behveen lepidopteroiis larvfe and their surroimdings. 851 



3Iay 2oth. The last-named larva had died. Neither of 

 these larva? had grown larg-e. 



w 



The 2 largest larvse separated from M on April 16th, 

 Both were greyish-brown with distinct wliite patches. 



April 2.1st. Re-fed. Unchanged. The larvfe were also 

 re-fed on the 23rd, 27th, May 3rd, 11th, l(3th, and 22nd, 

 and examined on each occasion. The appearance remained 

 the same throughout. On the 25th both were sent to 

 Lord Walsingham. 



Second General Compaeisox after Hybernation. 



April Tlth, 1894. The larvae 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 LARV.E WITH BLACK TWIGS BEFORE 

 HYBERNATION. 



A. The three chequered larva} with black twigs. — These 

 larva? were unchano-ed and still remained the lightest of 

 the whole of series T. Hence the black twigs had pro- 

 duced no effect during hybernation. 



B. The Jive darJcest lo/rvm 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 larva? 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 sir dark larvie with black ticigs. — Only one 

 larva was alive, and this was dark with very faint dull 

 white spots. 



All the above described larvae were healthy and 

 well up to the average size. 



II. THE QUERCIFOLIA LARV.E WITH LICHEN-COVERED 

 STICKS BEFORE HYBERNATION. 



D. The four dark, white-marked lartie, icith lichen-covered 

 sticks. — Three larva? were alive and unchanged : one was 

 very small.
