Vol. VI] VAN DUZEE— SPECIES OF ORTHOTYLUS 99 



Color a uniform clear green, becoming yellowish on the 

 callosities, head and beneath. Antennae and legs dull testa- 

 ceous, the apex of the antennae somewhat infuscated. Mem- 

 brane moderately infuscated, iridescent, the nervures green, 

 vestiture of the upper surface minute and sparse, fuscous. 



Say's material was from Indiana. I possess examples from 

 Quebec, District of Columbia and California. This pale green 

 little species may be distinguished from flavosparsus by the 

 concolorous areoles and the want of intermixed pale hairs; 

 from fraterniis and uniformis, by the shorter elytra, and from 

 translucens, by the dark vestiture and the genital characters of 

 the male. 



8. Orthotylus fraternus, new species. 



Very close to translucens, but with longer elytra clothed 

 with fuscous instead of pale hairs. Length 4mm, to tip of 

 the elytra. 



Head substantially as in translucens, but with a transverse 

 linear impression before the basal carina. Antennae obviously 

 more slender, Pronotum shorter than in the allied species, the 

 sides feebly concavely arcuated with the angles more rounded. 

 Elytra longer, the apex of the abdomen not surpassing the tip 

 of the corium, the cuneus noticeably longer. The male genital 

 characters are very close to those of translucens, but there are 

 some differences. The dextral hook is more clavate at apex, 

 the sinistral more curved and less inflated and the ventral as- 

 pect of the genital segment is shorter and less acutely pro- 

 duced. 



The color of the present species is distinctly darker and 

 more olive green, becoming yellowish toward the costa ; the an- 

 tennae are darker throughout, the hairs on the upper surface are 

 distinctly fuscous instead of pale, and the longer bristles of 

 the tibiae are blackish. 



Described from five male examples taken at La Jolla, Calif., 

 April 29, 1914; Alpine, San Diego County, Calif., June 5, 

 1913, and Pasadena, Calif., in May. This species I place next 

 to chlorionis on account of its fuscous vestiture, but it is very 

 close to translucens, although I believe it quite distinct. The 

 genital characters are of little value here, but the darker color, 

 longer elytra, fuscous vestiture, slender cuneus, more slender
