Notes on the Coleoptera of Placer County, Calif. 

 BY JULIA D. E. WRIGHT AND KARL R. COOLIDGE. 



The following species of Coleoptera were taken in the vicin- 

 ity of Towle, Dutch Flat, and Alta, small mining towns of 

 Bret Harte fame. In 1903 the former writer spent June, July, 

 August, and a part of September at Towle, and April and May 

 of 1907 were spent by the latter at Alta. Placer County is in 

 the foothills of the Sierra Nevadas, the elevation at Alta being 

 about 4000 feet. Pinus ponderosa and P. lambertiana are char- 

 acteristic trees of that region, and many species, particularly 

 in the Coccinellidce, were found on them. The blossoms of 

 of Anstostophylos and CeanotAuswere also rich in insect visitors. 

 Considerable collecting was done at Lake Alta, a small lake 

 below Alta, and around the banks Cicindelidae' were found 

 abundantly. There is a good hotel at Lake Alta, and we 

 would recommend this locality as an excellent entomological 

 one. The following list is far from complete, but, from time 

 to time, we hope to be able to add to it. We are much 

 indebted to Drs. Blaisdel and Van Dyke for many identifi- 

 cations :
