A revision of the Genera of flic Suh-family l^ieriiiie : by 

 Arthur Gardiner Butler, F.L.S., F.Z.S., &c. 



It is now about twenty-three years since Mr. Donbleday 

 revised this group of Butterflies iu the " Genera of Diurnal 

 Lepidoptera," in this work he recognized eighteen distinct 

 genera, several of which he separated into sections in the 

 belief " that at some future time they would lie adopted as 

 generic divisions." 



Of the eighteen genera above mentioned only eleven 

 have any claim to stand, viz., Euterpe, Swains ; Fieris, 

 Boisd ; (but not of Schrank, Hiibner, nor Latreille) ; Zr<jris, 

 Eambur ; Nctthalis, Boisd; Hehomoict, Hiibner; Eronla, 

 Boisd. ; Callidnjas, Boisd. and Terias, Swainson, (for con- 

 venience sake) ; Goncptcryx, Leach ; Colias, Fabricius ; the 

 remainder were all previously characterized or the generic 

 name preoccupied. 



Since the publication of the " Genera " the group has 

 Ijeen taken in hand by IMessrs. Wallengren, Felder, 

 Herrich Schaffer, Eeakii-t, and Wallace, all of whom have 

 added genera, and thus greatly facilitated the study of the 

 sub-family. 



The unwieldy genus Fieris has been rendered more in- 

 telligiljle by the labours of Messrs. Felder, Wallengien, and 

 Wallace, but liitherto it has still remained far too large and 

 will readily l^ear further sub-division ; the genus Terias is 

 almost in a worse condition, the little genus Leueiclia of 

 Herricli-Sehaffer only having relieved it of two or three 

 species. 



In the following pages I hope to be enabled to ad- 

 vance the study of these beautiful Initterflies by a careful 

 revision of their characters and liy the erection of new 



EEVISION OF SYNONYMY.
