dniAv ovL'i" ;i part of the leaf, and thus form a little tent 

 beneath which the caterpillar lives. It devours the skin and 

 pul])y substance of the leaf, without touching the under 

 skin ; and, when it has exhausted the part under its tent, it 

 removes to another place, and makes a larger habitation as 

 before. Very young caterpillars, which are distingtiished by 

 their darker color as Avell as their inferior size from the 

 older ones, cover themselves with a very small portion of the 

 leaf, and are principally protected by means of the silken 

 tent. The full-grown caterpillar is about one inch and a 

 lialf long. Its head is black, its feet reddish, its body striped 

 with black and yellow interrupted lines, with about seven 

 branched spines, of a white color tipped with black, on each 

 seo-ment except the first, those on the fore part of the body 

 being moi'e obscure than the rest. These caterpillars fre- 

 quently suspend themselves to the plants on Avhich they live, 

 and they seldom wander far in search of a place wherein tc5 

 prepare for transformation. The chrysalis varies in color, 

 being most often brown, Avith golden or brassy spots on the 

 sides and back, sometimes entirely golden, and sometimes 

 white with a silvery lustre. The chrysalis state lasts from 

 eleven to fourteen days. The butterflies appear from the 

 middle to the end of July, and are found on the flowers of 

 thistles and other plants. I have also found them early in 

 jNIay, and as late as the month of August.

The caterpillars are found on the same plants as those of 

 the thistle butterfly, and particularly on the burdock and 

 cotton-thistle in June and July. INIr. Abbot says that they 

 live on a species of everlasting (^G-napJiaUiim j^oli/cejihidum') 

 also. They, as Avell as the chrysalids, are very mucli like
