Head rather narrow, clothed with hair. 



Eyes oval, prominent. 



Maxillce more than equal in length to the thorax. 



Labial Palpi slightly divergent, ascending, rising considerably above the forehead, clothed with 

 appressed scales. First joint stout, short, curved ; second joint more than five times the length 

 of the first, much swollen beyond the middle, smaller towards the apes, which is obliquely 

 truncate, set in front with long erect seta? ; third joint slender, elongate, oval, about equal in 

 length to the first. 



Antennce about three fourths the length of the body, gradually clavate ; the club slender, rather 

 pointed, grooved below. 

 Thorax oval, not robust ; the prothorax small, but distinct. 



Anterior Wings triangular ; the anterior margin and apex slightly rounded ; outer margin 

 sinuate-dentate, not two thirds the length of the anterior ; inner margin slightly sinuate, 

 rather longer than the outer. Costal nervure stout, not extending much beyond the middle of 

 the wing. Subcostal nervure slender, placed very close to the costal, five-branched ; its first 

 nervule thrown off just before the end of the cell ; the first and second, and the third and fourth, 

 nervules about equally distant from one another ; the third rather nearer to the second than to 

 the fourth. Cell not quite half the length of the wing. Upper disco-cellular nervule ahnost 

 wanting. Middle disco-cellular nearly straight, directed slightly inwards. Lower disco-cellular 

 twice the length of the middle disco-cellular, directed first slightly inwards, then curving 

 outwards, uniting to the third median nervule almost immediately beyond its origin. Internal 

 nervure wanting. 



Posterior Wings subtriangular, all the margins of about equal length ; the anterior slightly, the 

 outer much, rounded, the latter more or less deeply dentate ; the inner margin forming a distinct 

 channel for the reception of the abdomen, emarginate beyond the termination of the internal 

 nervure.
