The scuto-epi scuta] sutures are very distinct, as arc also the sterno-episternal. The scuta 

 gen< rally are quite smooth. The body of each of the specimens is subcylindrical. I was 

 at first disposed to consider these as the males of the following species, but it seems most 

 probable that they are distinct. The principal differences are found, first, in the size of 

 the cephalic segment and length of antennae; second, in the punctations of the head; and 

 finally, in the number of segments and robustness of body. Length, 2 inches.

Orange, rather robust; dorsal median line double, black, here and there obsolete, reaching to the penultimate 

 segment; head rather large, lightly punctate; basal segment short; antenna' sparsely pilose; labium deep orange, 

 somewhat convex, sparselj lightly punctate, medianly strongly canaliculate, anteriorly emarginate; mandibles not 

 denticulate; scuto-episculal sutures rather distinct; feet on each side 53 ; ventral surface with a single, obsolete, 

 black, median line; sterna impressed with sutures and a median depression.

The cephalic segment has the sides moderately arched, with the anterior angles very 

 strongly rounded. The dorsal median line is entirely wanting on the anterior portion of 

 the body. The feel generally are without any hairs, but there are a few on some of them. 

 There are two specimens in the Museum of the Academy, collected in Georgia by Dr. 

 J. L. Le Conte.
