S. parva, Wood, Proc. A. N. 8., 1861, p. 10.

The antennæ are generally, but not invariably, without pubescence. The first segment of the body is the smallest, the third the next. The sutures between the true sterna and episterna are well marked, those between the scuta and episcuta barely traceable. The cephalic segment is slightly depressed. The dental lamina have their margins rounded in some specimens. The scuta are frequently bordered with very dark green posteriorly. The dorsum in some individuals has a dark central stripe, vanishing posteriorly. This is, without doubt, the species intended to be indicated by Mr. Say, although his description is exceedingly indefinite and scarcely agreeing with the facts. I have, however, seen one specimen with its posterior feet tipped with blue, and another in which the posterior margination was yellowish, as he describes them. Neither have I any doubt in referring Mr. Newport's S. punctiventris to this species, although the number and arrangement of the spines on the posterior feet differ somewhat from those given by that author. One specimen belonging to the Smithsonian (No. 329) approximates to his description. The types of S. parva are in the collection of the Academy of Natural Sciences, brought from the mountains of Georgia by Dr. Le Conte. Length 2 inches.
