for, after all, the number of possible combinations of the veins is limited. Some of 

 these fortuitous groups of species have up to now being treated as true genera, e.g. 

 Teriomina, (sensn Aurivillius) Citrinophila and Eresina, but their male genitalia have 

 retained, at least in part, their ancestral characters and their study reveals both the 

 different origins of the species comprising the group, and the artificiality of these so- 

 called genera. One may hope that when all the species of the Liptenini have been 

 methodically examined, it may be possible to trace their phylogenetic relationships, 

 and to group them in a natural classification. For the present however, I prefer to 

 admit defeat rather than yield to a love of symmetry by forming arbitrary groups, 

 whose systematic value would be no improvement on the present classification. 

 Hence I propose to retain provisionally the division of the subfamily into two sections 

 as done by Aurivillius, based on the relative positions of the origins of veins 6 and 7 

 of the fore wing, i.e. stalked or very close together, in the first group, far apart in the 

 second group. 



Section 1. 



Fore wing veins 6 and 7 stalked or very close together at point of origin. 

 Ditrbania Trimen. Fore wing 12 veins, vein 6 and the stem of veins 7+8+9 have 

 separate origins ; 11 arising nearer to 10 than to the base ; hind wing short 

 precostal vein present ; 7 not stalked on 6 ; costa strongly convex at its base ; 



3 and 4 far apart. 



Durbaniella van Son. Fore wing with vein n arising equidistant between 10 and 

 base ; hind wing with short precostal vein, cell about half as long as wing. 



Durbaniopsis van Son. Fore wing with vein 11 arising much nearer to vein 10 than 

 to base ; hind wing with short precostal vein, cell much shorter than in Dur- 

 baniella, about one-third as long as wing. 



Pseuderesia Butler. Fore wing (P. eleaza) with 12 veins, vein 6 stalked on 7+8+9, 

 10 from the upper angle of cell in <$, stalked on 7+8+9 in $ ; or (P. isca group) 

 10 from upper angle of cell ; hind wing with 7 stalked on 6, 5 nearer to 6 than 

 to 4, 3 and 4 far apart at origin. 



Citrinophila Kirby. Fore wing with 12 veins ; 6 and 7+8+9 have a common 

 stem ; 5 nearer to 6 than to 4 ; hind wing, 7 branched on 6, 5 nearer to 6 than 



4 ; 3 and 4 far apart. 



Teriomima Kirby, Baliochila Stempffer & Bennett, Cnodontes Stempffer & Bennett, 

 Euthecta Bennett. Fore wing with 12 veins ; 6 and 7+8+9 have a common 

 stem ; 5 nearer to 6 than to 4 ; hind wing, 7 free ; 5 nearer to 6 than to 4 ; 

 3 and 4 rather close together. 



Larinopoda Butler. Fore wing with 12 veins ; 6 separated from 7+8+9 ; cell 

 produced at the lower angle ; hind wing, 7 free ; cell short produced at the 

 lower angle ; 3 and 4 far apart ; 5 nearer to 6 than to 4. 



Liptena Hewitson, Falcuna Stempffer & Bennett. Fore wing with 12 veins ; 6 

 separated from 7+8+9 ; cell rather short, 5 nearer to 6 than to 4 ; hind wing, 

 7 free ; 3 and 4 slightly separated, connate, or slightly stalked.
