REVISION OF THE BUPRESTIDAl OF THE UNITED STATES. 217 
Maryland, Mr. J. Ph. Wild. The sculpture is precisely that of the preceding, but the 
thorax isa little wider, and the impressions, (formed as usual of two on each side,) do not 
reach the base or posterior angles, but run to the sides; the posterior angles are also more 
obtuse. The head is bright coppery, with the occiput and sometimes a small frontal spot 
black. 
The type B. viridicornis Say, (Journ. Acad. Nat. Sc. 3, 163,) inhabits Missouri, 
and is described as having the head and thorax bright coppery, and the antenne green; 
body beneath brassy. It is probably a variety of the one here described. Of my speci- 
mens two are entirely blue black beneath, while the third is brassy; the elytra of the last 
mentioned specimen are black bronzed.

Middle and Western States. At first view resembles A. subenea, but on compa- 
rison, the thorax is found less rounded on the sides, the basal angles more rectangular, 
and the head more deeply punctured. The elytra are also slightly narrowed from the 
base, thus forming a transition to the following species. 
Il. A. quercata, opaca, capite fusco, macula annulari conchoidea viridizenea, fortiter reticulato, thorace la- 
titudine sesqui breviore, postice subangustato, lateribus late rotundatis oliyaceis, reticulato, utrinque pone medium 
transversim impresso, vitta dorsali latissima fusca, elytris fere parallelis, postice oblique rotundatis, subtiliter ru- 
gosis, olivaceis, margine vittaque obliqua integra suturam ad medium attingente fuscis; subtus viridi-nigra, abdo- 
minis margine laterali viridiaureo. Long. -16—-23. 
Variat tota viridi-nigra, abdominis lateribus solis viridizeneis.

Middle and Southern States, abundant. Varies in colour and size, but appears to be 
always a little broader than the next species, with the sides of the thorax a little more 
rounded and the elytra less distinctly narrowed from the base. 
12. A. cuneiformis, opaca, capite viridizeneo, fortiter reticulato, thorace latitudine sesqui breviore, postice sub- 
angustato, lateribus antice paulo rotundatis viridibus, vitta dorsali fusca seepe obsoleta, reticulato, postice utrinque 
transversim impresso, elytris a basi sensim angustatis, apice oblique rotundatis, viridibus margine et sutura pone 
medium fuscescentibus, subtiliter rugosis; subtus viridi-nigra, abdominis margine laterali parapleurisque viridieneis.
