The Jarra.—The general color of the larva is a peculiar olive or greenish browii, more or less variable, finely lined with dark gray and brown, and this as well as other species of the genus which will be discussed are all ornamented on the upper surface with a double row of triangular, velvety-black, sometimes greenish, spots, which give them a striking appearance. The larvse are in fact so peculiarly marked that it is not at all difficult to separate this genus from any other conuuon genus of the same family occurring in the Eastern States. The larva of this species may be distinguished in all stages, except the final stage, by the greater number of these dorsal black spots and the lack of striation so visible in the other two. The bod}^ is cylin- drical and smooth; the head is small and polished black or dark brown in front, shading off into lighter brown at the posterior end and at the sides, with the frontal triangle margined with white. The thoracic plate is dull brown or blackish with the.
