LVIII. — Some undescribed Rhopalocera from Mesopotamia 

 and N.W. Persia ; and other Notes. By N. D. Riley. 



(Published by permission of the Trustees of the British Museum.) 



The following notes are based on the very rich material 

 brought from Mesopotamia and N.W. Persia by Lt.-Col. 

 H. D. Peile, I.M.S., F.E.S. Col. Peile is to be congratu- 

 lated highly on the excellent condition of the specimens, 

 tiie fullness of the data, and on the number of species 

 obtained, often under conditions not at all conducive to 

 entomological enthusiasm. The Museum also is greatly 

 indebted to him for the generosity with which he has pre- 

 sented not only the types of all the forms, but also " as 

 many as we want of everything else." 



Col. Peile hopes shortly to publish in the Journal of the 

 Bombay Nat. Hist. Soc. a fuller account of the Rhopalocera 

 of the regions in which he collected, and to figure the 

 majority of the new forms. Fuller particulars as to dates 

 and localities, &c., will be found therein. Only those speci- 

 meiis of the species mentioned below, which have been 

 incorporated in the General Collection of the Museum, are 

 referred to here.

Verity says of his type specimen : " La tache apicale, peu 

 etendue, mais tres noire et k limites tres nettes, rappelle 

 plutot celle de belemia, tandis que le trait discoidal tres 

 reduit, tres droit et aussi eloigne de la cote que chezfalloui,
