Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 253 



20. Tollius curtulus Stal. Siskiyou, southern Oregon, 

 July 10, 1917; Tallac, August 22, 1916. The latter, a fe- 

 male, differs from the more typical form of the species in 

 having the elytra pale, regularly and conspicuously maculated 

 with fuscus. 



21. Tollius setosus (Van D.) Santa Cruz Co., May 8, 

 1917. The most abundant form in the coast counties. 



22. Coriomeris humilis (Uhl). Santa Clara Co., June 11, 

 1917; Portola Valley, May 14, 1917; Muir Woods, July 



15, 1917. 



23. Aiifiiis imprcssicollis Stal. Near Stockton, May 30, 

 1917. 



24. Harmostes reflexiilus (Say). Crystal Springs, June 

 25, 1916; Los Altos, July 26, 1916; Blue Lakes, August 3, 

 1916; Tallac, August 22, 1916; Portland, Oreg., July 5, 

 1917; Seattle, Wash., July 7, 1917. The pink form de- 

 scribed by Dr. Bergroth as hruesi seems to me to be identical 

 with the typical form of this species. It is the most abundant 

 phase of this species as found in California. 



25. Corkus hyalinus (Fabr.) Crystal Springs, June 25, 

 1916. 



26. Corimis validus Uhl. Yosemite, June 16, 1916; Fallen 

 Leaf Lake, August 21, 1916. 



27. Corkus lateralis (Say). Los Altos, July 26, 1916; 

 Clear Lake, August 2, 1916, on shore weeds; Soda Springs, 

 August 24, 1916. 



28. Corimis scutatus (Stal). Walnut Creek, August 10, 

 1916, one deeply colored example. 



29. Corizus indcntatus Hambl. Muir Woods, August 



16, 1916; Mt. Diablo Park, July 23, 1916; Wawona, June 



17, 1916; Portland, Ore., July 3, 1917. 



30. Leptocoris trivittatns (Say). Tunnel Road, Alameda 

 Co., May 3, 1917; nymphs taken July 17, 1917.
