and two of the club combined about equal to the combined funicle and 

 pedicel; forewing broad, evenly rounded at apex, the discal cilia sparse 

 and arranged in several distinct rows as follows; a row from the uncus of 

 stigmal vein to the anterior margin of wing near apex and corresponding 

 to the radial vein of some Hymenoptera, the area before this row with 

 only three or four irregularly placed cilia; a very distinct row from the 

 apex of stigmal vein to the apical middle of wing and between this row 

 and the one corresponding to radius lie about five shorter rows of less 

 regularly arranged cilia; behind this median row and extending to the 

 apex of the wing is a moderately broad nearly hairless streak bounded 

 caudad by another distinct row of cilia; the ciliation behind this row 

 sparse and consisting of about three or four more or less poorly defined 

 rows with some irregularly placed cilia between; transverse row of cilia 

 behind the stigmal vein composed of about six hairs; longest marginal 

 cilia of the forewing equal to approximately one-fourth to one-fifth the 

 greatest breadth of wing; discal ciliation of the hind wing very weak and 

 apparently consisting of a very obscure row along the anterior margin, 

 and a somewhat more distinct row medially, otherwise entirely bare; 

 marginal cilia on the posterior margin of the hind wing fully twice as long 

 as the width of wing, those on the front margin hardly half as long as the 

 wing breadth; front tibiae slightly swollen with three obscure tooth-like 

 projections on the anterior margin each bearing a short spine or hair; 

 abdomen longer than head and thorax, pointed at apex; ovipositor barely 

 exposed at apex. Color very pale lemon yellow, the eyes and ocelli reddish 

 when mounted in balsam; mandibles brownish; first joint of funicle and 

 the first and last joints of club blackish; pedicel also slightly fuscous above; 

 apex of ovipositor sheaths black; apical tarsal joints blackish; wings 

 hyaline, the venation pale. 



Male. Length .71 mm. Except for the slightly smaller size and the 

 fact that the abdomen is slightly shorter and not pointed at apex the male 

 agrees with the female.
