begin to expand, when her labours cease ; for, as the 

 larvae can neither bear wet nor sunshine, they require 

 the protection afforded by the closed petals. The 

 eggs are hatching from the beginning to the end of 

 April, principally influenced by the variations of the 

 season ; if the weather be warm, they are matured in 

 five or six days. During this period the bud grows* 

 and the petals of their usual rosy colour, but instead 

 of expanding, they wither, and eventually turn to a 

 rusty brown, and on opening them, in place of the 

 germen and stamina, which have been consumed by a 

 single maggot, one finds rolling about in this globular 

 chamber a pupae, of a deep ferruginous colour, which 

 is very sensitive and restless when touched (fig. 4). 

 The maggots are curved, fleshy, and whitish, having 

 numerous segments and wrinkles, with a few short 

 hairs, but no legs ; the head is horny and black, and 

 furnished with small jaws (fig, 3). The exact time 

 they remain in the pupae state has not been ascer- 

 tained, but in about a month from the period when 

 the eggs are deposited, the weevils hatch, and eating 

 a hole through the dry petals, they disperse over the 

 tree, and feed upon the leaves during the remainder 

 of the summer. Like most of the Curculionidae when 

 approached, the apple-weevils contract their eggs and 

 fall down, so that it is difficult to detect and capture 

 them in any numbers, except whilst they are pairing,
