1. 



Often a sector leaving the posterior border 

 of loop which splits up the basal area into 

 an inner Held of small, closely arranged 

 cells and an outer of larger, irregularly 

 arranged colls. 

 Lobe of prothorax small. 

 Final antenodal nervure incomplete (except 



Aothriamanta and Macnxli/ila.r). 

 Wings usually long and broad. 

 Costal side of trigone in fore-wing short, shorter 

 than half the proximal. 



Stigma in fore-wing much longer than that of 

 hind-wing, 

 a'. Transverse ridges to 2nd, 3rd 4th and oth 

 abdominal segments. 

 Basal marking of hind-wing a clear, hyaline 

 amber tint . . 

 b\ Transverse ridges to L'nd, 3rd, and 4th ab- 

 dominal segments only, none to the oth. 

 Basal marking of hind-wing a dark, opaque 

 brown. (In T. basilaris this mark lies 

 in a clear amber setting) . . 

 Stigma in fore-wing only a little larger than in 

 hiud-wing 

 Stigma in fore and hind-wings the same size. 

 Loop open at the apex. . . 

 Costal side of trigone in the fore-wing long, 

 longer than half the proximal. 

 Antenodal nervures in fore-wing more than 7. 



PantaUi. 



Tiamea, 



HydrobasiletiK, 



Tholymis, 



i'. Trigone in hind-wing entire. 



Cubital nervures in hind-wing not more 

 than 1. 

 No supplementary nervures to bridge. 

 No secondary reticulation in basal area of 

 hind-wing, 

 a'. Eyes as broadly contiguous as the antero- 

 posterior diameter of occipital triangle. 

 Sectors of arc separated in the fore- 

 wing, shortly fused m hind-wing. 

 Wings marked with black and yellow, 



fuliginous, often with a metallic gloss. Rhijothemi><. 

 b'. Eyes as broadly contiguous as twice the 

 antero-posterior diameter of occipital 

 triangle. 

 Sectors of arc not separated in the 



fore-wing, long fusion in hind-wing. 

 Apex of loop not closed. 

 Wings not marked with black and yello-v 



and with no metallic gloss . . Zy.vomma. 



ii'. Trigone in hind-wing traversed several times. 

 Cubital nervures in hind-wings more than I. 

 Nearly always supplementary nervures to 



the bridge. 

 A secondary reticulation of small, closely- 

 Bet cells in basal area of hind-wing . . Camacinia. 

 ii . Antenodal nervures in fore-wing not mpre than 7,
