 Body large or very large, rarely of middle size, elongated, cylindri- 

 cal, slightly pubescent. Head small, rounded, slightly attenuated be- 

 hind. Front flat. Eyes round, moderately remote. Proboscis rather 

 long, nearly cylindrical, acute at the tip above. Palpi four-jointed, de- 

 cumbent, nearly cylindrical ; first, second, and third joints nearly equal ; 

 fourth elongated, pubescent. Antenna thirteen-jointed, porrect, simple, 

 nearly filiform, of various length; first joint rather long, cylindrical; 

 second small, cyathiform ; the rest cylindrical or subcylindrical, verti- 

 cillate-pilose. Prothorax distinct. Thorax elliptical. Scutellum small. 

 Metathorax slightly convex. Wings lanceolate, divaricate, narrow at 

 the base, rounded at the tips ; mediastinal vein joining the subcostal at 

 somewhat beyond two-thirds of the length of the wing ; subcostal end- 

 ing at a little before five-sixths of the length ; radial and cubital spring- 

 ing from a common petiole, which is rather more or less than one-half 

 of their length, and which proceeds from the subcostal at about two- 

 thirds of the length of the wing ; radial connected with the subcostal 

 by an oblique veinlet before one-third of its length ; cubital curved, 

 forming very near its base an angle, and then connected by a veinlet 

 with the third externo-medial ; first externo-medial springing from the 

 fore part of this veinlet, sessile in some species, but generally forked at 

 half its length, and connected at some distance from its fork with the
