An analysis of this shows that certainly five species and doubt- 
fully one hybernate in the egg; twenty-eight and doubtfully 
eleven in the larva; eleven in the pupa; and eight in the imago; 
whilst the state in which one (Lycena Acis) passes the winter is 
altogether unknown. 
Pieris crategi departs from the habits of its congeners by 
hybernating gregariously as a larva. 
Colias Edusa and C. Hyale.—The information as to hyberna- 
tion in these two closely allied species is involved. See Kntom. 
xi., 60, 139. 
Satyrus Egeria.—In the first record of the life-history of this 
species Newman says that it hybernates in the penultimate or 
pupa state, but this is altered (? corrected) in ‘ British Butter- 
flies,’ on what authority or for what reason we are not told. 
At Entom. iii., 217, we have—‘ The larve are full fed by the 
end of September..... Early in October the larva spins a 
slight silken covering on a stalk, stem, or blade of grass, and, 
suspending itself therefrom by the anal claspers, is changed to 
an obese pupa..... In this state it remains throughout the 
winter, the butterfly appearing on the wing from the 10th to the 
20th of the following April.” At Brit. But., p. 86, we have— 
“The caterpillars hybernate early, and are full fed by the end of 
the following March.’ From present information the earlier 
account appears to be correct. 
S. Megera.—Two or three continental authors say this species 
‘iiber-wintert’ asa pupa. ‘This agrees with the present idea as to 
its near ally. The genus Pararge includes P. Mera, P. Hera, 
P. Megera, P. Egeria, &c. Professor Zeller says that in 1875, 
in the Albula Pass, he found P. Hiera as early as 24th May, and
