 than thorax; face, mandibles and base of scape beneath pale yellowish; tips 

 of antenna? blackish; pleura with dense silvery pubescence ; metathorax ru- 

 gulose, posterior face depressed and transversely aciculated; wings hyaline, 

 with a dusky band beneath stigma; posterior tibiae blackish at tips, their tarsi 

 pale; abdomen black, smooth and polished. Length .18 inch. 



One specimen. (Coll. G. W. Belfrage.) 



Gonatopus? alatns, n. sp. 



9- — Pale ferruginous, head shining, much broader than thorax, trans- 

 versely compressed; front flat; eyes large, prominent, ovate; clypeus trans- 

 verse, subconvex, bituberculate at tips; occiput concave: apical margin of 

 clypeus, mandibles and scape beneath, whitish; antennas slender, as long as 

 head and thorax, 10-jointed, first joint short and robust, second small, scarcely 

 half the length of first, third very long and slender, more than twice the 

 length of first and second together, black, scape and two or three apieal joints 

 yellowish; prothorax elongate, as long as metathorax, convex, subtruncate an- 

 teriorly, narrowed and somewhat constricted posteriorly ; mesothorax short, 

 convex, fusco-ferruginous ; metathorax elongate, rounded behind, longitudi- 

 nally rugose at base above; wings narrow, scarcely reaching tips of posterior fe- 

 mora, fuscous, with a large rounded hyaline spot beneath base of stigma 

 nearly as broad as the wing; legs rather paler than body, anterior pair very

 chelate; four posterior legs much shorter than anterior pair, all the femora 

 much thickened toward base; abdomen elongate, smooth and shining. Length 

 .23 inch. 



Two specimens. (Belfrage.) I have with doubt referred this re- 

 markable insect to the genus Gonatopus, from which it differs by the 

 more elongate slender form and by having wings.
