REVISION OP THE BUPRESTIDyE OP THE UNITED STATES. 
Middle States, Canada, and Lake Superior. Varies in brilliancy of colour; the second 
synonym belongs to the dull-coloured variety. The male is narrower than the female, and 
has the tip of the abdoman more distinctly truncate, or rather, more broadly rounded. 
I cannot adopt the views of those authors who consider this species as B. aurulenta 
Linn. The description (Syst. Nat. 1, GG1) makes no mention of the elytral costa?, and 
applies more nearly to A. d e c o r a than to the present. In this state of confusion the 
name should be either applied to that species, or dropped entirely.

Oregon and Washington Territories, abundant. The male is a little narrower than the 
female, but the tip of the abdomen is subtruncate in both. 
19. A. radians Lee. Proc. Acad. Nat. Sc. 7, 17; Pac. R. R. Reports, 47th Par. Ins. 44. 
One specimen, Oregon, Dr. Cooper. Shaped like the male of A. 1 a u t a, but known by 
the very hairy front and prosternum. The tip of the abdomen is subtruncate.

One specimen, Oregon, Dr. Cooper. Broader even than the female of A. 1 a u t a, with 
intermediate elevated costa? on the elytra; the tip of the latter is distinctly bidentate. 
The abdomen is less strongly punctured, and scarcely truncate.

Middle and Southern States, not rare. The tip of the abdomen is truncate, subsinuate 
and bidentate in the male, subtruncate in the female. 
22. A. ultramarina. Buprestis ultramarina Say, Trans. Am. Phil. Soc. 6, 160. 
One female, Georgia. Say’s description was made only from the elytra, but the species 
I refer to under this name, is of a broader form than A. decora, with the intervals of the 
elytra less irregularly punctured, especially towards the suture, with the tips rounded, or 
hardly truncate, not bidentate as in that species. The abdomen is broadly rounded at the 
apex.

Southern States, rare. The tip of the abdomen is truncate and subsinuate in the male, 
broadly rounded in the female.
