XXXVI. — On three new Species of Gonepteiyx from India, 

 Japan, and Syria. By ARTHUR G. BUTLER, F.L.S. &c. 



In a collection from the North-west Provinces recently pre- 

 sented to the Museum by J. F. Dtithie, Esq., I find an 

 interesting new species of the genus Gonepteryx. 



To those lepidopterists who regard the whole genus as 

 consisting of one extremely variable and widely distributed 

 species this unexpected novelty will doubtless be nothing 

 more than another example of what they inaccurately call local 

 varieties ; to me it is a local form, and therefore a true 

 species of the only kind existing in the Lepidoptera. I pro- 

 pose to call it G. carnipennis. 



G. carnipennis belongs to the rhamni group; and before 

 pointing out how it differs from its two nearest allies, G. 

 rhamni of Europe and G. nepalensis, I may mention that I 

 have before me specimens of the following species : — 



G. rhamni, G. nepalensis, G. cleopatra, G. maderensis, G. 

 cleohule, G. farinosa, G. aspxxsia, and G. zaneka, besides two 

 other species which are at present unnamed in our collection 

 and hitherto undescribed. 



Gonepteryx nepalensis was originally separated from G. 

 rhamni by Mr. G. R. Gray as a mere variety of the latter; 

 but subsequently, in the ' Genera of Diurnal Lepidoptera,' 

 p. 71, it was named by Edward Doubleday. Neither of these 

 gentlemen, however, mentioned any character by which it 

 could be distinguished from G. rhamni. The following 

 synopsis will readily separate the three species : — 



a. Wings above in male yellow, in female greenish white. 



1. Wings of both sexes with ill-de- 

 fined marginal brown points ; upper 

 surface of male of a deep sulphur-yellow 

 colour ; secondaries of female decidedly 

 greenish ; wings below with costal area 

 of primaries and whole of secondaries 

 decidedly greenish G. rhamni. Europe.
