S. Antenna imperceptibly incrassate distally ; hook long. Crest of thorax 

 very high. Co.stal margin of forewing convex before middle owing to the strong 

 development of the scent-organ ; apex sinuate ; posterior area of wing mummy- 

 brown, tliis colour sharply defined at the fold, by which it is limited, a deep brown 

 triangular discal patch between 11' and M\ and an apical patch of the same colour; 

 hindwing mummy-brown, paler at distal margin, especially near apex. Under- 

 side : scent-organ of forewing very broad, strongly convex costally, distally limited 

 by the cross-veins, which are distorted : D" twice the length of U^, running distad, 

 D- and D^ forming a right angle which is open proximally, D^ forming an obtuse 

 angle with T)\ R" from angle D-. D', curved backwards near its base ; D^ of hind- 

 wing more than half the length of D^ 



Tenth tergite of the same type as in Inqiihris, but the apical process mucli 

 shorter (PL XLIV. f. 12), the ventral processes stouter and not so close together. 

 Clasper (PI. XLVII. f. 18) ending in a long, strongly chitiuised, slender process ; 

 dorsal margin strongly convex distally ; hair-scales of apex longer than clasper. 

 Penis-sheath with an indication of the triangular process found in cavij'er. 



?. Upperside of body and wings ochraceous-clay colour ; forewing flushed witli 

 fawn-colour. Chestnut mummy-brown area of forewing jiosteriorly truiuiate in front 

 of M-, continued as a tliin line to liindcr margin ; apex of forewing sinuate.

 much narrower scent-organ, and different neuration : D^ and D' of forewing in
