One specimen was reared from buprestid borings at Wellington, 

 B. C, Apr. 17, 1945, by R. Guppy. A female from Monterey Co., 

 Calif., is labeled "Pinus radiata." In our own collecting we have 

 found the species in Pseudotsuga forests. At Mount Rainier, Wash., 

 we collected a series of both sexes around a pile of coniferous firewood. 



This species is in coniferous forests, from British Columbia to a 

 little south of San Francisco, in the Transition zone. It has been 

 reared from a buprestid.
