KO. 2219. A REVISION Of THE VREMASTINI—CUSHMAN. 505 



Genus PSEUDERIPTERNUS Viereck. 



Pseuderipternus Viereck, Conn. State Geol. and Nat. Hiat. Survey Bull. 22, p. 269 



Genotype. — Podogasier radiolata Provancher (Monobasic). 



Since its description in Podogastor, tho genotype has been placed 

 in Limnermm by Cresson,* who considered Podogasier a synonym of 

 Limnerium; in Eripiernus by Ashmead,^ under the manuscript name 

 primus Ashmead; in tho last genus by Viereck,^ where lie used it 

 as a basis for comparison of his genus EriptemimorpTm. with Eripter- 

 nus; and more recently Viereck has erected for it tho present genus, 

 which he treats as a subgenus of Casinaria, a Campoplegino genus. 



To tho present wiuter the placing of the genus in the Campoplegini 

 seems entirely erroneous. In Ci'esson's synopsis it runs to Cremastus 

 Gravenhorst by virtue of its separated clypeus, a character in which 

 it differs markedly from the Campoplegini. Its completely areolated 

 propodeum is also out of place in the latter tribe. In Szepligeti's 

 key to the genus * it runs to Pseudocremastus Szepligeti. From 

 Cremastus and from Dolichoselephus Ashmead it differs principally 

 in the characters used in the above table to genera, the most striking 

 of which are the nearly middle position of the spiracles of the first 

 abdominal segment, the gi'eat length of the areola, the very narrow 

 stigma accompanied by the distally originating radius, and the long, 

 narrow, very obtusely angled radial cell. 



From DolicTioselepJius it also differs in having the palpi normal. 



From the description of Pseudocremastus it differs principally in 

 the very low propodeum. 



From Eripiernus (Foerstor) Szepligeti it differs by the characters 

 used by Szepligeti in his group synopsis and by nearly all the char- 

 acters in his generic description of Eripiernus. 



Head st ongly transverse, romidly narrowed posteriorly, occipital 

 carina broadly interrupted in middle, eyes slightly convergent below 

 face convex, clypeus narrow and strongly convex, clypcal foveae 

 deep, malar space very short, ocelh in both sexes small, antennae 

 long, filiform, the flagellar joints gradually decreasing in length 

 from base to apex where they are nearly as wide as long, palpi normal, 

 thorax long, subcylindrical, nearly straight above, notauli very 

 weak, propodeum elongate, low, prolonged about one-third length 

 of coxae, completely areolated, even the posterior abscissa of lateral 

 carina being more or less distinctly present, areola occupying half 

 or more of the length and the potiolar area very short, spiracle 

 nearer to lateral than to pleural carina ; front wings with stigma and 

 radial coll elongate, tho former with tho radius arising far beyond 

 middle, hind wings with median vein obliterated basally, nervollus
