inside, and there remained until the morning of the 

 18th, when it was out and feeding on a flower of 

 purple clover. On splitting up the stem I found 

 therein the cast-off skin (the eighth, H. T. S.). 



On the 23rd it again fixed itself to moult (the ninth, 

 H. T. S.), and accomplished the operation by the 

 morning of the 27th. The black V's were now dis- 

 tinct, the tubercles no longer dark, the yellow ochre 

 dorsal line quite bright. It fed well on flowers of 

 Trifolium jpratense and reopens until June 3rd, when it 

 ceased to feed, and on the 4th took up its position on 

 a dry stem placed for it, and began very deliberately 

 to construct its case of two side wing-like pieces of 

 silk, covering them with portions gnawed off from the 

 stem ; these by the evening of the 5th seemed to be 

 complete, and by night the larva was joining them 

 together from within. By the next morning, June 

 6th, the larva was enclosed, and the structure appeared 

 complete. (W. B., Note Book III, 296.) 



[Surprise is expressed at this larva moulting the 

 sixth time, but no surprise seems to have been caused 

 by its moulting three times after the sixth moult ! — 

 H. T. S.] 



On October 29th, 1882, Mr. W. E. Jeffrey sent me 

 a few eggs laid by a bred female, which had paired in 

 captivity. They were laid on a dry stalk by the side 

 of a cocoon from which one of the moths had emerged, 

 and adhered to the side of a little hollow channel so 

 as not readily to be seen. 



The shape of the egg is round and slightly flattened, 

 having a central depression on the upper surface. It 

 is finely ribbed and reticulated, white when first laid, 

 but afterwards became of a more creamy tint, and 

 having within the central hollow in the top of the egg 

 a ring of brown atoms. 



On November 4th I described a larva of this species, 



then nine-sixteenths of an inch in length stoutish, plump, 



with three rows of prominent tubercular warts, the 



upper or subdorsal row the largest, the next row the 



vol. in. 4
