1873.] 43 



yew, in the three followhig years, and from one of them I was able to obtain a moth, 

 the larva pupating in a folded hawthorn leaf after spinning the edges of the leaf 

 closely together. The date when this larva was full grown was May 23i'd, 1871 ; and 

 the moth appeared June 21st. — William: Bucklkr, Emsworth : June, 1873. 



Since the above was written, I append a brief mention of a fine example of this 

 larva which Mr. Harwood has just sent me : — It is a little over an inch in length ; 

 the third segment tumid, and beyond the fourth there is on each of the other seg- 

 ments a slight transverse swelling which bears the hinder pair of tubercular warts ; 

 it has but few simple filaments, all the rest bemg more or less branched. 



Its colour is brownish ochreous-green, and with fewer black marks than usual, 

 for which, in this instance, a rather deeper tint of the ground colour is substituted. 



This larva, when disturbed on its arrival, walked in a position like that of 

 Opldodes lunaris, as figured by Hiibner. — Id., June 11th, 1873. 



Supplementary notes on the Natural History of Lycana Alsus. — At p. 186 of 

 Vol. vii of this ilagazine, was published an account of the egg and larva of this 

 species. I am happy to be now able to add a description of the pupa. 



AU the larvse I had in 1870 died without pupating, so in 1872 Mr. Buckler 

 searched for more, and sent me about a dozen on July 30th. These I placed on a 

 flowering plant of Anthyllis vulneraria, which was set in a large flower pot, and 

 covered with leno ; they quickly, however, gave over feeding, and nearly all found 

 their way over the rim of the flower pot, and, under its shelter, fixed themselves on 

 a webbing of silk spun on the leno, just above the string, which fastened it roimd the 

 f)ot ; and I believe that if I could have allowed them to remain undisturbed, they 

 would not have moved again. But as they were kept outdoors, in order that they 

 might be subject to the changes of temperature and weather as in nature, before 

 very long, snails and slugs had eaten holes in the leno covering, through which came 

 prying ants and spiders ; an invasion which necessitated a renewal of the covering, 

 and a disturbance of the larvse ; and this being repeated more than once, caused, 

 I believe, the death of most of my stock. At last, however, after waiting ten months, 

 I was, on June 3rd, 1873, rewarded with the sight of a newly turned pupa, which 

 I now describe as it appeared after the colours had settled. 



Length rather over a quarter of an inch ; width less than one-eighth of an inch ; 

 in figure, when viewed in front, a long ellipse ; but sideways, the rather prominent 

 head, the rounded thorax, and swelling abdomen, with its blunt tip curved under, 

 give a much more irregular outline ; the wing-cases straight, long in proportion, 

 well developed, but rounded off at the angles ; the upper or back surface sparsely 

 set with fine hairs. 



The colour a dirty whitish-grey, approaching di-ab, more gi'cyish on the head 

 and thorax, paler on the abdomen ; there is an interrupted dorsal stripe of black, 

 and on either side a lateral row of short, oblique, black dashes ; the nervures 

 of the wings are well shown by the spaces between them being filled up with dark 

 grey ; the hairs arc whitish, and the whole surface is sprinkled with some minute 

 black dots. 



As I write, this pupa is changing colour from the development of the imago, 

 and I sec that in 1870 the perfect insects were laying eggs on Juuc 17th; sii the
