46 METAMORPHOSES OF 



skin. A specimen in my possession was Latched on 25tli 

 February, 1878. On March 3rd there was a change of skin, 

 and on March 14th another. I was not able to determine 

 any other changes, and the caterpillar was full-fed on April 

 3rd. After the second (or third ?) change, the larva becomes 

 covered with a white powder, that rubs off when touched, and 

 the whole skin becomes finally of a dull white colour. 



The caterpillar remains withip the leaf during the day, 

 and only comes out to feed at night. When anno,yed by the 

 approach of any insect, it has a curious habit of wagging its 

 head and thorax from side to side, and sometimes round and 

 round in a circle, striking its head against the sides of its 

 house. The noise thus made is considerable. (See fig. 11, 

 plate IV.)

Pupa. \ 28, 1878 = 25 days. 



The pupa is of a pale bluish green, and is covered with 

 the white mealy powder. It changes within the leaf, and 

 suspends itself by the "tail" and a band round the thorax, 

 lying on its back in a more or less horizontal position. 



Imago, a, h. 



The specimen that was full-fed on April 3rd appeared as a 

 perfect insect on April 28th, giving a dormant period of 

 25 days. 



At the end of June, I found other caterpillars full-fed, the 

 butterflies of which did not appear till the end of September.
