BOTYS HYALINALIS. 121 



Jeffrey supplied them with dry beech leaves, on which 

 they soon constructed their tough hibernacula, and 

 were afterwards placed out of doors with a potted 

 plant of Centaurea. About the middle of December, 

 during mild weather, it was noticed that they had 

 nibbled some of the leaves, but the larvae themselves 

 were not seen. In January, 1884, I received Mr. 

 Buckler's stock of hibernating larvae, some ten or 

 twelve in number, but did not examine them for some 

 time ; on the 8th of March I opened a little web, and 

 found the enclosed larva quite dormant. Soon after 

 this they must have begun to feed again, for on the 

 19th of March Mr. Jeffrev found a Centaurea leaf 

 nibbled asunder near some loose spinning of silk, and 

 on the 31st I found similar indications of my larvae 

 being at work. On the 7th of April, in the evening, I 

 examined my growing plant of Centaurea, and saw 

 that I had three larvae alive and feeding, apparently 

 still using their hibernacula for hiding-places, and 

 spinning short galleries from them to the tender young 

 leaves just shooting out of the earth, the whole 

 substance of which they ate in the usual way ; one of 

 these larvae was about to moult. On the 8th of May I 

 found them full-grown, and during the next fortnight 

 they spun gauzy cocoons, and became pupae during 

 the first week in Jane; unfortunately, I kept them too 

 dry, and bred only one moth, 27th of June. Mr. 

 Jeffrey's larvae were rather later in their dates, 

 becoming pupae towards the end of June ; and he bred 

 the moths from the 5th to the 13th July, and again 

 captured the moths flying at large on the 31st of 



The eggs are described as being deposited in little 

 patches, somewhat overlapping each other ; they are 

 flat in form, of a pale honey colour, and so transparent 

 that the development of the larvae within could be 

 plainly watched; thus in about a week the eyes could 

 be seen, and in two or three days more the organs of
