of the thorax hasiu its middle a well marked, elevated, Hmooth spot, which is oblong 
and pieced obliquely, witli an oblique groove on its outer side separating it from a 
smooth and somewhat triangular spot on the outer margin, which is more distinct in 
this than in either of the preceding species, and produces a slight undulation of the 
outer edge, this edge being almost rectilinear with the opposite sides, parallel with 
each other two-thirds of their length, and then abruptly or angularly inclining 
inwards to the anterior angles. The wing-covers have the elevated lines much 
broken and irregular, resembliug those of the precediug species, though on a partic- 
ular examination several differences will be noticed. (Fitch.) 
Tbis insect has also been found by Dr. LeConte, at Sacramento, Cal. 
6. Chalcophora foriis Le Coute. 
This beetle has been observed by Mr. W. Hague Harrington on the 
pine I extract his account of it from the transactions of the Ottawa 
Field Naturalist's Club, No. 2, p. 28. 
The largest species is Chalcophora for tis, a remarkable fine beetle, varying from one 
to one and two-tenths inches in length, and being about three-tenths of an inch wide. 
Their color is a coppery brown, but newly emerged specimens have often a golden- 
greenish burnish, or a powdery appearance caused by very minute particles of wood 
scattered in the indentations of the elytra and thorax. The brilliancy of their ap- 
pearance is increased by raised lines and patches on the thorax and elytra, which 
are polished and show off against the remaining surface as work of burnished metal 
does against a grained or frosted ground. This beetle is comparatively rare, but 
perhaps as common in this locality as in most parts of the country. 
7. The tooth-legged buprestid. 
Chrysobothris dentipes (Germar). 
Though usually occurring in oak trees, occasionally living under the bark of the 
white pine, where it makes a flat, shallow burrow, sometimes half an inch broad and 
ending in an oval cell, in which the larva occurs in autumn, winter, and early spring. 
We have already noticed this Buprestid among oak borers. We have 
found, May 20, at Providence, R. I., the dead beetle in its burrow under 
the bark of a white pine stump. 
8. Harris's buprestis. 
Chrysobothris harr'mi Hentz. 
Order Coleoptera; family Buprestid^:. 
Appearing on the trees in May and becoming 
most common about the middle of June, a small 
beetle 0.32 long, of a brilliant blue-green color 
with black antenna' and feet, and in the male 
the sides of the thorax and the thighs copper- 
colored, its surface punctured, with a groove on 
the middle of the thorax and two indentations 
near the base of each wing-cover, slightly sepa- 
rated by a raised line, the inner one running into 
a groove which extends along the suture to its 
tip. Its larva living under the bark of young 
trees and small limbs. (Fitch.)
