Body broadly oval, strongly convex. Head with a white spot on 

 each side near the eyes, pronotum with a quadrangular mark in the 

 anterior angles, pronotal epipleura with a narrow white margin. The 

 variety melanocollis Casey has the whole pronotum black. Mesepi- 

 mera wliite, metepimera black. Pronotum and elytra slightly 

 alutaceous, densely but finely punctulate, the punctures becoming 

 stronger toward the external margin of the elytra. Elytra bright 

 red or orange with a black scutellar spot (]£) and with a narrow black 

 stripe along the suture. In some specimens the elytra are entirely 

 red (var. nevadica Casey ?). Very seldom individuals occur having 

 rudiments of the elytral spot 1, or the spot 3, or both. Length of 

 the body, 5.4-6.5 mm.

Male genitalia (figs. 4, 15) .—Penis sUghtly longer than the paramera, 

 broadening distally, deeply emarginated in the distal half of its 

 length, and extended into a very broad triangular process. Basal 

 plates broader than long. Sipho shorter than in C. transversoguttata 

 Falderman and in G. novemnotata Herbst. 



Female genitalia (fig. 22). — Receptaculum seminis similar to that 

 of C. novemnotata and C, transversoguttata. The infundibulum longer 

 and more slender than in the species just mentioned. 



This species is rather closely related to C. transversoguttata. This 

 relationship is correctly recognized by Leng, but these species must 

 be undoubtedly considered separate because of the difference in the 

 structure of the genitaUa, as well as in the external characters. I 

 place Coccinella nevadica Casey as a synonym of californica Man- 

 nerlieim with much hesitancy. I have not examined the Casey type
