FeTnale. — ^Length 2.8 to 3 mm., fairly stout, colors yellow through 

 reddish yellow to black; head color variable; occiput, vertex, and 

 face at least down to antennal fossae always continuously black, 

 sometimes as far as oral area, all or only upper portion of malar 

 space black, and occasionally also hind portion of cheeks from malar 

 space to occiput, temples more or less brown yellow, circumocular 

 band and sometimes also an oblique stripe from it to scrobe, yellow, 

 ocular band often broadening on face, edges of antennal scrobe 

 usually narrowly yellow; scape dull yellow, basal two-thirds of 

 pedicel brown, apex lighter, flagellum chestnut-brown; neck and 

 front portion of mesal third to all of mesal half of pronotum, 

 black; mesonotum at times entirely black, at least prescutum and 

 scutel black, their lateral margins sometimes brown-yellow, scapulae 

 and axillae variously brownish or reddish yellow, in extreme cases 

 almost entirely so but at least hind part of axillae black, mesopleura 

 black, with upper edge adjoining tegulae sometimes yellowish, meta- 

 thorax and propodeum black; legs yellow, coxae sometimes in part 

 black, the inner and outer surfaces of hind pair more so; stigma of 

 wings brown, only a rudiment of a submarginal band present; pe- 

 duncle black, abdomen mostly brown-black, venter and posterior- 

 lateral areas brown. 



Head from above about three-fifths as long as broad, face only 

 feebly protruding and rounded, temples not prominent, hind edge 

 of head almost straight transversely, vertex moderately convex, eyes 

 not sharply set off from vertex and face, hence, head subrectangulate- 

 ovate; malar groove polished, cheeks feebly reticulate punctate, rest 

 of head more coarsely so, but ocellar area more finely punctured, 

 head inconspicuously and rather sparsely hairy; antennae moder- 

 ately hairy, pedicel almost a third as long as scape, and about a 

 fourth longer than Fl, latter approximately a fifth longer than 

 each of F2 to F5, latter subequal in length and diameter, each only 

 slightly longer than broad, club slightly thicker than funicular joints 

 and somewhat longer than F4 and F5 combined; prothorax almost 

 one-seventh narrower than head, and almost as broad as mesothorax, 

 pronota and mesonota coarsely umbilicately punctate, moderately 

 hairy, mesopleura finely papillose on front half, aciculate-punctate 

 on posterior half; propodeal groove broad, shallow, anterior third 

 polished, limited in front by a sharply curved carina, surface of 

 propodeum as a whole irregularly and rather coarsely reticulate- 

 rugose; 12 to 14 setae on submarginal vein; abdomen polished, 

 smooth and bare except area of ovipositor sheath, which is punctate 

 and hairy.
