cubital cell about basal 0.35, the second meets third cell at basal 

 0.2; the basal and transverse veins in forewings and the subdiscoidal 

 and cubitus in rear wings disjointed just about the length of the 

 transverse vein; the basal five joints of antennae cylindrical, the rest 

 increasingly to apex slightly concave beneath and convex above; 

 ratio of lengths of third and fourth joints is 10:10; clypeus with the 

 sides oblique, the apex 0.7 as wide as base, the width at base about 

 1.5 as long as length; rather wide, transparent rim across front edge 

 of clypeus; head 1.1 as broad as long; upper interocular distance 

 (13) equal to the lower; parameres of medium size for genus, the 

 volsellae with a series of long hairs on inner sides from deep pores; 

 subgenital plate with onlj^ a very short flat triangular surface at 

 base, from its apex a sharp ridge extends to apex. 



Length head and thorax 4.4 mm., abdomen 5.3 mm., forewing 

 6.7 mm., rear wing 4.6 mm.; length genitalia 0.86 mm., width 0.53 

 mm., length subgenital 0.86 mm., width 0.53 mm.

Holotype male. Body black with no color reflection, but various 

 parts colored as noted; mandibles (except slightly reddish apex), 

 clypeus, face, and broad inner orbits to just above antennae, white; 

 lower, front, outside corners, of posterior edge of pronotum and fore- 

 coxae, white; the other two pairs of coxae and rest of legs, except 

 tarsal joints, reddish yellow; last joint foretarsi, last three joints 

 midtarsi, and last four joints of last tarsi, dark; basal three segments 

 of abdomen yellow above and below except a dark streak across 

 dorsal surface of third; rest of abdomen black except the last tergite 

 which is white; mouth parts dark yellowish; first joint antennae 

 white beneath, reddish above, the next four or five joints slightly 

 yeUowish beneath, the dorsal surface of these and rest of joints black; 

 antennae with all joints cylindrical, densely covered with short 

 spines; head and thorax covered with a very delicate sUvery pubes- 

 cence, long white hairs under head and on propodeum; wings hyaline, 

 not yellowish, veins and stigma yellowish, shining, with gi"eenish 

 reflection in reflected light; fij'st recurrent vein meets second cubital 

 cell at basal 0.4, the second recurrent meets second cubital at basal 

 0.4; basal vein in forewings basad of transverse by a little more than 

 a third the length of latter; in rear wings subdiscoidal basad of cubital 

 vein by almost length of transverse; clypeus with a narrow transparent
