Body rather small, elongated, narrow, almost smooth, cinereous, oc- 

 casionally yellowish. Head small. Eyes contiguous above, subconnate 

 beneath. Proboscis short. Palpi four-jointed, decumbent ; first joint 

 very short, the rest nearly equal. Antennae sixteen-jointed, filiform, 

 slightly pilose, a little shorter than the thorax ; first joint cylindrical ; 

 second cyathiform ; third and following joints globose. Prothorax short. 

 Thorax convex. Wings incumbent, rather narrow ; mediastinal vein 

 ending at a little before two-thirds of the length of the wing, joined 

 by a veinlet to the subcostal at half the length ; subcostal ending at a 

 little before five-sixths of the length ; radial and cubital springing from 

 a common petiole, which nearly equals them in length, and springs 

 from the subcostal somewhat beyond one-third of the length ; radial 

 forked at one-fifth of its length ; its fore fork united near its base by a 

 veinlet to the subcostal ; cubital joined very near its base to the third 

 externo-medial by a veinlet which at two-thirds of its length hiridward 

 emits the first externo-medial ; the latter is united to the third externo- 

 medial by a veinlet whose angle emits the second externo-medial ; third 

 externo-medial united to the subanal by a veinlet opposite the base of 

 the second externo-medial ; anal vein and axillary vein complete, the 

 latter undulatory ; discal areolet pentagonal. Abdomen elongated, li-
