THE MYHIAl'ODA OF NORTH AMEKKJA. 



Deep orange, robust, beautifully polished J bead orange; cephalic segment small, sparsely subprofoundly punc- 

 tate; antennas short, pilose; mandibles very sparsely pilose, very indistinctly quadridentate, each with a single 

 rather large tooth (sometimes two); labium subprofoundly punctate, anteriorly emarginatc, inedianly canalicu- 

 late; feet compressed, on each side (in male?) 55.

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

 generally 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.

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 feet 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 Contc.
