them small warty tubercles ; the hairs blackish, appa- 

 rently more numerous than before ; the belly flattened. 

 When this is seen by turning the larva over on its 

 back, the head can only be seen as though sunk in a 

 hood formed by the overlapping margin of the second 

 segment. 



By the 15th of September some had grown to be a 

 quarter of an inch long, and two individuals were 

 broadly marked with deep purplish rose-pink all round 

 the lateral margin, the dorsal line was also of the same 

 colour. (W. B., Note-Book III, 138.)

Plate XIY, fig. 1. 



In the spring of 1862 I had a few eggs laid by a 

 captured female on the foot- stalks of flowers of holly 

 (Ilex aquifolium) ; the larvae hatched during the last 

 two days of May, fed first on the flower-buds of the 

 holly, and afterwards on the young green berries, and 

 by June 29th, that is, in about thirty days, had changed 

 to pupae. 



I had been anxious to work out the question of a 

 second brood of this species, but as no butterfly ever 

 appeared from any of these pupae, my attempt at that 

 time came to an unsuccessful end. 



On the 20th of June, 1875, 1 received two full-grown 

 larvae, feeding on tender young leaves of holly ; they 

 had been taken by beating, a day or two previously, by 

 Mr. Gr. F. Mathew, R.N. ; one of them had already 

 ceased to feed and had changed colour ; the other was 

 still feeding well, and I watched it eating a large piece 

 out of a freshly gathered tender leaf. The next day 

 this also rapidly changed colour, and on June 25th and 

 26th, both successively became pupae. One fixed with 

 its head downwards on the upperside of a leaf, the 

 other with its head upwards on the underside. From
