which they had stripped and deserted, gave sufficient proof 



of the voracity of these caterpillars. The chrysalis (Fig. 



123) is of a dark brown color, with large tawny spots 



rig. 123. around the pointed tubercles on the back. The 



butterflies come forth in eleven or twelve days 



after the insects have entered upon the chrysalis 



state, and this occurs in the beginning of July. 



A second brood of caterpillars is produced in 



August, and they pass through all their changes 



before winter. 



Vanessa J Album. The White J Buttei'fly. 



Wings pale tawny red above, each with a white spot be-- 

 tween two black ones near the outer angle on the front 

 margin ; the fore wings with a larger black spot on the mid- 

 dle of the front edge, and five smaller roundish black spots 

 near the middle of the wings ; hind wings with a silvery- 

 white character somewhat in the shape of the letter J in the 

 middle of the under side. 



Expands from 2i to 3 inches. 



The catei-pillar and chrysalis of this butterfly are un- 

 kno-wn to me. The butterfly probably survives the winter 

 like the Antiopa, for it has been observed late in the autumn, 

 and again early in the ensuing spring, sometimes in great 

 numbers ; but it is very inconstant in its appearance. It is 

 more common in New Hampshire than in Massachusetts. 



Vanessa Interrogationis, F. Semicolon Butterfly.^ (Fig. 124.) 



Wings on the upper side tawny orange, with brown spots 

 running together on the hinder part, and with black spots in 

 the middle ; hind wings in the male most often black above, 

 except at the base, and sometimes of this color in the other 

 sex also ; the edges and the tails glossed with reddish white ; 

 under side of the wings in some rust-red, in others marbled 

 with light and dark brown, glossed with reddish white, and
