has been suspended thirty-six hours, and emerges nine days there- 

 after. 



I have taken the hutterfl// the last of June. It is usually quite rare, 

 but on one occasion I met with a number of them, in a sheltered road- 

 way in a wood, on elevated ground, sporting in the bright sunlight, 

 with short and rapid flights. When it alights on a tree, it seldom re- 

 mains stationary, but continues walking over the leaves, opening and 

 folding its wings. 



LiMENITIS DISIPPUS, Godt. 



The larva has a marked I'esemblance to that of arthemis, and cannot 

 readily be distinguished from it, unless by actual comparison. The 

 green upon it varies from a pea-green to a darker shade, but is never 

 so dark as in (irfhemis. 



I have found the larva on the Gray Willow {Salix grisea^) in July. 

 Several willows which I examined during a walk, on the 28th July, 

 gave me each one larva or more, in different stages of maturity, from the 

 second molting, to full grown. Their position was at once revealed by 

 the twig upon which they had fed — usually the top one — having been 

 entirely defoliated, from its tip about eighteen inches downward, leav- 

 ing only the footstalks of the leaves remaining. I have also taken it 

 on the White Poplar (Popidm tremuloides), to the number of five on 

 one small bush. 



The chrysalis resembles closely that of arthemia ; the dorsal projec- 

 tion is smaller and more elliptical in outline ; the depression between 

 it and the thoracic carination, deeper; head-case nearly square in front. 



The hutterflij emerges early in August, after eight or nine days in 

 chrysalis. I have also captured it early in May, appearing as if it had 

 survived the winter. 



Pyrameis huntera, Sm. Abb. 



Larva, head and first segment without spines ; body with rows of 

 black branching spines — brown, with delicately lined bands (yellow, 

 Abbott, black, Fab.) on the anterior of each segment; two dorsal rows 

 of seven white (white and red alternately, Abbott) dots. Changed to 

 chrysalis Sept. 3rd. 



Chrysalis, suspended by the tail, yellowish ; moderately angular ; 

 head-case, bifid, slightly projecting, and edged with brown above ;
