Southern States: differs from the rest by the impressed line not extending upon the 
front, by the coarser punctures of the thorax, by the deep transverse impression near the 
anterior margin, and by the obtusely carinate posterior angles. In one specimen there is 
a deep dorsal canal, which in the other is wanting.

4. A. torquatus, valde elongatus, ceneus. capite canaliculato viridi, occipite cupreo fortiter dense punctato, 
thorace medio purpuro, late canaliculato et biimpresso, lateribus cupreis subrectis oblique impressis, angulis pos-

serratis rotundatis. Long. -30. 
One specimen from Kentucky, Mr. J. Ph. Wild. Differs from A. arcuatus by the 
head less excavated, and the elytra more strongly granulate. The scutel is smooth, brassy, 
and not very strongly carinate: the elytra are narrowed regularly from the base nearly 
to the lip. The antenne are a little shorter than the head and thorax, green and strong.

5. A. fulgens, eneus, capite canaliculato viridi, occipite zneo fortiter dense punctato, thorace cupreo, la- 
teribus late rotundatis, profunde oblique impressis, medio canaliculato, et biimpresso, angulis posticis lonye cari- 
natis, elytris purpureis, lateribus sinuatis, fortius granulatis, apice serratis rotundatis. Long. -26. 
One specimen, Missouri, Mr. Schuster. Also differs from A. arcuatus by the same 
characters as the preceding, from which it is at once known by its smaller size and differ- 
ent form: the oblique impressions of the thorax meet at the middle. 
A specimen from Illinois entirely of a golden color appears to be a variety of this 
species. 
6. A. obliquus, aneus, capite modice punctato fere glabro canaliculato, thorace rugose punctato, dorso ca- 
naliculato, lateribus late rotundatis, profunde oblique impressis, angulis posticis longe carinatis, elytris obscuriori- 
bus, dense subtilius granulatis, apice serrulatis obtusius rotundatis.. Lone. -32.
