Antennae much longer tlian the body, becoming very narrow towards the 

 apex; the first joint large, twice as long as the 2nd, the 3rd about as broad as the 

 anterior tibiae, with one row of oblong sensoria at the basal two thirds of it, the 

 4th much slenderer and shorter than the 3rd, distinctly longer than the 5th, the 

 latter being- still more slenderer, the 6th subequal to the 5th, anterhinarial much 

 longer than the postrhinarial. Rostrum reaches nearly to the middle coxae. 

 Head short, nearly the length of the pronotum. Primaries shorter than the anten- 

 nae, stigma long-lanceolate, stigmatic vein strongly curved, first oblique robust, 

 suberect, 2nd and 3rd obliques nearly parallel, the 2nd at the base somewhat nearer 

 to the 3rd than the first; furcals long, 2nd furcal branching at about 1/3 part 

 of the first near the base. Secondaries rather small, with 2 obliques, the both 

 being obsolete at the bases. Abdomen oval ; cornicles long, nearly 3 times as 

 broad, in the middle distinctly constricted, at the mouth somewhat trumpet- 

 shaped ; Cauda long, nearly twice as long as broad, near the base being constrict- 

 ed, genital lobe large and roundish. Legs long, with long hairs, all the femora 

 somewhat thickened ; empodial hairs oval, nearly as long as the claws. This
