between lepidopterous larve and their surroundings. 351 
May 25th. The last-named larva had died. Neither of 
these larvee had grown large. 
M! 
The 2 largest larvee separated from M on April 16th. 
Both were greyish-brown with distinct white patches. 
April 21st. Re-fed. Unchanged. The larve were also 
re-fed on the 23rd, 27th, May 8rd, 11th, 16th, and 22nd, 
and examined on each occasion. The appearance remained 
the same throughout. On the 25th both were sent to 
Lord Walsingham. 
SECOND GENERAL COMPARISON AFTER HyYBERNATION. 
April 27th, 1894. The larvee were carefully compared 
and were all placed upon a background of white paper. 
Nearly all of them were sluggish, probably preparatory to 
the last ecdysis. 
I. THE QUERCIFOLIA LARVA WITH BLACK TWIGS BEFORE 
HYBERNATION. 
A. The three chequered larve with black twigs——These 
larvee were unchanged and still remained the lightest of 
the whole of series I. Hence the black twigs had _pro- 
duced no effect during hybernation. 
B. Lhe five darkest larvx enclosed with lichen-covered sticks 
during hybernation.—One was very dark, the darkest of 
the whole group; 1 was dark with faint light spots; 3 
were black chequered with white markings, which however 
were less developed than in A. 
It is possible that these last-mentioned three larvae may 
indicate some susceptibility to the effect of the lichen- 
covered sticks after they were enclosed upon the tree and 
before the commencement of hybernation. 
C. The six dark larve with black twigs—Only one 
larva was alive, and this was dark with very faint dull 
white spots. 
All the above described 9 larva were healthy and 
well up to the average size. 
II. THE QUERCIFOLIA LARV& WITH LICHEN-COVERED 
STICKS BEFORE HYBERNATION. 
D. Lhe four dark, white-marked larve, with lichen-covered 
sticks,—Three larvae were alive and unchanged: one was 
very small.
