A LIST OF INDIAN BUTTERFLIES. 55o 



keys to aid in the identification of species and results of the 

 study of the male organs, 

 (vi) Other important works are : — 



(rt) Rothschild and Jordan's '•' Revisions "" of the Oriental 

 Papilios and Charaxes (Nov. Zool., 1895 and 1896) based on 

 the male organs ; the principle of denoting a local race by 

 a second name is here introduced. 



(6) De Niceville's "New and little known Indo Malayan 

 butterflies "' appearing in this and the Asiatic Society's 

 Journal from 1 8 8 9 to 1 9 1 . 



(c) Bethune Baker's "Revision of the Amblypodia group," 

 1903, based on the male organs. 



(cV) Chapman's " Review of the genus Lycasnopsis " 

 (= Cyaniris), 1908, based on the male organs. 



(e) Verity's " Rhopalocera Palsearctica," a French work 

 with good figures and plenty of detail ; at present only the 

 Papilionidas and Pieridse have been completed. 

 In this list an attempt has been made to correlate the works of 

 Seitz, Bingham and Moore on the basis described below. 



The general arrangement given by Bingham has been followed, 

 Seitz differs in placing the Papilionidse and Pieridse first. Moore 

 and Seitz have further subdivided some of the sub-families into 

 groups, but as these groups are often more artificial than natural 

 and run into each other, there seems to be no advantage to be 

 gained by their employment. Theclinee is restricted to the Thecla- 

 Ilerda group and Deudoriginee introduced for the rest of 

 Bingham's " Theclinse '' : the Lyctenid sub-families are not very 

 satisfactor3^ Ismeninge is here used for the Ismene group is the 

 Hesperiid^. 



The most natural arrangement of genera is in the form of a 

 genealogical tree and consequently a linear method can never be 

 satisfactory. Bingham's order of genera has been followed with 

 the exception of the Satyrinas, where Seitz's arrangement has been 

 adopted ; the position of Cethosia and a few other genera have 

 been changed. Aphn83us has been placed next Chrysophanus, as 

 in Palteai'ctic territory these two genera are closely allied. The 

 Deudoryx and Camena groups have been brought together.
