122 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 



Described from two female specimens taken by me from 

 mistletoe, Phoradendron villosum, growing on oaks at Sisson, 

 California, July 24 and 26, 1918. The more convex form 

 and different puncturation of head will distinguish this 

 species from both canadensis and pacificus. 



The paratype is larger and tinged with green on the ab- 

 domen and may be somewhat immature. 



Holotype, female, No. 769, Mus. Calif. Acad. Sci.; the 

 paratype also in Academy's collection. 



Type locality, Sisson, Siskiyou County, Calif. 



14. Dichrooscytus vittatus, new species 



Allied to irroratus, but with a fuscous vitta across apex of 

 corium, an oblique mark on inner angle of clavus, longer 

 elytra and different male genitalia. Length 5 mm. 



Head nearly vertical, more convex than in suspectus, about as in irroratus 

 but with the vertex much broader ; basal width of vertex subequal to length 

 of pronotum in female, a little less in male, basal carina very feeble, the 

 surface before it scarcely depressed ; eyes much smaller than in irroratus; 

 antennae long, reaching to apex of cuneus; segment II four times length of I, 

 subequal to the corium ; III twice as long as IV, these together three-fourths 

 of II; rostrum attaining apex of hind coxae. Pronotum twice wider than 

 long, nearly smooth, callosities small, distant; costal margin of elytra a little 

 arcuate posteriorly, clothed with rather long prostrate pubescence; cuneus a 

 little longer than its basal width. Sinistral male clasper broad for this genus, 

 the two branches of nearly equal width, the ventral attaining apex of genital 

 segment, broad and rounded at apex; dextral clasper short, rounded, with a 

 minute hook at its dorsal angle. 



Color, yellowish or greenish, more or less marked with sanguineous on the 

 vertex, anterior lobe of pronotum, middle of scutellum and disk of corium; 

 apex of corium with a rather broad transverse fuscous vitta, becoming san- 

 guineous toward the costa ; at inner angle of clavus a fuscous cloud which 

 may be extended basally or even wanting; cuneus conspicuously pale, sulphur- 

 yellow, sanguineous at tip; membrane hyaline, slightly infuscated at apex with 

 a darker spot at tip of cuneus and in apex of each areole. Beneath, with the 

 antennas, rostrum and legs including coxas, paler or whitish; pleurae and sides 

 of venter washed with sanguineous; tip of rostrum and of tarsi black; tergum 

 sanguineous or blackish; tibial spines short, brown. 



Described from two male and seven female examples 

 taken by me at Huntington Lake, Fresno Co., Calif., July 

 27, 1919, at an elevation of 8,000 feet, one female from 

 Colestin, Oregon, July 31, 1918, four females from Cayton, 

 Shasta Co., Calif., July 14, 1918, and one pair taken at 

 Fallen Leaf Lake, Eldorado Co., Calif., July 30, 1915. 

 This is the species listed by me as irroratus in my report on
