the lower edge of the labrum where it is brownish, fovea with 

 whitish pubescence, fovea nearly three-fourths as wide along the 

 ocellocular line as the latter is long, hardly separated from the 

 eye margin where the ocellocular line joins the latter, fovarea not 

 trenchant, impunctate but represented by a shining space that 

 is widest and almost angulate at a point nearly half way between 

 the anterior ocellus and the antennal line, fovea apparently extending 

 a little below the clypeal line and distinctly extending far below the 

 antennal line, clypearea present, the punctures on each side of it as 

 many as five or more puncture widths apart, elsewhere on the clypeus 

 the punctures are from adjoining to one and two puncture widths 

 apart, clypeus convex, polished, indistinctly or not at all reticulate, 

 mandibles almost entirely blackish or entirely blackish, palpi typical, 

 joint 3 of antennae slightly though distinctly shorter than joints 

 4 + 5 or joint 3 : 4 + 5 :: 7 : 8, antennae blackish brown, labrarea 

 truncate, subemarginate, apparently half again as long down the 

 middle as wide at apex and at least three times as wide at base as at 

 apex; thorax black, with whitish pubescence that has an ochreous 

 tinge on the dorsal surface, dorsulum shining, reticulate and dis- 

 tinctly punctured, the punctures from nearly adjoining to five or 

 more puncture widths apart, scutel sculptured like the dorsulum, 

 metanotum more densely sculptured than the scutel, legs pubescent 

 like the thorax except that the hairs are mostly darker with a 

 golden to brownish golden tinge, scopa pale golden, its hairs not so 

 dense as to obscure the tegument, the arrangement and character 

 typical, tarsi rather pale brown except the metatarsi which are 

 very dark brown, hind femora with golden brown hairs at apex, 

 tegulae brownish stramineous, wing base blackish, stigma dark 

 brown, subcosta blackish, veins brownish stramineous, membrane 

 with a brownish stramineous tinge, first recurrent vein received 

 by the second submarginal cell nearer the second transverse 

 cubitus than the first transverse cubitus is to the stigma, nervulus 

 received by the median cell, nearly interstitial and forming an acute 

 angle with the second abscissa of the median vein; propodeum 

 regulose except for the enclosure which is plicate, somewhat as in A. 

 (Scrapter) cratcegi Robertson, enclosure defined by the difference in 

 sculpture and with a median longitudinal low crista; abdomen pol- 

 ished, black, without a metallic tinge, depressed portion of tergites 

 brownish, the tergites covered with setigerous punctures that are 

 seemingly sparser and distinctly smaller than on the dorsulum; 

 abdomen appearing bare without fasciae, its pubescence whitish
