 feet was an interrupted fine black line. 



The ventral prolegs were broadly ringed with black 

 above, and their extremities tipped with black ; the 

 anterior legs black. (W. B., E.M.M. IV, 253.)

I received some eggs from the Rev. J. Hellins on 

 the 25th of June, 1882. The eggs were very large, 

 nearly globular (some were rather more oval), smooth- 

 shelled, of a very delicate greenish tint and glistening 

 like so many pearls. A few days before they hatched 

 there could be seen through the shell, what looked 

 like two air-bubbles, and a few hours before hatching 

 the form of this embryo larva could just be discerned 

 of the same colour as the shell, though the latter when 

 the larva has left it is quite clear like glass. 



On the 3rd of July these eggs hatched, the larvse 

 eating out a hole at the side for their escape ; in some 

 instances three-fourths of the eggshells were eaten, 

 whilst in others it was only the small portion of the 

 shell, the removal of which furnished the hole of exit, 

 that was devoured ; the newly-hatched larvae were of 

 the tenderest tint of green, with very long caudal horns 

 projecting from the twelfth segment. 



One larva that had eaten the greater part of its egg- 

 shell waited by the remains of the shell apparently to 

 digest its meal, and in the meantime its long tail began 

 to wither at the end for more than half its length, and 

 then shrivelled and turned blackish at the point of the 

 round portion, which eventually proved to be the tip 

 of the caudal horn, all beyond falling away — but with 

 the other larvse their long tails remained without 

 increasing in length, whilst their bodies rapidly grow- 

 ing made the tails appear more proportionate in length.
