301. Empoasca onreovindis (Uhl.) Fallen Leaf Lake, 

 August 21, 1916. 



302. Empoasca sublactea, new species 



Allied to aureoviridis and smaragdula ; smoky greenish; pronotum 

 and usually the vertex with three whitish marks ; elytra milky-hyaline, with 

 the sutural and commissural nervures slenderly fuscous. Length 5 mm. 



Vertex short, regularly rounded, of equal length across its whole width. 

 Face as in smaradula; sides of the front nearly rectilinear; clypeus regu- 

 larly narrowed to an elliptical apex. Pronotum as in the aUied species, 

 the humeral angles broadly lobate as in smaragdula, the arcuation across 

 the base of the scutellum being nearly rectilinear. 



Last ventral segment of the female longer than in aureoviridis, when 

 viewed from the side abruptly notched for about half its width. Last ven- 

 tral segment of the male shorter than in the female, but little produced, 

 the sides very feebly notched ; plates when viewed from below obtusely 

 triangular ; their long, twisted, upturned apices, when viewed from the 

 side, much broader and more truncate at apex and clothed with longer 

 bristles than in smaragdula ; hind margin of the pygofer viewed from the 

 side, vertical, very slightly arcuated, the dorsal angle forming a distinct 

 blunt tooth. In smaragdula this twisted apex of the plates is narrower and 

 eUiptical at apex, and the hind margins of the pygofer is strongly arcu- 

 ated, with the dorsal angle scarcely produced.
