•1^2 LEPIDOPTERA. 



Larva, " greyish-brown with a white dorsal line. It has 

 sixty spines, four on the first and last segments " (of the 

 body ?) " and six on each of the others ; those of the first two 

 are shorter than the rest, the central being the longest. Feeds 

 solitarily on Viola tricolor and Onohrychis in May and August." 

 (Lang.) 



But Kirby says : '• Blackish-grey, with a whitish stripe 

 on the back, and brownish-yellow lines on the sides. The 

 spines are short and brick-red." These two descriptions 

 seem to be rather complementary to each other than contra- 

 dictory. 



Pupa, " grey anteriorly, green posteriorly, with gold spots." 

 (Lang.) 



No description of either larva or pupa appears ever to have 

 been made here ; indeed, with one single — and doubtful — 

 exception, there is no record of the finding of either in these 

 islands. The exception is this: in the Zoologist for 1862, 

 Mr. W. Gaze (who many years ago collected with much 

 assiduity and success at Burwell Fen, Newmarket, and other 

 Cambridgeshire and Suffolk localities), wrote, that on first 

 going to Sudbury he called upon Mr. Barwick, a bird-stuffer, 

 who told him that on one of his visits to Assington Thickets, 

 in that neighbourhood, he had found a caterpillar, suspended by 

 the tail to a branch of hazel, which he left undisturbed till his 

 next visit, when it was changed into a chrysalis, which he 

 took home, and which in a short time produced a fine speci- 

 men of A. Lcdhonia. Mr. Gaze found that he was fully 

 acquainted with the species, and therefore believed this 

 statement, and also that Mr. Barwick's son had taken two of 

 the butterflies in the same place. As our only record, this 

 may be worth preserving. There is no doubt whatever that 

 Mr. Gaze himself took the insect in the same district. The 

 difficulty of finding larv^ of even the common species of this 

 group is so great that it may readily be supposed that larvae of 

 this occur in this country every year without being noticed, yet
