Egg-laying of Erebia Glacialis. — Mr. J. A. Simes read 

 the following note: — "On the 15th July, 1912, I came across 

 Erebia ijlacialis in some numbers on a scree slope below the 

 summit of the Colette de Gily, Dauphiny, and sat down for a 

 while to watch them. Shortly afterwards I saw a 5 alight 

 on a piece of loose rock on the slope, sun itself for a time and 

 then proceed to walk slowly backwards until it reached the 

 lower end of the rock. It then bent its abdomen underneath 

 the slab of rock and deposited an eg^ on the lower surface of 

 it. The slab measured roughly 9 inches by 4 inches and the 

 broken part at the lower end was only about half an inch 

 thick, although the bulk of the slab was considerably thicker. 

 The only vegetation in the neighbourhood was a very fine- 

 leaved grass, tufts of Avhich grew here and there on the 

 screes. The nearest plant was about a foot and a half distant 

 from the slab on which the egg was deposited. I subsequently 

 observed a second female behave in precisely the same manner, 

 and eventually deposit an egg, on the underside of a detached 

 slab of rock on the scree slope." 



Mr. H. Howland-Brown observed that if the larva were 

 not hatched till the spring the egg might be placed in this 

 way for protection, but as the larva had been known to hatch 

 quickly and hibernate in that state this could not be the 

 cause. 



Mr. Douglas Pearson suggested that possibly the fact that 

 they had to hatch quickly was the reason for their position, as 

 the heat obtained from the sun beating on the slab might 

 hasten them. 



Dr. Chapman was of opinion that this was quite possible, 

 hut thought it also possible that the species, unlike most of 

 the genus, might hibernate as an egg, since they had only 

 been known to hibernate as larvae in captivity, and so under 

 unnatural conditions.
