Length of body 1.9 mm.; length of forewing 2.5; width of head 

 0.75. General color dark brown or black; head and pro thorax jet 

 black; abdomen lighter; genitalia yellowish brown. 



Head not deflexed, almost as broad as thorax, finely punctate;

 posterior ocelli but less so than in preceding genus; with a con- 

 spicuous epiphysis near eye, over insertion of antennae. Eyes rather 

 large; posterior ocelli reniform in shape, situated well forward; 

 anterior ocellus in front at apex of excision, visible from above. 

 Antennae about three times as long as width of head, very stout and 

 thick; two basal segments very large; third about as long as first 

 two together. 



Thorax rather flattened; pronotum long, flat on dorsal surface; 

 pleurites very large and long; pleural suture oblique, almost as long 

 as episternum. Spur at base of hind tibiae not very large, but con- 

 spicuous. Wings large, hyaline, shining, less than two and a half 

 times as long as broad, quite broadly rounded at apex; first marginal 

 cell much smaller than second; second very large; venation very 

 distinctive (see figure) ; with a black band along Mg and Rs ; a black 

 band, also, along Cu^ and a third on H^. 



Genitalia. — Male. — Genital segment relatively rather small; forceps 

 short and slender; anal valve small, simple.
