106 P0LY0MMATUS (LYC^NA) ABION. 



teen, a few being laid on the stems and others on the 

 corolla of the flowers. No doubt there were more 

 eggs which I did not at the time detect. 



These eggs hatched on Thursday night, the 23rd of 

 June, i.e. on the seventh or eighth day after they were 

 laid, but I could not detect the young larvse. After a 

 careful inspection of the plants I telegraphed to Mr. 

 Hellins, to whom I had previously sent eleven eggs, 

 and his reply informed me that his were hatched and 

 that he could see one larva feeding. 



During the following week he reported them to be 

 looking like very small pinkish-brown maggots. . . . 



On the 17th of June, 1870, I received from Mr. 

 Herbert Marsden a pair of Lyccena Avion, said to have 

 been taken in cop. They were placed directly on Thymus 

 serpyllum, and the female laid nearly a dozen eggs, but 

 they proved to be infertile and soon shrivelled up. 



Another female kindly sent me by Mr. Marsden on 

 the 20th June, 1870, yielded no egg and died the 

 following day. (W. B., Note-Book II, 187.) 



POLYOMMATUS (LYCJ1NA) ADONIS. 



Plate XV, fig. 1. 



On the 30th of August, 1873, Mr. A. H. Jones most 

 kindly sent me two living females of this species 

 which he had just captured at Folkestone. These I 

 placed at once under gauze on a plant of Hippocrepis 

 comosa, and during the three or four days they 

 remained alive they laid about twenty eggs. The 

 larvae I believe hatched towards the end of September, 

 but as I kept them on a growing plant out of doors, I 

 could not see them hatching. In October I found the 

 leaflets of the vetch marked with little whitish dots ; 

 these were caused by the larvse tunnelling into the 

 underside, and eating out the inner surface for a small 

 space, leaving the upper skin untouched, which then 

 turned white.
