206 REVISION OF THE BUPRESTID OF THE UNITED STATES. 
mer with a short occipital impressed line, the latter obsoletely channeled, wider than long, 
eradually narrowed from the base forwards, slightly rounded on the sides. Elytra purple 
black, with the basal margin golden green: they are ornamented with a large oblong spot 
at the base, extending one third the length, and nearly attaining the suture: it sometimes 
emits a slender external branch so as to enclose the humeral callus: just behind the middle 
is a transverse sinuous spot sometimes reaching the suture, and then connected with the 
third spot, which is near the tip. The strize are deep and slightly punctured: the intervals 
convex, smooth, with a few small scattered punctures, especially towards the base and 
sides: the tip is truncate and bidentate. The tip of the abdomen of the female is broadly 
and very slightly emarginate, with the angles distinct, though not prominent. The 
male is unknown.

Oregon and Washington Territories; Dr. J. G. Cooper, and Mr. George Gibbs. Allied

and more punctured, and the intervals narrower and more convex. The elytra are usu-

Not rare, especially in the northern portions of theAtlantic States; varies in colour from 
green to blue, and also in the size of the markings of the elytra. The tip of the abdomen 
of the female is truncate; in the male it is truncate and bisinuate: the anterior tibize are 
simple.

Kansas and Nebraska. In the male a broad yellow vitta extends from the anterior 
margin of the prosternum almost to the end of the first segment of the abdomen: the last 
seement of the latter is semicircularly emarginate, and has a small yellow spot each side 
about the middle. In the female the tip is feebly emarginate, without prominent angles.
