Section I. 

 Palpi various, but never as in Section III. Lower radial of fore- 

 wing straight throughout its length and not arising markedly nearer 

 to the third median branch than to the upper radial, the middle disco- 

 cellular being therefore only slightly longer than the lower one. 

 Key to the Asiatic, Genera. 



A. Fore tibiae without epiphysis, and hind tibise with terminal 



spurs only. 



a. *Hindwing, second median branch immediately before 



end of cell, first median branch nearer to end of cell 



than to base of wing. 



Pamphila, Fabricius. 



b. *Hindwing, second median branch well before end of 



cell, first median branch nearer to base of wing than 



to end of cell. 



Heteroptertts, Dumeril. 



B. Fore tibise with epiphysis, and hind tibia? with terminal 



and medial pairs of spurs. 

 a. First subcostal branch of forewing running very close to 9 



or actually touching, costal nervure. 

 a}. Terminal joint of palpi porrect, plainly visible. 



a 2 . First median branch of forewing nearer to end of cell 

 than to base of wing. 



Bar^cus, Moore. 

 IP. First median branch of forewing nearer to base of 

 wing than to end of cell. 



Astictopterus, Felder. 

 fAposTicTOPTERUS, Leech. 

 b 1 . Terminal joint of palpi concealed in clothing of second 

 joint. 



Sanctis, de Niceville. 

 c 1 . Terminal joint of palpi erect, usually long, slender, and 

 curving over vertex. 

 a 3 . Forewing, second median about twice as far from first 

 as from third ; hindwing, second median well before 

 end of cell. 



Korutsaialos, Watson. 



_ * In my P. Z. S. paper referred to above, the forewing is given instead of the hindwing 

 owing to an unfortunate oversight. 



f In describing this genus Mr. Leech does not say how it differs from Astictopterus with 

 which he says it agrees in neuration. The type species figured might from its appearance 

 belong either to Astictopterus or Sanctis.
