Holotype male. Clypeus, face, posterior orbits, and coxae black; 

 front, vertex, and mesonotum dull greenish; sides of thorax and 

 propodeum almost black but in certain reflected light appears a dull 

 bluish green in places, much less than on mesonotum; mandibles 

 almost all black, slightly reddish at apex; mouth parts brown; abdo- 

 men dark, slightly brownish especially on sides of fu'st tergite; all 

 trochanters, femora, and at least first two pairs tibiae, reddish (last 

 pair tibiae lost); foretarsi reddish except last three joints are dark 

 (last two pairs lost) ; first three joints antennae yellow beneath, brown 

 above (rest joints lost); inner orbits narrowly white to just above 

 antennae; clypeus thickened on front edge, strongly concave each 

 side of middle in front; clypeus 2.25 as broad as long; head about 1.25 

 as broad as long; interocular distance 0.59 of the transfacial; lower 

 interocular distance 0.9 the upper interocular (18); length third 

 antennal joint 14 on same scale as measurement of upper interocular 

 distance; lateral ocelli 2.0 as far from eyes as each other; face and 

 clypeus silvery pubescent; thorax not nearly as silvery pubescent as 

 face, but has rather long upright hair (as has the head) which gives 

 it a rather shaggy appearance; wings hyaline, veins and stigma black; 

 basal vein in forewings basad of transverse by 0.5 the length of latter; 

 genitalia and subgenital plate very much like that of clypeatus, and of 

 about same size, but the size of insect is larger and the various 

 measurements are different. 



Length of head and thorax 4.6 mm., abdomen ?, fore whig 8.3 mm., 

 rear wing 5.9 mm.
