HERON A. 237 



Genus HERONA. 



Herona, Doubleday, in Dblday., Westiv. fy Hew. Gen. Di. Lep. 1850, 

 p. 293, pi. 41 ; tie N. Butt. hid. ii, 1886, p. 60 ; Moore, Lep. Ind. 

 iii, 1896-99, p. 22. 



Type, H. marathus, Doubleday, from Sikhim. 



Range. Sikhim to Tenasserim, extending to Sumatra and 

 Borneo. 



S 2 • Venation very similar to that of Apatura, but in the fore 

 wing vein 9 is emitted out of 7 well before the middle of the wing, 

 veins 10 and 11 closer to the base of 7, and consequently pro- 

 portionately shorter, as is also vein 12. The tornus of the hind 

 wing is more rounded, not produced, and the club of the antennae 

 is flattened, not rounded as in Apatura. For the rest Herona 

 closely resembles that genus in structure. 



Key to the forms of Herona. 



a . Upperside of wings with broad markings ; 



transverse bands on hind wing coalescing 



near terraen H. marathus, p. 237. 



b. Upperside of wings with comparatively 



narrow markings ; transverse bands on 

 hind wing not coalescing. 

 a. £ & 5 . Markings on both fore and hind
