Front wings with tlie marginal vein short, the postmarginal vein very short. 5 



Front wings with the marginal vein long, linear, longer than the stigmal 



vein, the stigmal and postmarginal veins not short, or very 



rarelj^ short, the postmarginal most frequently longer than 



the stigmal. 



Fnnicle 6-jointed without ring-joints 3 



Funicle 4-jointed with two ring-joints. 



Frons minutely shagreened, with minute punctures scattered over 

 the surface; scape slender, cylindrical, the iiagelluin at the 

 most subclavate; stigmal veiu very oblique, subclavate.

 front wings with a discoidal blotch. 

 Frons very minutely shagreened, with minute punctures scattered over 

 the surface, or almost smooth. 



Head viewed from in front longer than wide; scuteHum with a tuft 

 of long hairs ; abdomen scarcely longer than the head and 

 thorax united, the ovipositor 7iot or scarcely exserted; 

 flagellum gradually broadened toward apex, compressed,

 of the abdomen; flagellum subclavate, not compressed, the 

 fanicle joints longer than thick. 



(5) Tineophoctonns Ashmead, new genus. 



4. Frons minutely shagreened, with minute punctures scattered over the surface; 



scape not compressedly dilated beneath, cylindrical or sub- 

 cylindrical. 

 Antenufe , not longer than the body, usually somewhat shorter, the first 

 joint of the flagellum rarely more than twice as long as thick ; 

 stigmal veiu not curved; axillte just meet at inner basal 



angle (6) Eric\jdnns Walker.
