1. Fimpla maura, n. sp. — 9- — Black, supojiaque ; dot on tip of scape beneath, 

 spot on scutellum, sub-obsolete line on postseutelluni.and anterior legs in front, 

 whitish ; wings dark fuscous, nervures and stigma black, the latter pale at base ; 

 antcnnce brown-black. Form robust ; head and thorax rather finely punctured, 

 face rugosely so ; metathorax transversely rugose ; abdomen robust, segments 

 short and transverse, densely and coarsely punctured, extreme apical margins 

 smooth; excavated base of first segment smooth and polished ; ovipositor much 

 shorter than abdomen, robust, sheaths finely pilose. Length Ci lines. 



Ilab. — Texas. This is our largest and most robust species, and 

 easily distinguished by the color, both of body and legs, being almost 

 entirely' black. 



2. Pimpla atrocoxalis, n. sp. — 9- — Head, thorax, abdomen, coxas and tro- 

 chanters entirely black ; rest of legs yellowish-red ; wings subhyaline, tinged 

 more strongly with fuliginous toward apex; (antennse wanting). Form sub- 

 robust, very densely punctured, the punctures more coarse on abdomen ; pos- 

 terior femora robust; abdomen subfusiform, seventh segment less densely and 

 coarsely punctured than the others and shining. Length 5i lines. 



Ilab. — Hudson's Lay Territory. Keadily known by the reddish 

 legs, with all the coxae atid trochanters black. 



4. Pimpla texana, n. spi — 9- — Black, head and thorax shining; clypeus 

 ;ind mandibles dark rufous; a white spot between eye and base of mandible ; 

 antennse brown-black, slander; mesothorax, scutellum and pleura smooth and 

 j)olished ; metathorax sub-truncate behind, with a carina on each side, meeting 

 above and forming a small conical cell on the disk ; wings uniformily fusco- 

 hyaline, nervure black, stigma brown, areolet rhomboidal ; legs, including all 

 the eoxre, rufous, posterior tibice and tarsi black ; abdomen with upper surface 

 not impressed, finely granulated, with a silky gloss. Length 4 lines. 



Ilab. — Tfixas. Very distinct from jjedalis by the dark wings and 

 finely granulated abdomen. 



7. Pimpla aquilonia, n. sp. — %. — Black, head and thorax shining; meta- 

 thorax and abdomen with a short, rather dense, pale sericeous pile; antenna; 

 slender, testaceous, scape fuscous ; tegulse and spot on scutellum, white ; meta- 

 thorax smooth and rounded; wings hyaline, iridescent, stigma and veins 

 brown-black, former pale at base, areolet rhomboidal; legs yellowish-rod, an- 

 terior coxce paler, posterior tibiae black, with a rather broad white annulus, 

 their tarsi blackish, the joints slightly paler at base; abdomen narrow, slightly 

 broader towards apex, opaque, very densely and minutely punctured. Length 

 3i lines. 



Ilab. — Maine. Differs from tenukornis by the shape and sculpture 

 of the abdomen, which in the latter species is narrowed towards apex, 

 the segments constricted at base, the surface densely and coarsely 

 punctured, with the apical margin smooth and polished; while in 

 aquilonia the surface is even, entirely punctured and very minutely so.
