4 THE ENTOMOLOGIST. 
remarks that the snow was only just then melting, so that. the 
larva must have changed under the snow and the imago have 
been rapidly developed, or, ‘differing from Megera, the penulti- 
mate state was reached in the autumn. (Stett. Ent. Zeit. 
XXxvill., 307). 
Chortobius Pamphilus—Von Prittwitz says this species 
hybernates in the egg (see H. M. M. vi., 223). Newman says 
in the larva. Which is correct ? 
Thecla quercus.—With respect to this species the. Rev. J. 
Hellins very pertinently asks the following (EK. M. M. xiv., 112):— 
‘The sallow leaf would before long have fallen from the bush and 
decayed; and if the larva is not hatched till the spring, what 
meanwhile becomes of the egg ?” 
Polyommatus Phleas.—The only authority I can find for the 
hybernation of this very common species is Mr. Moncreaft’s 
- note at Entom. iii., 41. 
Lycena Agestis (Medon).—Newman says ‘egg, but it is 
given as ‘larva’ on Professor Zeller’s authority (Isis, 1840 and 
E. M. M. iv., 74). 
L. Alexis (Icarus).—Kaltenbach says this species hybernates, 
like many of its congeners, as a larva (‘ Pflanzen-feinde,’ p. 109). 
Newman gives it as doing so in the egg. There ought to be no 
question about so common a butterfly. 
Hesperia comma.—Rev. J. Hellins says (HK. M. M. vi., 222) 
that this species deposits its eggs in August, and they are not 
hatched till the following March or April.
