Anterior wings Kubtri lingular, the costal margin strongly inched, the apex not acute and very slightly 

 rounded. First subcostal nervule emitted before cud i»f cell at three-fourths of its length, remaining 

 subcostal nervules emitted close together on apical fourth of wing. Upper disco-cellular nervule shortly, 

 obliquely, and outwardly directed at base, and suberect along its greater length ; lower disco-cellular 

 suberect and slightly concave at base and tin u din •<. -bd obli.jiiely outwards for its greatest length. Discoidal 

 nervules well separated at their origin. First median nervule with its base directed obliquely upwards in a 

 line with the median uervure, and then abruptly denexed to outer margin. Posterior wings subtriangular ; 

 costal margin arched ; outer margin rounded and scalloped ; anal angle produced into a broad, spatulate, 

 tail-like prolongation between the apices of the third median nervule and the submedian uervure. Discoidal 

 cell partly closed by an atrophied and curved disco-cellular nervule. In male specimen* these wings possess 

 two tufts of hair, probably concealing scent- secretory glauds or pouches, the first in the neighbourhood of 

 the submedian nervure, and the second and smaller tuft between that nervure and the third median nervule. 

 The terminal joints of the abdomen are also furnished with tufts of hair. 



This genus is of moderate extent, including some eight or nine species. It has a somewhat 

 restricted area, which extends from Continental India to a little beyond the Indo -Malayan 

 region. At present but one species is known as inhabiting the Malay Peninsula.

Male. Wings above dark fuliginous-brown. Anterior win^s with the costal .and outer margins 

 Koitu:wh;it paler, ami with fl distinctly paler submarginal fascia. Posterior wings with the outer margin 

 paler and with a distinctly paler submarginal fascia, the marginal fringe ochraceous and the anal-angular 

 caudate prolongation somewhat paler, with two sublimate bbirk spots, outwardly mur^hied with white; 

 these Bpots are placed near the apices of the third median nervule and submedian nervure. Wings 

 beneath greyish, crossed by numerous fuscous fascia? of varying width and hue ; the first commences 

 near costal base of anterior wings, aud is continued on posterior wings, narrowing and becoming somewhat 

 evanescent a little beyond the middle of submedian nervure; the second crosses the cells of both wings 

 about their centres, and terminates on inner side of third median nervule at about half its length ; the third 

 is short, crossing cell, but not passing median nervule of anterior wings; the fourth is pule, with its margins 

 darker, waved, and denexed beneath the third fascia on anterior wing, passing a little beyond the second 

 on posterior wing, and becoming confluent and terminating with that fascia beneath the median uervure ; 

 the fifth is wide and darkest, crossing both wings at cellular apices, and terminating a little beneath second 

 median nervule ; the sixth is widest, somewhat paler, with darker margins, outwardly sinuate and placed a 

 little beyond the fifth ; this sixth fascia is followed by three narrow fascism, which terminate on the abdominal
