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. Pieridse. 1. Euchloe ausonia persica, Verity. Rhop.

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, #â–
