1918] Buprestis Linne in California 91 



Buprestis maculiventris var. riisticorum Kirby, 16-23 mm. 

 in length, is found commonly in Northern California and breeds 

 in yellow pine, Douglas, alpine, and white fir. Specimens in 

 my collection were taken at Weed, St. Helena, Tahoe Tavern 

 and Donner Lake, between May 25 and July 21. 



Buprestis adjecta LeConte, 12-19 mm. in length, is scarce 

 as a rule, and is found in the higher Sierras breeding in yellow 

 and other alpine pines, probably also Jeffrey. Specimens in 

 my collection were taken at Donner and Independence Lakes, 

 July 3-15. 



Buprestis fasciata Dejean, 10-19 mm. in length, is taken in 

 the Sierras of northern California and is known to bore in 

 Douglas fir, while the female, usually known as var. langii 

 LeConte, has been taken by myself. Dr. E. C. Van Dyke and 

 others resting on the foliage of alder and willow. Specimens 

 in my collection were taken at Donner Lake, Tahoe Tavern, 

 Muir Woods and Willits, between June 10 and July 21. 



Buprestis gibbsii LeConte, 12-21 mm. in length, is taken 

 very rarely in California. It has been taken from oak by Mr. 

 E. Leach of Oakland and by Dr. E. C. Van Dyke. This past 

 summer I removed adults from their pupal chambers in cotton- 

 wood at Oro Grande, San Bernardino County. Specimens in 

 my collection were taken at Oro Grande and in Trinity County, 

 between May 18 and July 29. 



Buprestis confluens Say, 15-16 mm. in length, is taken 

 exceedingly rarely in California, in the Great Basin and Tahoe 

 regions. It works on poplars. Specimens in my collection 

 were taken at Tahoe Tavern and in Colorado, July 1-22. 



Buprestis connexa Horn, 14-15 mm. in length, is taken 

 extremely rarely in Washington, Oregon and the eastern base 

 of the Sierras in California. It works on alpine trees, having 

 been taken from western yellow pine. One specimen in my 

 collection taken at Donner Lake, July 7. 



I have tried trapping by sawing up fresh pine wood at several 

 localities, but without success, except at Donner Lake in 1915, 

 between July 1 and 15. In three days I collected from a pile 

 of yellow pine chunks 64 specimens of Buprestis, as follows: 

 41 aurulenta, var. riisticorum 20, adjecta 2, connexa 1. These 

 three days were separated over several weeks, as I returned to
