Vol. VIII] VAN DUZEE—NEW SPECIES HEMIPTERA 293 



second segment piceous; third infuscated, paler at base; fourth white, 

 minutely tipped with fuscous. Rostrum pale piceous. Posterior line of 

 silvery hairs on the elytra usually a little sinuated, not at all dislocated at 

 claval suture. Apex of clavus, corium behind the silvery line for its whole 

 width and the cuneus moderately polished and infuscated. Membrane in- 

 fuscated, with a deeper blackish cloud covering the larger areole and ad- 

 joining surface posteriorly. Raised disk of the scutellum bounded by the 

 usual lines of silvery hairs at each side and at the apex. Base of the hind 

 tarsi and often of the tibiae paler brown. 



Described from 32 examples, representing both sexes, taken 

 on coniferous trees at Cayton in eastern Shasta County, Cahf., 

 and at Sisson, CaHf., July 15 to 27, 1918. These were much 

 more abundant on pines but were also taken on firs and cedars. 

 This species may be distinguished by the prominent base of the 

 vertex, the broad, curved hind tibise, and the fuscous third 

 and white fourth antennal segments. I have specimens from 

 Manitou, Colo., that do not differ from this species and Mr. W. 

 M. Giffard has taken it at Donner Lake, Placer County, Calif., 

 at an elevation of 6000 feet. It is probably the common species 

 on pines throughout California. 



Holotype (No. 413), male, and allotype (No. 414), female, 

 from Cayton, and paratypes in collection of the California 

 Academy of Sciences. 



23. Pilophorus crassipes, new species 



Allied to tibialis but with narrower hind tibiae ; vertex with 

 a median sulcus; membrane with a blackish lunule behind the 

 areoles ; length 6 mm. 



Head broad triangular and flattened much as in tibialis. Base of the 

 vertex much depressed ; hind margin strongly elevated ; median line sul- 

 cate ; front of vertex with evident striae ; apex of the cheeks narrowly 

 truncate, considerably exceeded by the clypeus ; sides of the head bluntly 

 carinate before the eye as in the allied species. Second antennal segment 

 rather thicker than in either amocnus or tibialis, becoming less abruptly 

 narrowed toward the base, thus giving the antennae a heavier look; third 

 segment nearly twice the length of first and almost as thick; fourth three 

 fourths the length of third and more slender. Rostrum attaining the hind 

 coxae ; the basal segment much surpassing the bucculae but not reaching 

 the base of the head. Pronotum broader than in tibialis and amccnus; as 

 wide as the head across the eyes ; disk posteriorly strongly rugose-shag- 

 reened. Posterior line of silvery hairs on elytra entire, not dislocated at 

 claval suture; the surface of the clavus and corium behind this line and the 

 cuneus polished. Hind tibiae long, flattened and curved but not so strongly 

 as in tibialis, its greatest width about half that of the femora. Upper sur- 

 face, of the elytra at least, clothed with scattering short erect stiff fuscous 

 hairs.
