Notes on some Buprestidae of Northern Califor- 

 nia (Col.). 



By W. J. CHAMBERLIN, Forest Entomologist, Oregon State Col- 

 lege, Corvallis, Oregon. 



This paper is the result of observations and collections made 

 during two summers spent in northern California. The sum- 

 mer of 1915 was spent at Weed, a small lumbering town in 

 Siskiyou County, at the base of Mt. Shasta. The general ele- 

 vation surrounding Weed is 4500 feet. The summer of 1916 

 was spent in Siskiyou, Del Norte, Humboldt and Mendocino 

 Counties of California. 



Regarding the species taken at Weed it might be well to men- 

 tion that there are from 50 to 60 cars of logs brought in daily 

 from the Trinity Mountains, some thirty miles distant. It is 

 probable that the majority of the forest insects are brought in 

 with this timber, though undoubtedly some are attracted from 

 the surrounding territory by the odor of fresh pine. 



Buprestids were by far the most numerous beetles occur- 

 ring in the vicinity of Weed and over 450 specimens were taken 

 at odd times during a six weeks' stay. 



1. Chalcophora angulicollis Lee. 



Twenty-six specimens of this species were taken at Weed 

 in 1915. The majority were captured resting in the bright 

 sunshine, on buildings, telephone poles, on the wooden side- 

 walks and a few were taken while in flight. No less than ten 

 specimens were taken on piled lumber. They attract attention 

 by the rasping sound made in flight and are easily captured in 

 the hand. They seem to be attracted by moving objects and 

 will often alight on horses, moving wagons, or on man. 



This species is common all over the northern half of the 

 State, breeding in yellow pine, Douglas fir, white and grand 

 fir. 



2. Dicerca prolongata Lee. 



This species has been taken by Dr. Van Dyke on Populns 

 trichocarpa in Trinity County, California, and on Populus 

 trenndoidcs at Lake Tahoe. It breeds in P. trichocarpa and 

 doubtless in P. tremuloides also.
