 collection of Mr. G. B. Jloutledge, is entirely white excepting- 

 two black dots at the apex of the discal cell. Hebridean

 and other low-growing plants, and upon grass ; feeding 

 principally at night. 



A most exti'aordiuary, abnormal specimen of this larva 



was reared from the egg by ilr. E. H. Jones, and exhibited
