 tures, and covered with fine, pale, ochreous hair; propodeal pleurae shiny, 

 finely reticulated and with sparse shallow punctures ; abdomen with its tergum 

 shining and sculptured much like the propodeal pleurae but with smaller, 

 better-defined, closer punctures, the punctures from three to six or more 

 puncture-widths apart on the first tergite, the punctures hardly closer on the 

 succeeding tergites; second, third and fourth tergites with a thin apical, 

 whitish hair-band that is interrupted in the middle; apical edge of first, 

 second, third and fourth tergites with a stramineous border; second tergite 

 with its elevated portion down the middle : depressed portion presumably 

 :: 20 : 10; fifth tergite shining, reticulate, its punctures closer and larger 

 than on the other tergites; pygidium nearly pointed at apex; tergum with 

 inconspicuous, pale, nearly erect hairs in addition to the hair-bands; fimbria 

 dark brown, appearing blackish.

 ally; joint 3 of antennae : joint 4 : : 9 : 5; joint 4 and following joints from 

 a little more than one and one-half times as long as thick to nearly twice 

 as long as thick up to the ninth joint, the succeeding joints shorter than the 

 eighth joint; antennae dullish; flagel almost straight in outline; antennae 

 blackish throughout; mandible atypical, rather heavy, extending to the outer 

 edge of the labrum and nearly to end of the basal haK of its fellow, black 

 except for the apical fourth which is mostly dull, dark reddish; palpi nearly 

 typical; thorax covered with an abundance of whitish hairs; hairs of dorsulum 

 not much shorter than hair of mesopleurae; dorsulum shiny, finely reticu- 

 lated and closely punctured, the punctures distinct and from nearly adjoining 

 to three puncture- widths apart, mostly nearly adjoining or not more than two 

 puncture-widths apart; notauli represented by a shining line; mesopleurae 

 shiny, with whitish hairs throughout, finely reticulated and mostly covered 

 with adjoining or nearly adjoining shallow pits; scutel hairy and sculptured 

 much like the dorsulum; metanotum hairy and sculptured much like the 

 dorsulum except that the sculpture is denser; tegulae brownish stramineous, 

 partly polished, mostly closely punctured; wing base mostly pale stramineous, 

 partly blackish, subcosta blackish, stigma brownish stramineous, membrane 

 uniformly tinged with brown; legs blackish brown, excepting the tarsi which 

 are rather dark brown; legs mostly covered with whitish hairs; hind metatarsi
