4.38 HYBERNATION OF INSECTS. 
luable remarks on the present subject*, says that he never 
found or heard of any entomologist finding a hyber- 
nating individual of the common cockchafer (Melolontha 
vulgaris), or of the stag-beetle (Lucanus Cervus); and 
suggests that it is only those insects which exist but a 
short period as larve, as most of the tribe of Curculionidae, 
Coccinellide, &c., that survive the winter in the perfect 
state; while those which live more than one year in the 
larva state, as the species just mentioned, are deprived of 
this privilege. 
Towards ‘the close of autumn the whole insect world, 
particularly the tribe of beetles, isin motion. A general 
migration takes place: the various species quit their usual 
haunts, and betake themselves in search of secure hyber- 
nacula. Different species, however, do not select precise- 
ly the same time for making this change of abode. ‘Thus 
many Coccinelle, Cimices, and Muscide are found out of 
their winter quarters even after the commencement of 
frost ; while others, as Schmid has remarked, make good 
their retreat long before any severe cold has been felt: in 
fact, I am led to believe, from my own observations, that 
this is the case with the majority of coleopterous insects ; 
and that the days which they select for retiring to their 
hybernacula, are some of the warmest days of autumn, 
when they may be seen in great numbers alighting on 
walls, rails, path-ways, &c. and running into crevices and 
cracks, evidently in search of some object very different 
from those which ordinarily guide their movements. I 
have noticed this assemblage in different years, but more. 
particularly in the last autumn (1816). Walking on the
