224 BOMBYLIIDjE. 



Described from several specimens in the Indian Museum from 

 Medha, Yenha Valley, Satara District, 2200 ft., Bombay Presi- 

 dency, 17-23. iv. 1912 (Gravely type) ; Pallode, Travancore, 

 13. xi. 1908 (Annandale) ; Bangalore, iii. 1910 ; Chapra, Bengal 

 (Mackenzie). 



This species is very near A. (Anthrax) eor&o, Rond., but 

 Prof. Gestro has very kindly compared a specimen with Eondani's 

 type in the Genoa Museum and pronounced it quite distinct, in 

 spite of the similarity of characters contained in the description 

 of that species. It is with pleasure, therefore, that I name the 

 present species after Prof. Gestro. 



The legs are sometimes much paler, occasionally wholly pale 

 brown.
