Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 287 



193. Stictocephala wickhami Van D. Fallen Leaf Lake, 

 August 21, 1916; Tallac, August 22, 1916; Tahoe City, Au- 

 gust 23, 1916; Summit, Placer Co., August 24, 1916. In 

 California this species seems to be confined to the higher 

 altitudes, while pacifica is found mostly along the coast belt. 



194. Stictocephala franciscana Stal. Portola Valley, San 

 Mateo Co., May 4, 1917; Santa Cruz Co., 1500 feet, June 8, 

 1917; Niles Canyon, July 24, 1916; near Stockton, May 25, 

 1917; Laurel Dell, Lake Co., August 2, 1916. This species 

 seems to take the place of festina on the alfalfa fields in cen- 

 tral and northern California. 



195. Telamonanthe rileyi (Godg.) San Francisco, June 25, 

 1916; Los Altos, July 26, 1916; Mt. Tamalpais, August 16, 

 1916; Walnut Creek, August 10, 1916; Mt. Diablo, 1400 feet, 

 July 23, 1916. 



196. Cyrtolobiis vaiidusei (Godg.) Niles Canyon, May, 

 1916; Mt. Diablo, July 23, 1916. 



197. Platycotis vittata (Fabr.) Wawona, June 17, 1916; 

 Placer Co., August 20, 1916. The latter specimens pertain 

 to the unmarked form described as sagittata Germ, which, 

 possibly should be regarded as a color variety; both these 

 have the porrect horn. An immature unarmed specimen of 

 var. quadrivittata Say was taken at Wawona wMth the typical 

 form. 



198. Platycotis maritimus, new species 



Intermediate between vittata and minax, but more closely related to 

 the former ; pronotum unarmed in all individuals seen by me ; greenish or 

 brownish, more or less varied with darker, median carina black in part. 

 Length to tip of elytra 8 mm. 



Head nearly as in vittata, the anterior margin more evenly arcuated 

 and distinctly reflexed than in the allied form; surface distinctly wrinkled 

 vertically with prominent percurrent median carina. Pronotum similar 

 to that of vittata, with finer, distinct punctures ; median carina attaining 

 the anterior margin ; cicatrices distinctly smaller and shorter than in 

 vittata, beginning abruptly about two-thirds their own length from the 

 median carina and terminating just beyond the inner line of the eyes. In 

 vittata they end indefinitely very near the median carina and extend lat- 

 erally fully to the middle of the eyes ; humeri prominent and obtuse ; apex 

 usually acute, attaining the middle of the inner apical areole. Elytra hya- 

 line, with strong brown nervures, barely touched with smoky at apex 

 beyond the apical nervure. Last ventral segment of the female deeply 

 roundedly excavated almost to its base ; plates of the male subterete, par- 

 allel and approximate, reaching distinctly beyond the tumid sides of the 

 pygofers, which in this species are much expanded. 



Color about as in vittata and exhibiting similar variations; testaceous 

 or yellowish brown, sometimes more or less tinged with greenish ; me-
