Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 267 



and rather distant punctures ; hind edge subangularly sinuated. Elytra 

 strongly convex, coarsely, deeply punctate ; embolium broad at base but 

 soon becoming confused with the swollen posterior disk. Scutellum 

 strongly convex, polished. Sinistral genital hook of the male with a 

 long distal horn. 



Color yellowish testaceous, sometimes tinged with carneous, clouded 

 with piceous brown and strongly punctured with brown. Face fulvous 

 brown, normally with the base of the vertex, a median line and the cly- 

 peus pale, the latter with a geminate brown line on its basal one-half, the 

 sutures of the cheeks slenderly piceous. Pronotum with the collum broad 

 and strongly arcuate, polished ; a large spot on the callosites and some- 

 times the disk posteriorly black; hind edge slenderly pale, the median 

 line more or less distinctly pale. Scutellum polished black, the basal 

 angles, apex and median line usually pale. Elytra with a spot at base, a 

 large one on the middle and the apex broadly piceous. These marks or 

 at least the basal may become obsolete or almost confluent. Cuneus pale 

 or carneous, the immediate base and broad apex black. Membrane fulig- 

 inous, darker at base, with a faintly paler spot at tip of the cuneus, which 

 may become a transverse band. Beneath more or less sanguineous, paler 

 on the coxae and often becoming piceous on the abdomen, the sides of the 

 venter in pale examples being marked with a row of piceous spots. An- 

 tennas pale, the thickened apex of the second segment black and there may 

 be a dusky annulus near the base of this segment. Legs pale, the hind 

 femora with a broad sanguineous or piceous annulus before its apex ; 

 tibiae triannulate with brown, the basal band often obsolete. 



Described from a good series of both sexes taken by Mr. 

 Giffard at Fallen Leaf Lake, August 21, 1916, and Donner 

 Lake, August 24, 1916. Three individuals taken near Clear 

 Lake, Lake Co., August 2. 1916, are a little larger, paler and 

 more sanguineous with the membrane paler, leaving the 

 nervures brown, becoming black at apex. These individuals 

 may be slightly immature. The pale fenestrate base of the 

 cuneus will distinguish this form.

 Soda Springs, Placer Co., August 24, 1916; Summit, Placer 

 Co., August 24, 1916; Donner Lake, August 24, 1916. This 

 has a closer and finer puncturation than our allied western 

 forms. It may be distinguished from the eastern nitens by 

 the dark, annulated antennae and legs and the fuscous apex 

 of the membrane. Our specimens differ from the eastern ex-
