specimen, and the description of it is unsatisfactory. C. nevadica 

 may also be a spotless variety of C. nivicola Menetries, or even may 

 be synonymous with C. novemnotata Herbst veLT.Jranciscana Mulsant.

Remarks. — One may conclude from the data presented above that 

 C. californica is very common between the Coast Range and the 

 Pacific Ocean, but occurs only very seldom between the Coast Range 

 and the Sierra Nevada. It is the commonest species of Coccinella 

 in the Los Angeles region, but seems to be entirely absent in the 

 Mohave Desert. F. T. Scott informs me that C, californica is not 

 found in the central part of the San Joaquin Valley, being replaced 

 there by C. novemnotata Herbst var. franciscana Mulsant, which is 

 not very common in the Los Angeles region. The finding of 

 C. californica in Arizona and at Lindsay, Calif, (see above) seems to 

 be very doubtful. It is probable that this species will be found also 

 along the western coast of the northern part of Mexico.

Body more elongate and less convex than in C. californica Man- 

 nerheim. Punctulation of the pronotum and the elytra somewhat 

 stronger than in the latter species. Elytra red with the 11 spots con- 

 stituting the typical pattern of the genus Coccinella (fig. 30), and with 

 a narrow black stripe along the suture. Spots 4 and 5 lie close to 

 each other, and are frequently confluent. The black sutural margin 

 maybe absent; likewise spot 2, or spot 4, or both, may be absent. Spot
