abdominal segment; yellowish hyaline, the nervures yellowish ; 

 the second transverse cubital nervure is oblique, slightly 

 curved at the top ; the second recurrent nervure is received 

 near the base of the apical tiurd ; the base of the radius has 

 two oblique curves, the latter being slightly the larger and 

 not quite so uniformly straight. Abdomen shining, closely 

 punctured, weakly on the second, strongly on the apical seg- 

 ments ; the apical half of the pygidium is smooth in the 

 middle; the petiole is sparsely punctured; the furrow on 

 the base of the second segment is smooth in the middle. The 

 basal neck of the underside is roundly raised in the middle ; 

 the apex of the raised part is oblique and does not reach to 

 its apex.

Scape of antennae shining, sparsely covered with white 

 hair; its apex rufous ; the second joint is sliining, punctured ; 

 the others are opaque and thickly covered with white pubes- 

 cence. The ocellar region and the middle of the vertex 

 behind impunctate, the rest of the vertex and the front 

 bearing large, deep, clearly separated punctures; the vertex 

 is bare ; the front bears long black hairs ; the antennal 

 tubercles are smooth and shining. Face and clypeus closely 

 punctured. The basal depression of the pronotum closely 

 and finely rugosely punctured ; the apex bears large deep 

 elongated punctures. Mesonotum smooth ; its sides with 

 some punctures ; on the apical half are two deep, wide, 

 oblique furrows. Scutellum sparsely covered with large 

 punctures ; the postscutellum more closely and not so 

 strongly punctured. Median segment opaque, irregularly 

 closely rugosely punctured ; the middle region with some 

 distinct punctures; in the middle, extending from the base to 

 near the apex, are two not very distinct longitudinal keols, 

 which are wider apart at tiie base and the space between 

 them is irregularly transversely striated; the apical slope is more 

 coarsely rugose, more strongly at the sides than in the middle. 

 Propleurge strongly punctured, the apex closely longitudinally 

 striated ; on the upper part at the apex is an oval depression. 

 Mesopleuraj rugose, distinctly punctured above; thickly covered 

 with white hair. Metapieuraj closely striolated; the base 

 depressed, tlie depression with a few stout keels. Meso- 

 sternum shining, sparsely covered with large deep punctures;
