specimens have been found with the typical green ones. Most 

 of these have been taken from the wood scars on the trunks of 

 living trees. 



In western Oregon and western Washington, especially the 

 lower Columbia River Basin, blondeli is found in the western red 

 cedar or giant arbor vitae (Thuja plicatd) where it causes a good 

 deal of damage to the timber. Scars on the trunks and tops of 

 the standing trees are the best places to look for it. 



T. opulenta Fall. This close relative of blondeli appears to 

 be confined to the Sierras at elevations of from 2000 to 6000 ft. 

 It lives in the wood of the incense cedar (Libocedrus decurrens) 

 and of the big tree (Sequoia washingtoniana] and sometimes in 

 the thick bark of the latter. Stumps and scars on the trunks of 

 standing trees produce the best results. As many as a dozen 

 live beetles and many dead ones have been taken from a single 

 scar. Good collecting grounds are found along the Lincoln High- 

 way near Strawberry, El Dorado County, and in the Giant 

 Forest of the Sequoia National Park. 



T. nimbosa Fall. Scars on the trunks and in the tops of the 

 red fir (Abies magnified), the white fir (A. concolor) and the moun- 

 tain hemlock (Tsuga mertensiana) are the best places to look for 

 nimbosa. It is fairly common in the higher forests of El Dorado 

 County and in the Sequoia National Park at elevations of from 

 5000 to 10000 ft. 



T. sp. Within the past year Mr. R. D. Hartman of the Forest 

 Insect Laboratory, collected some large dark ashy-gray bronze 

 beetles which appear to form a distinct new species of Trachykele. 

 These were taken from the wood of the scarred trunks of the 

 Sargent cypress near the Toll House, Mt. St. Helena Creek, Lake 

 County, Calif. 



Buprestis Linn. 



B. gibbsii Lee. This is one of the rarest of the Buprestidae in 

 collections. The specimens obtained by the writer were taken 

 in Tuolumne County, Calif., along the old Sonora-Mono road 

 near Confidence at elevations of from 4000 to 6000 ft., and at 

 Onion Valley, El Dorado County at an elevation of 4500 ft. Mr. 

 Albert Wagner, of the Pacific Forest Insect Station, took one 

 specimen in southern Oregon at 2000 ft. This was depositing 

 eggs in a crevice in the wood of a scar on the trunk of a living 

 tree. All of the specimens cut from the wood were taken from 

 the solid heartwood of old fire scars on the trunks of the black 

 oak (Quercus calif ornica}. Many of the fire scarred trees have 

 the heart eaten out by Termites. Usually the sap wood of the 

 scars still remains and is heavily infested with Polycesta califor-
