.3. Second recurrent joining the third cubital cell; sides of apical tergites armed withspinelike protuberances; cubitella arising well beyond the end of anallencell Foxia Ashmead.Both recurrents joining the second cubital cell; apical tergites without spinelikeprotuberances 4.4. Cubitella arising before or nearly interstitial with nervellus Nysson Latreille.Cubitella arising far beyond nervellus 5.5. Third intercubitus present Brachystegus A.

Turner considersGuerin's genus to be the same as Ilelioryctes Smith and makes itthe type genus of a subfamily containing ZoypMum Kohl, Serico-phorus Smith, and Splwdrotes Kohl. The subfamily Paranyssoninaeis not closely allied to Nysson, and it is evident that the group ofNorth American species which Cresson assigned to Paranysson needsa new name. As none of the synonyms of Nysson are available, Ipropose the name Zanysson for Paranysson Cresson, not Guerin.In the bilobed metanotum this subgenus differs from all othergroups of Nysson, and it may later be desirable to consider the groupof generic value. The male of Metanysson has not been described,but from the other North American 3 groups the male of Zanyssoncan easily be distinguished by the greater number of teeth on theapical tergite. The venation of Zanysson is the same as Brachystegus.Key to North American species of subgenus Zanysson.Besides the species here treated there are in the National Collectionmales, which appear to represent three other species, but inasmuchas they are not associated with females and there is some doubt asto the value of the number of teeth on the apical tergite it seems bestto leave them undescribed until more material is available.1. Legs black fuscipes (Cresson).Legs largely ferrugineous 2.2. Males 3.Females 5.3. Third antennal joint but little shorter than the fourth; apical tergite very coarselysculptured as is also the last; median teeth of apical tergite large and close to thelateral ones; fourth tergite with a yellow spot aureobalteatus (Cameron).Third antennal joint not more than half as long as fourth 4.4.

This change permits the inclusion of the genus ArpactusJurine and certain species of Hoplisoides which would otherwise beexcluded.At least in some cases the convergence of the eyes toward theclypeus is a secondary sexual character.Key to the North American Genera.

I have not seen the genotype and they may bo correct, but it seems doubtful inasmuch as thespecies, other than the genotype, which were originally assigned to the genus, do not agree with bipunctatus,the genotype of Paramellinus.
