seemingly sculptureless except for distinct punctures that are appar- 

 ently at most not more than two puncture widths apart, clypeus 

 convex, almost gabled down the middle, with a broad highly polished 

 clypearea somewhat like in A. (A.) miserabilis Cresson, on each 

 side of the clypearea and above the latter the clypeus is mostly 

 finely reticulated and punctured, the punctures mostly two to three 

 puncture widths apart, clypeus almost bare, labrarea triangular, 

 pointed at apex, at most between one-third and one-fourth as 

 long down the middle as wide at base, labrarea apparently not more 

 than one-third as wide as the labrum, the latter with a fringe of golden 

 hairs, length of malar line : length of joint 3 of antenna; :: 2 : 8, 

 the elevated portion of the malar space apparently no longer than 

 the depressed portion, mandibles typical, robust, not extending to 

 the outer edge of the labrum, with their basal half black, the apical 

 half mostly reddish castaneous, palpi slender, nearly typical; thorax 

 covered with whitish hairs throughout, dorsulum finely reticulated, 

 its punctures shallow and from two to six or more puncture widths 

 apart, notauli represented by impressed lines, scutel with its anterior 

 half mostly polished and sparsely punctured, its posterior half finely 

 sculptured, metanotum indefinitely sculptured, tegulae pale brownish 

 stramineous, wing base darker, subcosta blackish brown, costa 

 dark brown, stigma pale yellowish brown, rest of veins dark brownish 

 stramineous, membrane with a strong brownish tinge, second sub- 

 marginal cell distinctly shorter than the first, second abscissa of 

 cubitus apparently hardly longer than half of the length of the first 

 transverse cubitus and about one-fifth the length of the third abscissa 

 and exactly as long as the fourth abscissa of the cubitus, nervulus 

 received by the median cell and forming an acute angle with the 

 second abscissa of the median vein, legs black covered with whitish 

 hairs, hair of tibiae and tarsi rather ochreous, scopa compact, mostly 

 whitish, brownish at base, most of its hairs branched, tarsi and claws 

 dark brownish stramineous; propodeum with its enclosure poorly 

 defined, funnel shaped, finely reticulated, upper aspect of propodeum 

 outside of the enclosure finely and coarsely reticulated, pleurae of the 

 propodeum finely reticulated and with a few punctures; abdomen 

 shining, almost polished, delicately reticulated, more finely and 

 sparsely punctured than the dorsulum, second tergite depressed 

 between one-third and one-fourth, abdomen inconspicuously covered 

 with fine whitish hair, second, third and fourth tergites with a distinct 

 apical fringe of white hair that is interrupted in the middle of the 

 second and third tergites, apical margin of fourth tergite brownish,
