216 REVISION OF THE BUPRESTID OF THE UNITED STATES. 
I should be inclined to consider the differences as sexual, but that I have before me a 
large series of A. strigata in which no such variations are seen. 
b. Capite glabro, reticulato. 
6. A. inornata, latiuscula, depressa, nigro-eenea, thorace latitudine plus duplo breviore, postice paulo angus- 
tato, lateribus rotundatis, postice subsinuatis, et marginatis fortius reticulatim punctato, subgranulato profunde 
quadrifoveato, elytris dense rugose granulatis, fortius marginatis, parallelis postice angustatis et rotundatis. Long.

Buprestis inornata Randall, Bost. Journ. of Nat. His. 2, 4. 
One specimen from New York given me by Mr. John Akhurst. This species resembles 
in appearance A. fo veicollis, but is broader and smaller, with the thorax densely and 
strongly reticulated. It also differs from all the preceding species by the head being en- 
tirely glabrous, with the punctures more closely placed, and forming a reticulate surface: 
the central portion of these punctures both of the head and thorax is elevated, so that an 
appearance is produced intermediate between reticulation and granulation. According to 
Randall the impressions of the thorax are sometimes obsolete. 
B. Elytra subtiliter rugosa, viz obsolete granulata. 
7. A. cyanella, cyanea, vel purpurea, capite fortiter reticulato, thorace latitudine sesqui breviore, antrorsum 
subangustato, lateribus late rotundatis, reticulato, pone medium utrinque transversim oblique profunde impresso, 
elytris parallelis postice oblique rotundatis, subtiliter rugosis. Long. -17—-21.

Anthaxia scoriacea Mels. Proc. Acad. Nat. Se. 2, 148. 
Middle, Southern and Western States, rare. Of precisely the same form as the next, 
and differing only by the colour, and by the surface of the meshes of the net-work cover- 
ing the thorax being nearly smooth. The oblique impressions of the thorax are formed 
by the confluence of the two transverse ones; the anterior and interior of which nearly 
meet at the middle. The front is sometimes green. 
8. A. sub nea, nigro-zenea, opaca, elytris interdum cyanescentibus, capite thoraceque fortiter reticulatis, hoc 
subtiliter granulato, latitudine sesqui breviore, lateribus late rotundatis, pone medium utrinque oblique impresso, 
elytris parallelis postice oblique rotundatis, subtiliter rugosis, antennis viridieeneis. Long. -20—-25. 
Anthaxia viridicornis { Lap. & Gory, Mon. Bupr. 2, 19; tab. 5, fig. 25. 
Abundant in the Middle and Western States. Under the specific name quoted, Say 
has confounded several different insects, but in neither place where he uses it, is reference 
made to the form here under consideration. 
9. A. viridicornis cyaneo-nigra, opaca, fronte thoracisque lateribus fulgenti-cupreis, fortiter reticulatis, 
hoe subtiliter granulato, latitudine sesqui breviore, lateribus rotundatis, utrinque transversim impresso, elytris 
parallelis postice oblique rotundatis, subtiliter rugosis, antennis nigro-viridibus. Long. -20—-27. 
Buprestis viridicornis var. Say, Trans. Am. Phil. Soe. 4, 161.
