BANKIA BANKIANA. 95 



tinue my observations until the end of the month, 

 when the larvae reached fall growth. 



I kept my pupae alive through the winter, but sup- 

 pose I mismanaged them during the month of May, 

 1883, by keeping them too much exposed to rain, as I 

 bred only one specimen, a male, on the 29th of June. 



The egg of B. banhiana is globular in shape, with a 

 slight depression at the base, about one-thirty-fifth of 

 an inch in width, and one-fiftieth of an inch in height, 

 with about thirty-four shallow ribs, and with shallower 

 transverse reticulations ; the central space in the top is 

 flat with large shallow reticulations ; the shell has a 

 pearly sheen ; when first laid, it was said to be of a 

 dull whitish, having the faintest greenish tinge, and 

 then gradually turned to a pale greenish-yellow. 



When first hatched the larva has the ventral legs 

 developed on the ninth and tenth segments, and a 

 small undeveloped pair on the eighth; it is of pale 

 yellowish-green colour, with very fine black dots and 

 hairs. After feeding a few hours the interior became 

 deeply tinged with dark green, which showed strongly 

 through the clear skin, especially in the middle of the 

 body ; when eight days old the skin became less clear, 

 and of a uniform light yellowish -green with blackish 

 tubercular dots. 



In twelve or thirteen days they moulted the first 

 time, and became less transparent than before ; and 

 after the second moult, in five or six days' time, they 

 were long and slender, and of a more opaque velvety 

 green, and faintly showed subdorsal lines of paler green. 



After another week the third moult occurred, when 

 the ground-colour was a little fresher than before, the 

 head very pale green, and a dorsal line of darker green 

 than the ground showed faintly here and there ; the 

 subdorsal lines were whitish -yellow, and also the seg- 

 mental divisions, while the length had increased to 

 seven and a half lines. 



The fourth moult occurred on the 14th of July, and 

 by the next day they had become nine lines long, and
