PEMPELIA CAUNELLA. 263 



morning the larva had spun itself up in the ham- 

 mock. 



The remaining larva3 soon afterwards spun up in a 

 similar way, though the last two were as late as the 

 16th of August, amongst gathered food and in cap- 

 tivity ; for the fine plant had become utterly suffocated 

 and unable to sprout afresh by the binding of its parts 

 together with great quantities of web ; probably one 

 or two larvae escaped, as I picked up one astray at 

 some distance from the pot. 



I do not think that it is to be inferred that the 

 larvse are naturally gregarious, for, although in this 

 instance they were able to conform to circumstances, 

 I did not fail to witness a little testy and resentful 

 behaviour by one larva when intruded on by another. 

 They were lovers of sunshine, and whenever they felt 

 the genial rays, came forth to spin with increased 

 energy. 



Five moths in all were bred, on the 13th, 16th and 

 30th of September, and the 1st of October. 



The egg of Pempelia camella when first laid is 

 round, flab and scale-like, whitish, then turning 

 yellow, afterwards streaked with reddish, again 

 changing to fawn-colour and becoming convex above, 

 and, an hour or two before hatching, showing a dark 

 purplish spot on the upper surface. 



The larva on quitting the shell is of a pale drab 

 tint with darker dorsal line, and blackish head and 

 collar ; its pace is running rather than walking ; in 

 four days' time it shows traces of other lines besides 

 the dorsal one, and on the nineteenth day it is nearly 

 an eighth of an inch long, of pale pinkish-green tinted 

 body, with numerous dark brown lines along its 

 length, the head and collar dull black. 



After hibernation it is nearly three-sixteenths of an 

 inch long, slender, and marked as before with alter 

 nate lines, now of green and blackish, a design which 

 continues to be developed, the head and second 

 segment black, and for a time even the pair of legs of
