 than give an unsatisfactory description, though I still believe the 

 Bhim Tal specimen to be correctly identified. Should varia really

A. degenera, Walk. (Anthrax) also comes here, but requires 

 confirmation as Indian. It was introduced by me on three speci- 

 mens in my collection from Kandy, which were identified as 

 probably this species, but they have been sent to England and are 

 not available for comparison.
