112 CARADRINA MORPHEUS. 



it could be kept in good condition, but the plant soon 

 died off, and then, amongst a variety of other food 

 supplied, sallow obtained the preference. Their pro- 

 gress was slow, and they delayed spinning until the 

 15th of October, when the first formed its cocoon in a 

 sallow leaf ; on the 18th two spun up in dock leaves ; 

 and on the 22nd one in sallow leaf ; and the last on 

 the 2nd of November, also in a sallow leaf. 



No earth was allowed them, in order that I might 

 be better able to observe their behaviour and inspect 

 their cocoons from time to time. These at first were 

 sufficiently clear when held between the light and the 

 eye to show the form of the larva within, but in a few 

 days their opacity increased and baffled observation. 

 However, towards the advent of spring I made myself 

 certain of their containing their inmates, and on the 

 11th of June, 1872, a female moth appeared. After 

 waiting a few days I opened the four remaining 

 cocoons, and found a pupa in one, and in each of the 

 others a shrivelled dead larva, and was thus confirmed 

 in my belief that they had all fed up in the autumn. 



The full-grown larva, when stretched out, is from 

 one inch to one inch and one eighth in length, of uni- 

 form and very moderate stoutness, the head the smallest 

 segment, and the thirteenth a little tapered ; it is 

 noticeable that the tubercular small warty dots bear 

 each an exceedingly fine and pointed hair, hardly to be 

 seen, in this respect very unlike the blunt bristles of 

 some of its congeners. In colour it is either a warm 

 brown or a greyish-brown, the sides being the part 

 rather deepest in tint ; the spiracular region, belly, and 

 legs of a paler tint of brown ; the head rather shining 

 brown, freckled with darker, and having a dark brown 

 streak down each lobe ; the second, third, and fourth 

 segments show but little markings, if any, of the dorsal 

 paler line, whilst on all the others it appears only in an 

 interrupted manner through a series of diamond shapes 

 of darker brown freckles, two joined end to end on 

 each segment, the anterior one very small, the other
