J. — Ferruginous, with pale glittering pubescence; head much broader 

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

 of antennfe blackish; pleura with dense silvery pubescence; metathorax ru- 

 gulose, posterior face depressed and transversely aeiculated ; 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? alatus, 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; antennae slender, as long as 

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

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

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

 long, coxae and trochanters as long as femora which are longer than tibiae, tarsi 

 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.
