which are not more than half an inch in length, the rest 

 having all died.— C. J. Biggs (October 17, 1877). 



Mr. W. H. Harwood had larvae this autumn, which all 

 died before changing. However, one was feeding as late as 

 December 21st. 



My own notes are as follows : — 



Wild specimens seen on June 6th, 7th, 8th, 9th, lOlh, 11th, 

 12th, 13th, 15th, 16lh, 17th, 18lh, 19th, 20th, 28th, 30th; 

 July 2nd, 3rd, 30th, 31st; every day in August but the 10th, 

 25th, 26th and 27th; September 1st, 7th, 10th, 11th, 17th, 

 I8th, 19th, 22nd, 26th; October 6th, 19th. Allowing for 

 absence from home and other causes this shows almost a 

 continuous occurrence from June 6th to October 19th; the 

 only break being through July. The first female I took on 

 June 6th 1 confined, with two others taken subsequently, 

 over growing plants of Trifolmm {var. spp.), Medicago 

 (var. spp.), and Lotus curniculatus. The first captured female, 

 only, laid eggs. These were deposited, as described in 

 Newman's ' British Butterflies' (p. 144, and see figure), on 

 the trefoil {Medicago lupulina), on June 8th, and numbered 

 upwards of two hundred. The eggs hatched on June 14th, 

 and the two first larvae fixed for changing on July 7th. This 

 operation was completed (visibly) by the 9th. The two first 

 imagos emerged on July 21st. The most accelerated meta- 

 morphosis thus occupied forty-three days from the egg-laying, 

 thirty-seven from hatching; and the most prolonged occupied 

 sixty-eight days from the egg-laying. 1 can speak to this 

 decidedly, as 1 had not a single dead pupa, neither did I have 

 a cripple emerge, or any semblance of a variety. The brood, 

 I am afraid, was kept much too natural for this. The record 

 of emergence is: — July 21st, two males; 22nd, one male; 

 23rd, five males; 24th, four males and three females; 25th, 

 five males and four females; 26th, one male and six females; 

 27tli, four males and twelve females ; 28th, two males and 

 six females; 29th, four males and three females; 30th, three 

 males and three females; 31st, five males and five females. 

 August 1st, four males and three females; 2nd, one male and 

 two females (fourteen pupae distributed) ; 3rd, two males and 

 one female (four pupa^ distributed) ; 4th, one male and two 

 females ; 5th, one male ; 6th, one male and two females ; 

 7th, one male; 8th, two males and two females; 9th, one 

 female; 11th, one female; 15th, one female. In all, forty- 

 nine males and fifty-seven females. On the 27lh July 1 put 

 some of these bred pairs under various cages in a lucerne
