PINE BORERS. 



681 



According to Le Conte this beetle inhabits the twigs of the white 

 pine. Mr. George Hunt also informs us that it inhabits the white pine 

 in Ehode Island, where he has collected it late in June and during July.

As this beetle occurs in the pine forests of Colorado, it is most prob- 

 able that it bores in pine trees. It is a rather small, short, broad 

 species, dull blackish, with faint metallic reflections. Surface of the 

 body, especially the wing-covers, with irregular ridges, the inner one 

 parallel to the inner edge of the wing-cover ; wing-covers with smooth, 

 elevated areas, between which the surface is minutely pitted with dense 

 golden punctures. Body clothed beneath with short, coarse hairs. 

 Length, 0.45 inch. (Le Conte.) We collected a specimen on the Divide, 

 Colorado, July 12. Prof. F. H. Snow has taken it at Santa Fe, N. Mex. 



10. The golden buprestis. 



Buprestis striata (Fabr.) 



Order Coleoptera ; family Buprestid^e. 



Appearing upon pine and spruce trees in May and June, a brilliant and sparkling 

 copper-red beetle, 0.55 to 0.70 long, its wing-covers marked with a broad brilliant 

 bluish-green stripe on each and with four elevated smooth lines in which are several 

 deep punctures, the two outer lines nearly or quite united at their hind ends and 

 the exterior middle one a fourth shorter, the depressed spaces between these lines 

 twice as wide as the lines aud rough from coarse confluent punctures; its thorax 

 with a wide shallow groove along the middle, which is sometimes very slight, the 

 surface covered with coarse punctures which become dense aud confluent along the 

 sides, as they are upon the head also, which has a slender elevated line along its 

 middle; the under side brilliant coppery. (Fitch.) 



" Like most of the other insect borers in the pine, it appears to be the 

 dead wood of logs and stumps which this species prefers to living trees.
