Rh scuto-episcutal and sterno-episternal sutures are very distinct, as well as those between the primitive sterna. I have found this species around Philadelphia, although not very abundantly. They appear to affect the inner bark or liber of decaying logs, especially that of the locust (Robinia pseadacacia, L.) I have, however, occasionally observed them under stones. It may possibly be Geophilus attenuatus, but that species can never be determined from Say's description.

The two black bands are somewhat irregular and so broad that it would, perhaps, be correct to describe the dorsum as black, with a single median and two longitudinal light stripes. The labium has three black dots on each side, but I suspect that these are not constant. The mandibles have, on their inner edge, the rudiments of a denticule. I have had great difficulty in determining the number of feet, but think that fifty pairs is very near the mark.

There is in the Museum of the Academy a single specimen, collected in Georgia by Dr. John Le Conte. The length is about an inch.
