 The male is new. 



Male. — Integument with a very dark-green or bluish green 

 luster. Clypeus pale yellow except on the margin, and without 

 dark dots. Flagellum dark reddish ferruginous, blackish above. 

 Small joints of tarsi ferruginous. Tegulae dark testaceous brown. 

 Wings rather dusky hyaline, the stigma and nervures reddish 

 brown. Frons and vertex finely granular-striate. Face below an- 

 tennae dullish, finely shagreened and indistinctly punctured, the 

 clypeus a little more shining and minutely tessellate. Mesoscutum, 

 scutellum, and metanotum finely tessellate and dullish, the scutel- 

 lum a little more shining than the other parts. Basal area very 

 large, finely rugulose, smoother toward apex, the sculpture coarser 

 than that of remainder of propodeum. Abdomen minutely tessel- 

 late, a little dullish and impunctate. Antennae long, with the mid- 

 dle joints of flagellum distinctly longer than thick, and joint 3 

 shorter than 4. First abscissa of radius very short or puncti- 

 form. Pubescence whitish, moderately long and dense on cheeks 

 and pleura. Usually with much black hair present on sides of 

 face and behind summit of eyes. Genitalia short and compact. 

 Parameres of stipites very stout, the expanded apical part semi- 

 oval, about twice as long as wide, with the inner margin evenly 

 and convexly arcuate from base to apex of the expansion. Sagit- 

 tae dilated and bulbous at base, the apical part half compressed, 

 with very thick, blunt, spreading tips, the dorsal crest of each com- 

 ponent, just beyond the bulbous portion, much thickened and 

 protuberant. Length 5-7 mm.; anterior wing 4.3-4.8 mm. 



Female. — Like the male, but greenish luster perhaps a little 

 less evident and most distinct on the abdomen. Sculpture as in 

 male, with the clypeus dull, minutely granular-tessellate and ob- 

 scurely punctate. Process of labrum quadrate, about as long as 

 wide, truncate at apex, and a little widened toward the base. 

 Facial foveae narrow, reaching a little below level of antennae, 

 and usually a light fulvous brown. Pubescence whitish, tinged 

 with brownish ochreous on vertex and notum of thorax. Apical 

 fimbria brown. Tergites 2 to 4 each with a white apical fringe, 

 broadly interrupted on 2 and 3. Length about 7 mm.; anterior 

 wing 4.8-5.2 mm.
