26. Orthotylus pullatus, new species. 



Closely allied to hrunnens; blackish, the costal margin 

 narrowly pale ; male genital segment long and unusually slen- 

 der. Length 4^ mm. to tip of membrane. 



Basal impression of the vertex large, including two con- 

 spicuous pits, the basal carina prominent ; front but moderately 

 convex. Eyes, viewed from the side, ovate, reaching nearly to 

 the gula. Pronotum proportionately shorter than in hrunneus, 

 the sides distinctly arcuated with the humeral angles subacute 

 and upturned; callosities large and prominent. Elytra a little 

 more widened toward the apex of the corium than in the allied 

 species. Antennas a little thinner than in hrunneus, the third 

 and fourth joints together scarcely as long as the second. 



Genital segment of the male in hrunneus triangular, hardly 

 longer than broad at base ; in pullatus nearly cylindrical, about 

 twice as long as wide at base, the apex elliptically rounded. 

 Genital hooks small and black ; the dextral elongate ovate, 

 curved inward and backward at apex; the sinistral elongated, 

 lying along the sinistral notch, its apex rounded. 



Color blackish-fuscous. Head black, apex of the clypeus 

 sometimes touched with castaneous. Antennae black. Pro- 

 notum at times showing a mere tinge of castaneous behind the 

 callosities. Coxae at base and the middle of the sternum and 

 venter pale. Elytra a shade paler than the body, the costal 

 margin narrowly pale and extended nearly to the apex of the 

 cuneus. Membrane nearly black, the nervures concolorous or 

 barely touched with pale at apex. Legs dark castaneous. Up- 

 per surface clothed with pale pubescence. 



Described from one male and eight female examples taken 

 by me May 13, 1915, on willows growing among the sand 

 dunes at San Francisco, Calif. This species is best distin- 

 guished from the closely allied hrunneus by the darker color, 

 the prominent, subacute, humeral angles, and the long, nar- 

 row male genital segment.
