172 EREBIA CASSIOPE. 



spots ; in about a fortnight the larva is fully formed, 

 and can be plainly seen through the transparent shell, 

 and it then soon eats its way out at the top of the 

 egg, and makes its first meal of the empty shell. The 

 young larva is dumpy in figure, stoutest in front, with 

 round head ; in colour it is very pale grey, the front 

 segments with a purplish tinge from the internal 

 organs showing through ; a rich yellow dorsal line, 

 two yellow lines on the side, and another just above 

 the spiracles ; the head brown, granulated all over ; the 

 usual dots jet black, furnished with very short 

 bristles ; spiracles black. In about ten days it seems 

 to have moulted, and has become green all over, with 

 darker green dorsal line, subdorsal line paler than the 

 ground colour, and the spiracular line yellowish, the 

 head brown. When the larva is about 9 mm. long its 

 figure is stout, with the back swelling in a curve which 

 is highest about segment 7 ; the head globular, 

 rather narrower than the second segment ; the tail set 

 with two short spines; the colour all over grass green, 

 the dorsal line darker green finely edged with 

 yellowish; subdorsal line yellow edged with dark 

 green, followed by a finer yellow line, then the green 

 spiracular line, and a broad well-defined whitish-yellow 

 subspiracular stripe ; the spiracles brown. This colora- 

 tion continued nearly unaltered as long as any of my 

 larvas lived, except that in the spring the yellowish 

 lines grew more whitish, and the head was green.

I have reared this species more than once, but can 

 find no more record of its changes than the following 

 notes made in 1874.
