Type.— Cat. No. 25976, U.S.N.M. 



One male taken June 7, 1915, by E. P. Van Duzee. 



HYPOPHELTES, new genus. 



In the structure of clypeus and frons, longitudinally impressed 

 mesopleura, venation of the wings, and compressed abdomen this 

 genus resembles Opheltes; while in the simple claws, broadly sepa- 

 rated glymmae and receding temples it is more closely related to 

 Protarchus. In many of the characters set forth below it differs 

 from both. 



Head transverse, temples narrowed; eyes divergent below, entire 

 within; clypeus not separated, broad, flat, apex broadly rounded; 

 mandibles large, constricted near base, teeth rounded, lower slightly 

 the longer; maxillary palpi not especially long; malar space short; 

 frons concave, flanked on either side by a strong ridge; ocelli very 

 large, the ocellar area bounded laterally by a deep groove; antennae 

 as long as body, attenuate at apex, scape subcylindrical with apex 

 weakly oblique, ikst flagellar joint not nearly twice as long as second 

 and swollen above near base; epomia absent; notauli deep and meet- 

 ing before the scutellum; prescutum with a median longitudinal 

 ridge; scutellum broad, strongly elevated basally, declivous behind; 

 mesopleurum with a broad longitudinal impression above which it 

 is elevated; prepectal carina reaching top of this impression; pro- 

 podeum short, carinae very strong, basal transverse carina wanting, 

 petiolar area occupying two-thirds of dorsal length, spiracles very 

 large, broadly oval, directed posteriorly; legs slender; hind basitar- 

 sus nearly as long as remaining joints combined; claws simple; inner 

 calcarium about a fourth as long as basitarsus; wings large; stigma 

 very narrow with radius near base; apical abscissa of radius nearly 

 straight; areolet petiolate, quadrangular, second recurrent before 

 middle; recurrent straight with bulla undivided; discocubitus evenly
