Key to the sub-families of Asiatic HesperhDjE. 



A. — Sub-family Hespeeiiisle. — When in a state of complete repose 

 the butterflies rest with their wings extended flat. The lower radial 

 (vein 5) of the forewing arises nearer to the upper radial (vein 6) than 

 to the third median branch (vein 4), the middle disco-cellular nervule 

 being consequently shorter than the lower one. The male insect nearly 

 invariably has a tuft of hair attached to the proximal end of the 

 hind tibiae, and occasionally has a costal fold on the forewing, but 

 is never furnished with androconia on the upperside of the forewing. 



B.— Sub-family Pamphildsle. — When in a state of complete repose 

 the butterflies rest with their wings perpendicularly closed over thein* 

 backs. The lower radial of the forewing arises* nearer to the third 

 median nervule than to the upper* radial, the middle disco-cellular 

 nervule being consequently longer than the lower one. The male 

 insect frequently has patches of androconia of varying form on the 

 upperside of the forewing, but never has either a costal fold on the 

 forewing or a tuft* of hair on the hind tibiae. 



There seems no doubt that the above two sub-families represent two 

 perfectly natural groups, as not only do they agree in neuration and 

 habits, but a peculiar fades runs through each group, by which alone, 

 with a little practice,, the great majority of species can be readily 

 assigned to their correct sub-family without the necessity of a minute 

 examination of their neuration or a knowledge of their habits, though, 

 of course, information on both these points should subsequently be 

 obtained to confirm the correct position of any species. 

 Sub-family Hesperiin^e. 



In my above-quoted revision of the genera of the ITesperiidce, it 

 was found convenient to divide the present sub-family into two sections 

 on a slight character of neuration, but, as nearly all the genera of the 

 first section are confined to the New World, it has been thought more 

 satisfactory to include all the Asiatic genera in one key. 



* In some species of the third section of this sub-family, the lower radial is as in the 

 Eesperiince, and there is a tuft on the hind tibiae of the male, but in other respects this section 

 is nearer to the Pamphilince, and its peculiar palpi serve to distinguish it from all the genera 

 of the Hcsperiinw,
