canary-yellow and rest of segments dark-yellow. Thoracic legs 
canary-yellow, pro-legs dark-yellow, flat and thick. Length 
13 inch. Plate XXV, fig. a. 
Pupa.—Sub-cylindrical, stout. Dark chestnut-brown to 
almost black. Black ventrally. Segmental bands orange, as 
also is front of thorax. Wing covers, eyes, antenne and legs 
well marked on outer covering. Stigmata black, with a

The moth of which descriptions of both male and female are 
given by Hampson in the Fauna is a large, stout, striking- 
looking insect with a white thorax and greyish mottled wings 
(see figure in plate XXV). Hampson gives the wing expanse in 
the ¢ as varying from 98-128 millim., that of the ? being given 
as 180 millims. The specimens obtained by me this year show 
_ that there is a very much greater variation in size in both sexes, 
The following dimensions of 32 moths, all taken from the same 
tree, are, I think, well worthy of being placed upon record :—
