Female type: Front wing 4.7 mm. long; combined face and clypeus 

 1.03 as high as wide, rather weakly, uniformly convex; facial punctures 

 strong and rather coarse, their interspaces about 0.5 their diameter; 

 point of interantennal process with an angle of 90 degrees; median swol- 

 len area of frons weakly defined; clypeus very wide, the median 0.75 of 

 its apical margin straight in front view and the lateral 0.125 weakly 

 upturned ; mandible broad, its lower margin a little convex to make the 

 taper more abrupt apically, its lower tooth very short, its outer face 

 densely punctate; hind ocellus separated from eye by 1.0 its long 

 diameter; cos tula complete but weak; second lateral area of propodeum 

 with a few hairs basally and apicolaterally ; hind femur 2.05 as long as 

 deep; front spur of hind tibia 2.9 as long as wide; punctures of second 

 tergite of moderate size, sharp, evenly distributed, their interspaces 

 about equal to their diameter. 



Black. Mandible and palpi brown; a small faint pale spot at top of 

 eye; tegula pale yellow, its apical half fulvous; legs uniformly fulvous.

Front wing 3.2 to 6.2 mm. long; combined face and clypeus about 

 1.0 as high as wide in male, about 1.20 as high as wide in female, 

 moderately convex in the vertical direction, strongly convex trans- 

 versely; facial punctures coarse and strong, their interspaces about 0.5 

 their diameter; point of interantennal process with about a 60-degree 

 angle; median swollen area of frons rather weakly defined; median 0.6 of 

 apical margin of clypeus truncate; lower margin of mandible convex 

 to make the taper of the mandible a little abrupt apically, the apex of 

 mandible moderately narrow, its lower tooth short; outer face of 

 mandible with sparse, rather coarse punctures; hind ocellus separated 

 from eye by about 1.1 its long diameter in male, by about 1.2 its long- 

 diameter in female; costula strong, usually complete; second lateral 

 area of propodeum with hairs laterally and apicolaterally ; hind femur 

 about 2.45 as long as deep in male, about 2.35 as long as deep in female; 

 front spur of hind tibia about 3.1 as long as wide in male, about 3.4 as
