Front wing of male 5.0 to 7.3 mm. long, of female 6.6 to 7.0 mm. 

 long; body slender; clypeiis narrow, in profile somewhat pyi'amidal; 

 tyloids on about 5 segments, rather blmit, extending about 0.6 the 

 length of the segments, and set slightly oblique to the long axes of 

 the segments; mesoscutum mat, with fine, very dense, subadjacent 

 punctures; scutellum with lateral carinae on its basal 0.3 ± in male, 

 on its basal 0.4 ± in female, the punctures on its disc dense, separated 

 by about 0.3 their diameter in male, almost touching in female; 

 metapleurum with intermingled and mutually obscuring dense, fine 

 punctures and wrinkles, those of male weaker than in female; pro- 

 podeum with rather sharp, irregularly reticulate wrinlding except 

 basad of its basal carina, its apical carina absent on its median 0.35 ±, 

 sublaterally strong and sharp; postpetiole mat, with scattered sparse, 

 fine, weak punctm'es ; portion of female postpetiole behind the spiracle 

 about 0.90 as long as wide; second tergite mat, with small, rather 

 weak punctures that are separated by about 0.8 their diameter near 

 center of tergite, denser on basal portion of tergite and sparser on 

 apical portion. 



Male: Head white, the central part of frons, vertex, and occiput 

 black; palpi white, brownish apically; scape and flagellum white, 

 fuscous dorsally; flagellum black, with a white band; propleurum, 

 pronotum except for a transverse band across neck region and a narrow 

 stripe on hind edge, tegula, mesosternum, prepectus except anteriorly 

 below, mesopleurum except near subtegular ridge, metapleurum except 

 some of its margins and a small brown subapical spot, spot in middle 

 of mesoscutum, often irregular anterolateral stripe on lateral lobe 

 of mesoscutum, ridges leading from base of scutellum, scutellum, 

 postscutellum, upper division of metapleurum except for its margins, 

 a semicircular spot on each side of propodeum basad of basal carina, 

 and propodeum apicad of its apical carina, white, the apical white on 

 propodeum extending forward medially; mesoscutum black or reddish 

 brown, except where described as white; area around scutella black; 

 front and middle coxae and trochanters white, the middle coxa with a 

 brown dorsal spot near its apex; front and middle legs beyond tro- 

 chanters fulvous, their tarsi brown apically; hind coxa fulvous, dor- 

 sally with a small basal fuscous area, a median indefinite dorsal fuscous 

 stripe, and a subbasal dorsal white spot; hind trochanters, femur, and 

 tibia fulvous, the apical 0.4 ± of tibia infuscate; hind tarsus white, 

 the basal 0.3 ± of its first segment and apex of its last segment fuscous; 

 abdomen fulvous, the first segment often partly infuscate and usually 

 with its apex pale yellow, the second tergite often somewhat infuscate 

 subbasally and sometimes with a subapical yellowish band.
