THE LAVINIA BUTTERFLY. 293 



those of the preceding species. The butterflies appear in 

 August and September. 



Fig. 119 



Cynthia Lavinia,* Fab. Lavinia Butterfly. 



Wings dark brown above, each with a large and a small 

 eye-like spot on both sides ; the fore wings with two orange- 

 red spots near the middle of the front margin, and a large 

 whitish band enclosing the hinder eye-like spots j hind wings 

 with a reddish band near the hind margin. 



Expands from 2 to 2\ inches. 



The caterpillar is said to be blackish and dotted with 

 white, with the belly and legs tawny, and two white lines on 

 each side, the uppermost one of which is spotted with tawny 

 orange ; the spines (of which there are two short ones on the 

 head, besides those on the body) are black and branched. 

 According to Mr. Abbot, it lives on the Canada snap-dragon 

 (Antirrhinum Canadense), and remains in the chrysalis state 

 sixteen days. The chrysalis resembles in form that of the 

 two preceding species, but is said to be destitute of metal- 

 lic spots. I took one of these butterflies in a meadow in 

 Milton, on the 19th of August, 1827, and have never met 

 with it since in this State. It is very common in the South- 

 ern States throughout the whole of the summer. 



* Dr. Boisduval has described this insect under the specific name of Cauda.
