testaceous, flagellum blackish ; legs concolorons ^vith thorax ; f orewing 

 hyaline at base and apex, distinctly infuscated behind marginal vein; 

 hind wing hyaline ; abdomen testaceous at base, dark brown to black- 

 ish on apical half or more; ovipositor sheaths testaceous. 



Head viewed from in front as long as broad ; cheek nearly straight 

 in profile; malar furrow distinct, malar space equal to more than half 

 vertical length of eye ; eyes inconspicuously pilose, converging above ; 

 frons constituting a little more than one-third the total width of head; 

 scrobes shallow, poorly delimited; frontal ledge sharply cariniform; 

 ocellar triangle obtuse; ocellocular line about equal to diameter of 

 lateral ocellus; head in dorsal view transverse; occiput slightly con- 

 cave; vertex not abruptly truncate behind, forming with occiput a 

 slightly rounded angle; lateral ocellus placed fully three times its 

 own diameter in front of occipital margin; whole head strongly re- 

 ticulate punctate; pubescence of head pale and rather short except on 

 lower part of frons along eye margins, where the hairs are longer; 

 antenna long, slightly clavate; scape cylindrical, slightly curved, 

 reaching to front ocellus; pedicel about two and one-half times as 

 long as broad; ring joint very slightly longer than broad; first funicu- 

 lar segment equal to pedicel, seventh funicular segment very slightly 

 longer than broad; club obscurely 3-segmented, obliquely truncate, 

 very slightly thicker than last segment of funicle and not quite equal 

 in length to three preceding funicular segments combined. 



Pronotum conical, about as long as broad, strongly sculptured; 

 mesoscutum about a half longer than broad, finely and almost uniform- 

 ly punctate, dull, deeply concave behind the prescutum, the concave 

 portion sculptured about like the rest; parapsidal grooves deep; pre- 

 scutum a little longer than the concave area behind it; scapulae sharp- 

 ly cariniform for a short distance posteriorly ; scutellum very nearly 

 twice as long as broad, finely reticulate punctate, dull, with many 

 short, brownish hairs scattered over its surface; axillae sculptured 

 like scutellum; mesopleuron finely reticulated and clothed with whit- 

 ish pubescence anteriorly, approximately the posterior half finely 

 longitudinally striated and bare; propodeum deeply emarginate 

 medially; metanotum with a subtriangular, translucent, flangelike 

 elevation medially adjacent to apex of scutellum. 



Forewing nearly or quite three times as long as broad ; marginal vein 

 fully twice as long as stigmal vein; postmarginal longer than stigmal; 

 costal cell mostly bare but with some weak cilia basally and with a row 

 of about 7 or 8 moderately long, straight hairs on the under surface 

 of wing near the apex of cell adjacent to the curve in submarginal 

 vein; area behind the straight portion of submarginal vein mostly 

 ciliated but with the cilia sparse distad of middle; infuscated middle 

 portion of wing clothed with short, flattened, scalelike hairs; area 

 distad of stigmal vein with normal cilia.
