Genus Listekia, no v. 



Male. Forbwing, ratlier long and narrow ; casta almost straight, 

 apex to termination of third median nervule truncate, outer margin 

 below truncation emai'ginate, inner angle rather acute, inner margin 

 lobed before the middle ; costal nervier e ending just beyond the upper end 

 of the discoidal cell ; subcostal nervure with three branches, excluding the 

 terminal portion of the nervure which is often counted as an additional 

 subcostal nervule, terminating on the costa just before the apex of the 

 wing; first subcostal nervide arising from the subcostal nervure a little 

 beyond the middle of the cell, ending on the costa beyond the end of 

 the cell ; second subcostal arising nearer to the apex of the cell than to 

 the origin of the first subcostal ; third subcostal ai'ising midway between 

 the end of the cell and the apex of the wing ; upper disco-cellular ner- 

 vule wanting; middle disco-cellular arising at the point where the 

 upper discoidal nervule is given off, concave ; loiver disco-cellular longer 

 than the middle disco-cellular, in the same straight line, concave; 

 second median nervule arising well before the lower end of the cell; 

 first median arising twice as far from the base of the second as the 

 second does from the end of the cell; submedian nervure straight; a 

 sexual tuft of hairs attached to the inner margin before its middle and 

 turned under and upwards. Hindaving, large, broad ; costa nearly 

 straight, outer margin broadly curved to the anal angle, slightly produced 

 at the termination of the third median nervule ; anal lobe very large ; 

 abdominal margin excavated anterior to the anal lobe; costal nervure 

 ending at the apex of the wing, very much curved at the base, then straight 

 to the apex ; first subcostal nervule ai-ising well before the apex of the 

 cell, ending at the apex of the wing ; iipper disco-cellular nervule straight, 

 loioer disco-cellular also straight, in the same straight line as the upper, 

 both slightly outwardly oblique, a little longer than the upper ; second 

 median nervule arising just before the lower end of the cell ; submedian 

 nervure straight ; internal nervure short, recurved ; a sexual glandular 

 " scale " patch extending from the base of the first subcostal nervule to 

 the termination of the discoidal cell, not extending into the cell, but 

 with as large or rather larger an area anterior to the first subcostal 

 nervule as there is posterior to that vein. Antennm about half as long 

 as the costa of the fore wing, with a large well-formed club. Palpi 

 rather long, porrect. Eyes hairy. Thorax rather robust. Abdomen 

 short, extending to two-thirds the length of the abdominal margin of 

 the hindwing only. Cilia of the hindwing very long and coarse. Type^

The secondary male sexual characters of the genus are nearest as 

 far as Indian genera go to those of Bindahara, Moore, the " scale "
