in the centre, to which the anal hooks of the pupa 

 were attached in a horizontal position, the back of the 

 abdomen being so much curved round towards the 

 leaf as to imitate the upper two-thirds of the letter s. 



It had a deep depression on the back below the 

 thorax, and a square form towards the head ; the wing- 

 cases were thick, with prominent edges below ; the 

 segmental divisions of the abdomen well denned, and

 jecting points. 



The colour of the wing-cases, head and thorax, was 

 pitchy-black, with some reticulations of brownish-

The larvae began to hatch in about eleven or twelve 

 days, that is about June 20th, and were all out on the 

 22nd, and after breakfasting on their egg-shells, fed
