Notes on the Coleoptera of Placer County, Calif. 
By JuriaA D. E. WricHT 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 Coccinellide, were found on them. ‘The blossoms of 
of Anstostophylos and Ceanothus were also rich in insect visitors. 
Considerable collecting was done at Lake Alta, a small lake 
below Alta, and around the banks Cicindelide 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 :
