Body large, long, slender, cylindrical, nearly smooth. Head small, 

 rounded, slightly attenuated behind; front rather prominent. Eyes 

 remote. Proboscis thick, cylindrical, acute at the tip above. Palpi 

 four-jointed ; first, second, and third joints nearly equal ; fourth longer 

 and more slender. Antennae thirteen-jointed, porrect, simple, pilose, 

 nearly filiform, setaceous towards the tips ; first joint somewhat obco- 

 nical ; second cyathiform, very short ; the rest cylindrical, more slender 

 towards the tips. Prothorax distinct. Scutellum small. Metathorax 

 slightly convex. Wings lanceolate, divaricate, narrow at the base, 

 rounded at the tips; subcostal vein approaching the costa at the 

 stigma, then receding from it, and joining it at four-fifths of the length, 

 connected with the radial by a short veinlet adjoining the stigma ; ra- 

 dial and cubital springing from a common petiole, which is about one- 

 fourth of their length, and proceeds from the subcostal at two-thirds of 

 the length ; cubital forked very near its base ; its hind fork forming an 

 angle near the base, and there connected by a transverse veinlet with 

 the third externo-medial ; the middle of this veinlet emits the second 

 externo-medial, and the latter is connected with the cubital by another 

 veinlet, which forms an angle in front, and then emits the first externo- 

 medial ; third externo-medial angular at its junction with the veinlet, 

 which is continued across it to the subanal ; anal and axillary complete ; 

 discal areolct pentagonal. Abdomen long, cylindrical, with eight seg- 

 ments. Legs long, slender, unarmed, nearly bare ; coxae short ; tibiae 

 with two short spurs ; ungues small. Male. Antennae hardly shorter
