inch long, with a large shining black head, and a white 

 body tinged with yellowish brown, this tinge being more 

 apparent towards the posterior part. 



The full-grown larva is of an oval outline ; the head 

 not large in proportion to the size of the body, but 

 prominent and much larger than the second segment; 

 it is of a dull reddish-brown color, edged with black on 

 the hinder part, and clothed with minute whitish hairs. 

 The body is dull brownish green, with hairs similar to 

 those on the head ; a dorsal line and numerous dots over 

 the surface of the body are of a darker shade. Joint 2 

 is pale whitish, with a line of brownish black across the 

 top. The last joints are paler than the rest, and the 

 under side of the body is paler than the upper. 



So far as known, there is only one brood in a season, 

 and the butterflies are on the wing in June and July.
