 forming two pilose branches, terminated by oblique elliptical lobes. 

 Palpi short, biarticulate ?, clothed with short hairs, attached to the an- 

 terior angles of the mentuin ; first joint globose ; second subovate. 

 Antennae fourteen-jointed, setaceous, nioniliform, pubescent, slightly 

 setose ; first joint subcyliudrical, longer than the rest ; second globose, 

 rather stouter ; the rest oval, slightly tapering ; fourteenth a little 

 longer, attenuated. Thorax gibbons, ovate. Scutellum semiovate.

 springing from a common petiole, which proceeds from the subcostal at 

 a little beyond half the length of the wing ; cubital joined near its base 

 to the third externo-medial by a veinlet, whose angle emits the first 

 externo-medial ; the latter is joined to the third externo-medial by a 

 veinlet, whose middle emits the second externo-medial ; subanal joined
