TEXAN HYMENOPTERA. 159 



Cryptus sororius, n. sp. 



%. — Differs from calipterus as follows: — Thorax shorter, more robust and 

 more gibbous; head broader, face shorter, median swelling more prominent; 

 antennae with a yellow, not well defined, annulus about the middle; areolet of 

 anterior wing more pentagonal than quadrangular ; posterior wings yellow, with 

 apex only fuscous; legs and abdomen more robust, first segment of latter much 

 broader at apex; ovipositor shorter, the sheaths concolorous with abdomen. 

 Length .47 inch. 



Two specimens. (Belfrage.) Easily distinguished from calipterus 

 by the more robust form, by the shape of areolet and by the color of 

 posterior wing and sheaths of ovipositor. 



C'ryptus bnccatus, n. sp. 



9- — Differs from calipterus 9 as follows: — Head broader than thorax, sub- 

 quadrate, cheeks swollen; clypeus flat and very transverse, apex truncate; 

 mandibles pointed, not bifid; antennae shorter and more robust, with joints 

 short and compact, joints 8 — 11 lemon-yellow above ; metathorax scarcely trun- 

 cate behind, with lateral carina subobsolete ; areolet smaller, 5-angular ; pos- 

 terior wing yellow, with apex and posterior margin fuliginous; posterior tibia? 

 not black at tips ; first abdominal segment gradually, not suddenly, dilated to 

 apex; sheaths of ovipositor pale fulvous. Length .50 — .58 inch. 



% . — Differ from calipterus % as follows: — Head larger and buecate ; antenna? 

 black, with a fulvous annulus beyond middle; the triangular yellow spot 

 beyond stigma on anterior wing much reduced; posterior wing yellow only at 

 base and on costal margin; legs darker in color, posterior femora and tibia? 

 uniformly reddish-brown, the latter with a yellowish sericeous pile; tarsi lute- 

 ous, with fuscous incisures, terminal joint rufous; abdomen shorter, more 

 robust and subclavate, apex more or less blackish. Length .55 inch. 



Several % 9 specimens. (Belfrage.) Easily distinguished fro n 

 either of the preceding species by the large, subquadrate head, swollen 

 cheeks and short, more robust antennae. 



C'ryptus comalensis, n. sp. 



9 . — Head and thorax dull ferruginous, opaque, abdomen paler; minutely 

 sculptured; antenna? blackish above, with a rather broad yellowish annulus 

 about the middle; metathorax abrupt behind, the posterior face transversely 

 rugose, above finely sculptured, with two transverse, sinuate, rather indistinct 

 carina?; wings dark fuscous, slightly violaceous, areolet rather small, 5-angu- 

 lar; legs ferruginous, tarsi paler, coxa? and trochanters fuscous; first ab- 

 dominal segment smooth and shining, apex broadly dilated, with prominent 

 lateral tubercles; basal margin of second segment narrowly black, the third 

 with a black band occupying the basal fourth of the segment; ovipositor about 

 one- half the length of abdomen, piceous, sheaths ferruginous. Length .50 

 inch.
