The prebasilar fold is connate with the basilar segment, the suture is generally, however, well marked, existing as a deep groove. The cephalic segment is slightly emarginate between the antennæ. The labial teeth vary from 8—10 in number; there will sometimes be four on one side and five on the other, the external tooth apparently being the missing one. The antennæ are 25-jointed. Out of nearly a hundred specimens that I have examined, only two or three had one or two supernumerary joints developed. The scuta are polished, generally minutely and sparsely punctate, often obscurely bicarinate, the posterior with their lateral margins elevated. The last pair of legs are rather robust, with the basal joint longer than the tibial. The scuto-episcutal sutures are apparent, the sterno-episternal very well marked. Length 5½ inches.
