680 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



of the thorax has in its middle a well marked, elevated, smooth spot, which is ohlong 

 aud placed obliquely, with 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, resembling those of the preceding species, though on a partic- 

 ular examination several differences will be noticed. (Fitch.) 



This insect has also been found by Dr. Le Conte, at Sacramento, Cal. 



6. Chalcophora foriis Le Conte. 



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 fortis, a remarkable fine beetle, varying from one 

 to one and two- tenths inches in length, aud 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 aud elytra, which 

 are polished and show off against the I'emaining 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. 



Chrysobothria 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 harrisii 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 antennaj and feet, and in the male 

 the sides of the thorax aud the thighs copper- 

 colored, its surface punctured, with a groove on 

 ♦he 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
