legs lost) ; the forecoxae black, the last two pairs black (greenish tinted) 

 on about basal thbd, the rest yellowish; antennae dark brown dorsally, 

 yellowish ventrally; long hair on front edge of clypeus, mandibles 

 under head and on dorsal surface of propodeum; pencil of hairs on 

 mentum exceptionally noticeable, long and rather thick, reddish; 

 clypeus convex in front; with a faiily wide hairless rim in front, 2.0 

 times as wide as long; head a little over 1.1 as broad as long; interocular 

 distance 0.53 times the transfacial; the eyes converging below, the 

 upper interocular distance (100) 1.25 times the lower; the ratio of 

 lengths of fii'st four antennal joints is 40 : 15 : 70 : 55, thus the second and 

 third antennal joints (85) not equal to the vertex width (100); the 

 lateral ocelli a little more than 2.0 times as far from eyes as each 

 other; pronotum very short, transverse across posterior edge; front 

 and mesonotum very finely punctured; the propodeum finely striated; 

 wings hyaline, slightly yellowish, the veins and stigma bright yellow. 



Length head and thorax 4.7 mm., abdomen 5.3 mm., fore wing 

 9.2 mm., rear wing 6.6 mm.

Holotype Female. Ground color black; clypeus and face black, 

 front and vertex with a dull-green tinge; pronotum and propodeum a 

 greenish tint, the rest of thorax almost black; abdomen shining black 

 with just a hint of bluish iridescence, hardly noticeable; coxae and 

 trochanters black; all femora and all tibiae yellowish; all tarsi and 

 spurs black; hairy and woolly in appearance; numerous upright haks 

 on front of clypeus, mouth parts under head, on front, on coxae, 

 sides of thorax, propodeum (strongly on posterior half), and on 

 sternum of abdomen; densely silvery, pubescent (with a yellowish 

 tinge) on clypeus and face, and outer posterior corners of propodeum; 

 thorax with the pubescence less dense; abdomen with a silvery bloom, 

 in reflected light showing up as a patch on each side of third and 

 fom-th tergite; front, vertex and mesonotum finely, densely punctured; 

 scutellum and postcutellum with much larger more widely separated 

 punctures ; pygidium smooth and shining ; base of mandibles black, apical 

 half reddish; cl3T)eus rounded in front with a hakless shining rim 

 across front, reddish on rim; clypeus 2.0 as wide as long; head not 

 quite 1.2 as wide as long; interocular distance (70) slightly greater 

 than the lower (65); the joints of antennae becoming increasingly 

 thicker from thu'd to seventh; the lateral ocelli 2.0 as far from each 

 other as from eyes; ratio of length of first four antennal joints is 

 30:15:50:40, thus second and third joints not quite as long as vertex
