brown ; elytra subhyaline, the nervures alternately black and white, 

 white at base, an oblique black band across the center of the claval 

 nervures and extending to the center of the costa, another from the 

 apex of the clavus behind the nervures transversely to the center of the 

 costa, apical nervures reddish-brown, the cross nervures between the 

 first and second nervures broadly white. 



Genitalia : 9 ultimate ventral segment very short on lateral mar- 

 gins, roundingly produced and shallowly notched, pygofers short and 

 inflated: cJ* valve broad, with a median acute tooth and sharp lateral 

 angles. 



Described from four females and one male. Larvae and adults 

 taken from cotton wood in July. 



This species is very distinct and at once readily separated from 

 other described species by the position of the white markings on the 

 elytral nerves. 



Idiocerus brunneus n. sp. (Plate III., Fig. 3.) 



Form of lachrymalis nearly, but smaller, resembling the Europ-jan 

 1. scurra in form and color, but smaller and wanting the outer ante- 

 apical cell to the elytra. Cinnamon-brown with two black spots on 

 the vertex. Length, 5.5 mm.; width across the eyes, 2 mm. 



Vertex very broad and stout, eyes much more prominent than in 

 alternatus, nearly half their width beyond the margin of the pronotum. 

 Face very broad and short, front broad and very convex in both 

 diameters, the outer margin of the genae concave, clypeus one-third 

 longer than broad. Pronotum rather short, elytra broad, the appen- 

 dix narrow, only slightly overlapping behind. Venation distinct, the 

 nerves strong, thickly set with minute tubercles, outer anteapical cell 

 wanting, the outer branch of the outer fork of the first sector curving 

 away to the costa immediately, or at most forming a small triangular 

 cell in the fork. 



Color : Dull cinnamon-brown. Vertex and face tawny-yellow, a 

 pair of black spots on the vertex and an olive brown area between 

 them and extending nearly down to the dark ocelli, pronotum olive- 

 brown, testaceous on the depressed spots behind the eyes, scutellum 

 cinnamon-brown in the female, yellowish with three triangles on the 

 base and two spots on the disc black in the male. Elytra brownish 

 sub-hyaline, nervures brown, dark at apex. 



Described from numerous examples.
