the length of the inner. Fore wing with the apex acute ; veins 3 

 and 5 from close to angle of cell ; 10 closely approximated to 8, 9. 

 Hind wing with the cell short ; the discocellulars erect ; veins 3, 

 4, 5 radiating from angle of cell ; 6, 7 from upper angle, 7 anas- 

 tomosing with 8. 



SECT. I. (Protonoceras). Male with a tuft of forwardly-directed hair 

 between the antennae; antennae with the basal joint dilated, 

 the shaft given off from its outer side, much bent near base, 

 then with some small serrations on inner side and with long 

 cilia. 



A. Antennce of male with a long curved tuft of hair from the inner 

 side of basal joint; the tuft between the antennae long.

Fuscous : palpi white below at base ; frons and basal joint of 



antennae white. Fore wing

 line ; a prominent dark-edged 

 white discocellular lunule ; a-

Differs from tropicalis in the fore wing having a dark spot in the 

 cell and dark discocellular lunule ; hind wing with no white spot 

 beyond the discocellular lunule. 



The typical male form from Ceylon and Borneo has the frontal 

 tuft rufous and more developed than in the Mlgiri form fusci- 

 lunalis, and on the fore wing has a white spot between the two- 

 cell-spots.
