104 MIANA EXPOLITA. 



its way down to the white portion close to the root 

 and, as Mr. Gardner observed, when one plant has 

 yielded its nourishment the larva migrates to another ; 

 and of this habit he had good evidence in some plants 

 he found ravaged and deserted by their former 

 tenants. 



The egg was noted as being of globular shape, with 

 soft glistening shell, scarcely showing traces of a sort 

 of pitting all over ; in colour a very pale straw- 

 yellow. 



The newly hatched larva was of the regular Miana 

 form, stoutest at third segment, whitish in colour, 

 shining, with the head black, a dark plate on second 

 segment, the usual dots very small and distinct, but 

 dark in colour. 



In captivity about the last week in October, before 

 hibernation, the larva was nearly or quite five-six- 

 teenths of an inch long, of the true Miana figure, 

 stoutest at the third and fourth segments, tapering a 

 little behind ; the head, smaller than the second, is flat- 

 tened and wedge-shaped towards the front, and of 

 reddish-brown colour, darker brown at the mouth ; a 

 broad shining semi-transparent plate on the second 

 segment of the same colour as the back, which is 

 lightish orange-brown, having a dorsal line of pale 

 orange-ochreous, with two short transverse bars about 

 the middle of each segment ; the subdorsal marking 

 of the same pale colour is broadish and bounded below 

 by the light orange-brown of the side, from which an 

 upward curved streak intersects the marking at the 

 first subdividing wrinkle, and two shorter curves 

 follow without much intersection ; the black spiracle 

 at the lower edge is followed by the pale orange- 

 ochreous of the belly ; a pale shining plate is on the 

 anal segment. 



After hibernation, at the end of April, the larva is 

 nearly half an inch long, rather slender but still 

 thickest at the thoracic segments ; the design and 

 colouring of the back and sides are much the same as
