sides strongly incurved and suddenly and strongly broadened 



apically Idiocerus Lewis. 



c^ Outer apical cell in tegmina continuous with the outer subapical, 



the cross vein lacking (always to be examined by transmitted 



light), thus never more than two closed subapical cells; vertex 



usually longer at middle than next eyes, and very long for this 



group, in proportion to width between eyes. 



d\ Upper lateral sutures of front obsolete, the lower lateral sutures 



continuous with the supra-antennal ridges, the front thus very 



broadly open above; ocelli nearer to eyes than to median line, 



or as near Busonia Dist. 



<P. Upper lateral sutures of front distinct, always distant more than 

 half the distance from supra-antennal ridges to ocelli; ocelli 

 rarely much nearer to eyes than to median line of face. 

 e^. Upper lateral sutures of front each directed toward the inner 

 margin of the ocellus of the same side or nearly so; head 

 distinctly vidder than pronotum. 

 f. Tegmina with three apical cells and without subapicals. 



Balocha Dist. 

 f. Tegmina with four apical cells. 



gr\ Subapical cells absent Pedioscopus Kirk. 



g'. Subapical cells (one or two) present... Idioscopus gen. nov. 

 e^ Upper lateral sutures of front strongly incurved, and from 

 near scrobes each directed toward the ocellus of the opposite 

 side, the front thus appearing far broader than long, and 

 with very strong lateral angles; head about as wide as 

 pronotum; second apical cell pedunculate in present species; 

 first apical cell much broader and shorter than fourth; 

 ocelli nearer to median line than to eyes.. Idiocerinus gen. nov.

Iposcopus distanti sp. nov. 



Length, 4.5 mm. ; width of head, 1.8 mm. Head straw-colored 

 with dark mottlings on upper part of face, including two irreg- 

 ular dark spots between ocelli and upper margin ; clypeus, lorae, 

 and lower part of cheeks blackish. Pronotum brownish, two 

 small transverse dashes back of eyes blackish, and hind margin 

 yellowish. Scutellum brown, with two black basal lunulas and 

 a broad, bright yellow transverse band back of middle ; the apex 

 brown. Mesopleurse blackish. Tegmina brown, with a narrow 

 transverse band near base, nearly continuous with that on scu-
