Head rather small, scaly, but little if at all hairy. 



Eyes oval or rounded, prominent. 



Maxilla longer than the thorax. 



Labial Palpi divergent, ascending, rising considerably above the forehead. Basal joint short, 

 hairy ; second joint elongate, mostly much swollen, hairy, the hairs often very thinly scattered ; 

 third joint very short, especially in those species which have the second joint most swollen. 



Antenna? scarcely more than half the whole length of the body, rather abruptly clavate ; the club 

 compact, obtuse at the apex, the joints composing it not more distinct than those of the other 

 portion of the antenna?. 

 Thorax oval, generally rather elongate ; the prothorax very distinct. 



Anterior Wings opaque, or partially or wholly diaphanous, subtriangular, elongate ; the apex more 

 or less rounded ; the anterior margin but little arched ; outer margin seldom much more than 

 half the length of the anterior, sometimes nearly straight, except towards the apex, sometimes 

 rounded ; inner margin nearly straight. Costal nervure extending considerably beyond the 

 middle of the anterior margin. Subcostal nervure invariably five-branched ; its first nervule 

 thrown off at or near to the end of the cell, the second always considerably beyond the cell. 

 Cell seldom more than half the length of the wing. Upper disco-cellular very short, or 

 entirely wanting. Internal nervure wanting. 

 Posterior Wings obovate ; the anterior margin nearly straight ; the outer margin much rounded ; 

 the inner about equal in length to the outer, slightly embracing the base of the abdomen. Cell 

 always closed, narrow, sometimes very short, rarely half the length of the wing. Discoidal 

 nervure sometimes appearing to be a third subcostal nervule; sometimes united to the subcostal 

 nervure, or to its second nervule, by a distinct upper disco-cellular. Lower disco-cellular always 

 united to the third median nervule, often very close to its origin. 

 Anterior Legs of the males with the femur mostly longer than the tibia;. Tibia? nearly cylindric ; 

 smooth, or very slightly spiny ; longer than the tarsus. Tarsus cylindrical, or slightly fusiform ; 

 sometimes one-jointed, sometimes showing indications of four or five joints. Anterior Legs of
