 shrubs in hot valleys. In the Bocche di Cattaro, at Castellastua, and 

 Prisdan.

 Spuzh.

SOME POINTS IN THE LIFE -HISTORY OF LYCMNA 



ABION. 



By The Honourable N. Chakles Eothschild. 



It is with no small interest that entomologists have read 

 Mr. Frohawk's interesting notes in the July number of this 

 journal on the life-history of Lyccena avion. There are, however, 

 several points which seem to require further elucidation, and 

 which it is hoped Mr. Frohawk will investigate and ultimately 

 settle. 



From Mr. Frohawk's latest notes it would appear that the 

 larva of L. avion only moults three times. This habit is un- 

 usual in the genus Lyccena, though present among several species' 

 of the genus Thecla. We do not think that Mr. Frohawk has 

 completely proved this point, though the evidence he submits 

 certainly points in this direction. 



On a former occasion Mr. Frohawk has recorded that a larva 

 of Lyccsna avion (when in the autumn it refused to eat any more 

 thyme) fed for many weeks upon a certain food he found appar- 

 ently suitable to it. This would lead one to believe that the 

 young larvre do not hybernate at once after quitting the thyme, 

 but are fed in the ants' nests ; and in connection with this it 

 may be mentioned that the larvae of the ant {Lasius flavus) live 

 through the winter, and are probably fed to some extent during 

 the winter by the ants in the nests, a fate possibly shared with 

 them by the young avion larvae. 



The larvae of avion, however, may not be fed by the ants, but 

 may feed on the vegetable refuse, &c., in the nest. 



Finally, why is it so difficult to find these larvae ? The 

 perfect insects are so numerous in North Cornwall that one 

 would imagine that the larvae must be quite common in their 

 habitat, and this Mr. Frohawk did not find to be the case. 

 Has the larva of Lyccena avion some curious method of con- 

 cealment ?
