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 Rhode 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 BuPRESTiDiE. 
Appearing upon pine and spruce trees in May and June, a brilliaut aud sparkling 
copper- red beetle, 0.55 to 0.70 long, its wing-covers marked with a broad brilliant 
bluish-green stripe on each aud 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 and 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 and 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,
