 capitata. Body elliptical, convex above, flat beneath; segments distinct, 

 granulated minutely- color pale green ; a dorsal, dark gi'een line, two lateral 

 ones each side of it, midway between the dorsal lines and the sides, of a

 reddish line. First and last segments*3aler, reddish, the former liooding 

 and concealing the head in repose. Head very small, shining black, retrac-

 tish belly, with a transveree band of little threads; it Avas also fastened by 

 the tail. The other had formed its band, but was not metamorphosed.

 ends; very pale green, covered with long, erect, white hairs, spotted mi-

 tiguous towards the head, a lateral one each side, not extending quite to the 

 head. Wing thecte with about three, longitudinal, narrow bands of black- 

 ish, which, from the disposition of the wing cases, are oblique with respect 

 to the body, extending from the shoulders towards the back, or from below 

 upwards and backwards. The body is slightly contracted laterally before 

 the middle, bi-oadest behind the middle, more obtuse before than behind, 

 and the thorax projects slightly above. It is fastened by the tail, and by 

 several transverse threads, which are across the body before the middle.
