between lepidopterous larve and their swrrowndings. 341 
G. Two of the 3 lightest larve, with black twigs.—Both 
larvee were healthy and irritable; they had evidently eaten. 
One was resting on the hawthorn branch and 1 on a 
black twig. They still remained very light, like that 
described above (F), and were quite unaffected by their 
dark surroundings during hybernation. 
H. Zhe 2 larve—the brownish one and that with bluish- 
white spots—with lichen-covered sticks,—It is improbable 
that anything had been eaten, and these larve did not 
appear to have emerged from hybernation. The one with 
bluish-grey marks was upon a lichen-covered stick: it was 
shrunken, and it appeared doubtful whether it would 
survive. The other was still attached to its foot-hold on 
the hawthorn branch, and had evidently not moved during 
the winter. It was very lichen-like, and entirely unchanged 
by its winter environment. 
III. tHe 11 QUERCIFOLIA LARVA WITH BROWN 
BRAMBLE-STEMS BEFORE HYBERNATION. 
I. Four of 7 uniformly brown larve, with lichen-covered 
sticks.—All were healthy and had eaten freely: 3 were 
on the hawthorn branch, 1 on the muslin, All were 
distinctly brown. 
J. Three of 7 wniformly brown larve, with black twigs.— 
One larva was dead, while 2 healthy ones had evidently 
eaten. Both were on the black twigs, and possessed the 
same dark brownish ground-colour with brown patches as 
the 4 last-mentioned larvee (1). 
K. The 4 most distinetly spotted or lightest larve, with 
brown stems.—One larva was dead, while 3 healthy ones 
had evidently eaten. All 3 were on the hawthorn-branch. 
This set still included the most distinctly white-spotted 
individuals of the whole 11. It was evident that no 
change occurred during hybernation. 
IV. THE 14 QUERCIFOLIA LARVA UPON GREEN LEAVES 
AND SHOOTS OF THE HAWTHORN. 
L. Seven larve enclosed in a muslin bag containing a 
branch of the hawthorn.—One larva was dead, 3 were on 
the branch, 2 on the muslin, while 1 became detached in 
removing the bag. All had left their foot-holds, with the 
doubtful exception of one on the branch. All 6 were 
healthy and irritable, and most of them had evidently fed ;
