EUBOLIA LTNEOLATA. 99 



and very slightly attenuated from the eleventh to the 

 anal segment. Skin tough, along the sides and at the 

 segmental divisions rather wrinkled. 



The ground colour is pale olive-green, at and on 

 each side the segmental divisions pink ; the head is 

 greenish-yellow, spotted with black. The dorsal line 

 is dark green, and there is a still darker and much 

 broader smoky stripe above the spiracles ; between 

 this stripe and the dorsal line are two faint waved 

 olive-brown lines. The ventral surface is bright 

 yellowish-green, with paler central stripe ; the seg- 

 mental divisions are sulphur-yellow. 



The larva3 went underground and changed to pupa 

 about the middle of June ; the latter is about a 

 quarter of an inch in length, smooth and shining ; 

 very dark brown, with the abdominal divisions pale 

 brown. (George T. Porritt, 17th October, 1872; 

 E.M.M., January, 1873, IX, 197.) 



The following account has been drawn up from 

 observation of many broods 5 kindly sent me from 

 different localities during a period of several years, 

 and touches on a few points which I do not remember 

 to have seen noticed elsewhere. 



The moth is noted as being on the wing in every 

 month from April to August, but I do not know that 

 there are more than two broods in the year; for the 

 first, May would be the month, early examples appear- 

 ing in April, and late ones in June ; and in like 

 manner the second brood would be seen in July and 

 August. In 1868 I had a spring brood of larvse, all 

 the moths from which appeared as a summer flight in 

 July, except one specimen, which remained over the 

 winter, and did not appear till the 20th of May, 1869. 



The egg and larva states of the two broods do not 

 differ much in duration ; the larvse come to hatching 

 from eight days to rather more than a fortnight after 

 the eggs are laid, and feed up in the course of from 

 four to six weeks, the speed of development in each 

 case depending on the character of the season ; but.
