that below antennae yellowish white, the cheeks with a pale whitish pubes- 

 cence and the surface slightly shiny and finely punctured. Malar space so 

 short as to be almost wanting. Antennae black, with the flagellum below 



beyond the second joint dull brownish to ferruginous, its basal joint but a 

 shade, if any, longer than the second. 



Thorax above very densely covered with a short, erect, bright fulvo- 

 ochraceous pubescence, wholly concealing the surface, not at all mixed with 

 dark hairs, longer and denser on postscutellum, paling on the sides to 

 grayish white below. Prothoracic spines apparently wanting, mesothorax 

 evenly punctured on a shining surface, the punctures very close and 

 distinct, slightly sparser on a discal space, the posterior margin very finely 

 and densely punctured. Scutellum polished and impunctate at base, else- 

 where with close, coarse, rounded punctures, the postscutellum dull and 

 finely roughened. Superior face of metathorax separated from the posterior 

 face by an irregular rim, and divided into a series of about a dozen shining 

 pits^ which are narrow, crowded and imperfect on the sides, but quite 

 perfect and about square medially. Posterior face with the sides shiny, 

 weakly and scatteringly punctured, with long, pale ochraceous hairs 

 becoming very dense laterally, the enclosure funnel-shaped, highly polished 

 and shining, the bowl more or less ridged at the sides and base, the neck 

 perfectly smooth, much longer than wide at base. Pleura shiny, with fine 

 crowded punctures concealed by a dense ochraceous pubescence. Tegulge 

 pale testaceous. Wing short, hyaline, the nervures and stigma honey 

 yellow. Legs slender, black, sometimes tinged with brownish on tarsi and 

 ends of tibi?e, the pubescence short, sparse, grayish white. Front cox?e 

 with long hairy spines. Outer tibial spurs distinctly pectinate, yellow. 

 Claws dark, medially toothed. Abdomen with the sides subparallel, 

 above densely covered with a very short and appressed and ochraceous 

 pile which conceals the surface, the first segment with long dense ochra- 

 ceous hairs at base and sides, its middle more sparsely pubescent and 

 partially exposing a shining impunctate surface. The apical margins of 

 the segments are not depressed, but have the pubescence much denser than 

 elsewhere, forming noticeable fasciae concolorous with the rest of the 

 pubescence, the venter with very narrow pale fasciae or fringes on the 

 apical margins, apical segment bare, contrasting,
