118 [October, 



commenced laying, and deposited about forty or more eggs. The weather again 

 becoming dull, there were no additions till the 18th, when on fresh plants there 

 were distributed another large batch of eggs ; and the following day the insect 

 expired, after depositing the final egg on a spray of Lotus corniculatus, placed with 

 the clover as an experiment. 



The eggs were oval, but very sharply pointed at each end, and were laid on 

 the upper surfaces of the leaves in an upright position, standing on end. They 

 were shining, and at first whitish-yellow, rapidly turning darker yellow, changing 

 by the fourth or fifth day to reddish, and in ten days to pink. At that time being 

 obliged to leave home, I had not the satisfaction of seeing the young larvte when 

 first hatched ; but reports of their progress were duly sent to me, whereby I 

 became aware of their beginning to hatch out on the 24th of June. The young 

 larvae were at first of a pale brown, and afterwards dull green ; some were bluish- 

 green, and all with a line of whitish along the spiracles, then and afterwards 

 assimilating well with the clover, of which they ate voraciously ; and probably, 

 during my absence, the supply of food had not been equal to the demand, for when 

 I saw them on 6th of July, their numbers had greatly decreased, and the survivors 

 were clustering on the bare stems of the plants they had stripped in the course of 

 the day. 



From that time they were abundantly supplied with fresh food, and though 

 their progress seemed satisfactory, it soon became evident that they had not been 

 able to recover the check sustained when young ; for they began to suspend them- 

 selves from July 16th, and change to pupae before attaining the size I had hoped 

 for. The first perfect insect came forth on the 6th of August, and the others 

 followed during about a week. They were most lovely examples of colour, but 

 smaller than ordinary captured specimens. 



After the young larvge became green, they so remained through all their 

 subsequent moultiugs, and no variety worth mention occurred in the brood. Their 

 habits were rather sluggish, especially as they matured. The size attained by the 

 largest was little more than one inch and a quarter in length, moderately stout, of 

 nearly equal size throughout, rounded above, and rather flattened beneath ; the 

 head globular, and rather smaller than the 2nd segment. The segments sub- 

 divided by transverse wrinkles or folds into six portions, the second portion the 

 widest. 



The colour was a deep, dull grass-green, the dulness being caused by their 

 being irrorated with excessively minute black points, and each point emitting a very 

 short fine hair, added a velvety appearance to the surface of both head and body. 



In some examples, a darker dorsal pulsating streak was visible, though in 

 general hardly noticeable. 



It was adorned with a whitish or else a yellow spiracular stripe, which was 

 further embellished on each segment by a pink or red blotch in the middle of it, 

 and a black spot immediately under it, while a little in advance of the red was seen 

 the oval whitish shining spiracle. The legs and ventral surface similar to the 

 back. 



The pupa was attached by the tail, and with a cincture of silk thi'ead around 

 it close below the thorax, after the manner of the Pieridi ; the head was generally 

 upwards, though in some cases a horizontal position, or nearly so, was chosen.
