long as the two terminal ones united, which are slender and subequal 

 in length; rostrum reaching the middle coxae, black, sometimes more 

 or less brownish; basal joint very broad compared with the other joints. 

 Pronotum broader than long; anterior margin about half as wide as 

 the posterior margin; the lateral margins almost straight, not sharply 

 carinated, anteriorly gently rounding beneath the eyes 

 and more abruptly at the humeri; the callosities not 

 very prominent, transverse, reaching the sides, a little 

 depressed behind and with two linear impressions an- 

 teriorly; the collum well defined; disk of pronotum 

 somewhat convex, feebly sloping anteriorly; surface 

 irregularly, quite strongly wrinkled and confluently 

 punctured, the punctures becoming more shallow near the posterior 

 margin of pronotum. Scutellum transversely fine rugose, depressed 

 at base and with a smooth little tubercle at tip. Hemilytra much 

 finer wrinkled and punctured than the pronotum; cuneus slightly in- 

 cised at base exteriorly, blunt at tip, and somewhat impressed at inner 

 side basally; membrane smoky, longitudinally rugose, the two cells 

 smooth; a narrow whitish streak at the side of cuneus apically and 

 which runs diagonally along the apex of the cells. Abdomen, breast, 

 and the pleural pieces black, highly polished; acetabular caps and 

 ostiolar canal yellowish-white. 



Feet black, except apical part of coxae, the trochanters and the 

 greater part of the tibias yellowish, the latter remotely beset with 

 black bristles; tarsal joints and claws black. A few specimens have 

 the femora also yellowish, which indicates only a color variety. The 

 arolia at base of claws are free and divergent. 



Length to the tip of membrane o mm. ; width across hemilytra 2 

 mm. 



Described from two examples, male and female; besides, 

 many more specimens have been examined. 



Type: No 13227, U. S. National Museum.

This new species comes nearest to Caps/is atcr Fabr., with 

 which it has in common the peculiarly sculptured pronotum, 

 but differs in not being quite so robust and having the second 

 antennal joint not clavate. Regarding geographical distribu- 

 tion it seems to be a Western species. It extends on the Pacific 

 Slope as far north as Olympia, State of Washington. Speci- 

 mens have also been collected in the Wasatch Mountains, Utah, 

 In California it occurs abundantly on Lnpiuus and is lately 

 recorded from that region as injuring potato plants.
