One of the specimens has the last pair of legs very thick and long and vertically compressed. They are composed of eight joints, all of which are obconic except the last, which is very short and rapidly acuminate. This individual is probably the male. The other, the female, has the hindmost legs very slender, with the coxal joint proportionally very much larger than in the male.

In the single specimen the color is very light, but originally may possibly have been an orange. The body is almost destitute of polish. The epimeral plates are very large. I am indebted to Dr. J. L. Le Conte for the specimen, which he captured in the mountains of Georgia.
