PINE BORERS. 685 
16. Drummond's buprestis. 
Melanophila drummondi Kirby. 
This species, with Buprestis rusticorum, and Chrysobothris trinervia. 
we have collected in the pine timber of the mountains of 
Utah in the American Fork Canon, late in July, and it is 
probable that all will be found to inhabit the trunks of 
coniferous trees. It also inhabits Oregon and Washing- 
ton as well as Alaska and New Mexico. (Santa Fe, Snow.) 
Le Conte describes it as being densely punctured, sba- 
greened, with shining, metallic colors, especially on the 
prothorax, with three bright yellow spots on the poste- monk's Me- 
rior two-thirds of each wing-cover, the anterior spot being lanophiia.- 
the larger. Length, 0.40 inch. 
17. The pitted buprestis. 
Dicerca punctulata Schonherr. 
Occurring mostly upon the pitch pine (Pinus rigida), an obscure coppery or black 
beetle, half an inch long, convex above with the tips of its wing-covers tapering, 
and this narrowed portion more lengthened than in any of the foregoing species, their 
surface occupied with close fine punctures and double rows of coarse ones, the nar- 
row spaces between these rows often elevated in places, the elevations forming smooth 
t>blong spots or irregularly interrupted ribs ; the thorax with coarser confluent punct- 
ures and with four elevated smooth stripes, the outer ones narrower and interrupted 
by a slight depression in the surface back of their middle ; and finally, a smooth 
transverse elevation upon its front, extending from one eye to the other, is a mark 
whereby this species may be readily distinguished from most of those related to it. 
(Fitch.) 
I have found a dead beetle under the bark of the pitch pine in the 
same stump with Buprestis lineata in May, 1881, at Providence, R. I. 
18. The tuberculated buprestis. 
Dicerca tubereulata Laporte. 
This is another beetle which is met with upon the pitch pine, and 
resembles an individual of the preceeding species of a more brassy 
tint and having all its marks more coarse, rough, and irregular; but 
the rows of coarse punctures on its wing-covers are at equal distances 
from each other instead of being in pairs, the intervening spaces hav- 
ing many irregular elevated black polished spots,and the elevated trans- 
verse line upon the front is interrupted and less prominent, and its size 
is rather larger, being about 0.60 inch long. (Fitch.) 
19. The pine dicerca. 
Dicerca tenebrosa Kirby. 
Mining under the bark of the white pine, the beetle occurring in October. (G. 
Hunt.) 
Le Conte describes this beetle as follows : 
Ashy bronze or obscurely bronze, the prothorax dilated on the sides, which are 
rounded in front, sinuous behind, coarsely punctured ; behind broadly excavated on 
each side, with apical and basal shining smooth rugosities ; a definite dorsal deep
