the mouth thau near the crown ; the segments of the body- 

 well divided and plump, each crossed by three wrinkles, of 

 which the middle one is the deepest ; prolegs slender, the 

 anal pair stretched out behind. Head whity-brown, having 

 a few light brown freckles ; ocelli black ; dorsal region 

 broadly delicate light opaque cream-colour, divided by a 

 narrow dorsal stripe of rich and very deep translucent green, 

 narrower at each end ; the pale cream-colour extends lower 

 down the side of the hinder half than on the front half of 

 each segment, and near the lower margin of this colour is a 

 fine line of translucent yellowish-green, a little interrupted 

 toward the end of some of the middle segments ; under this 

 is a stripe of translucent green broadest on the front half of 

 each segment, and below on the anterior segments a stripe 

 of lighter semitransparent green, which melts away into a 

 still lighter watery opalescent green on the legs and under- 

 surface ; raised dots inconspicuous but having each a small 

 central green dot ; spiracles minute, ringed with brownish- 

 black ; whole surface of the skin glossy. 



When fall fed it becomes almost uniformly j-ellow.

August and September upon Solidrii/n rirgaurea (golden- 

 rod). Abroad reported to feed also upon Bellidiastrum 

 Mischelii. Feeding on the underside of one of the lower- 

 most leaves of the plant, in a slight whitish web. 



Pupa moderately stout, with well developed thorax, and 

 long wing-covers, the abdomen tapering to a prolonged 

 blunt anal point ; rather warm dark brown, darkest on 

 the thorax and anal point ; surface of the wing-covers and 

 lower rings of the abdomen shining. Between leaves, or in 

 a convenient corner, within a semi-opaque whitish silken 

 outer cocoon of strong texture, three-quarters of an inch long, 

 in which is a series of open-work threads, forming a kind of 

 loose hammock. In this the larva passes the winter un- 

 changed, and the pupa state is assumed in the spring or early
