14 PEOCEEDINGS OF THE NATIONAL MUSEUM vol.80 



Yi may be fused with spot 1 to form a transverse black fascia. Length 

 of the body, 5.8-6.8 mm. 



Male genitalia (fig. 5). — Resembling those of C. calif ornica; but the 

 process on the distal end of the penis shorter, broader, and less acu- 

 minate at the end. 



Female genitalia (fig. 23). — Not distinguishable from C. calif ornica. 



This species is very close to C. calif ornica but not to C. novemno- 

 tata, as suggested by Johnson and Leng. Its specific rank may be, 

 however, a subject of dispute. Indeed, the very small differences in 

 the structure of the genitalia and in the form of the body might make 

 it questionable. No intermediates between the two species occur, 

 however, in spite of the fact that the whole known distribution of 

 C. johnsoni is included in that of C. calif ornica. Notwithstanding the 

 smallness of the differences between the two species, and the varia- 

 bility of the elytral pattern of C. johnsoni, they may be distinguished 

 without difficulty. The species described by Casey (1908, p. 402) 

 from northern Mexico, namely, Coccinella sonorica, is almost certainly 

 a color variation of C. johnsoni. 



Geographic distribution. — Localities as follows: 



British Columbia: Victoria (California Academy of Sciences collection). 

 Washington: Orcas Island (W. M. Mann collector), King County (F. W. 



Nunenmacher collection). 

 California: Shively (E. O. Essig collector), San Francisco (F. T. Scott collector), 



Santa Paula, Pasadena, Fish Canyon, Santa Ana, Santa Monica, Costa Mesa, 



San Diego, Coronado, San Nicolas Island (S. Emerson collector), San 



Clemente Island (F. Blaisdell collector). 



Remarks. — The individuals from British Columbia and Washington 

 are rather considerably different from those from California in being 

 less convex, in having the apex of the elytra acuminate, and in having 

 very small elytral spots. This fact suggests that the species C. johnsoni 

 is differentiated into two subspecies, one of which is living in British 

 Columbia and Washington and the other living in California. It 

 seems to be wise, however, not to propose Latin names to these sub- 

 species until more material is available,
