 punctured, rather sparsely on the occiput. Thorax and median 

 segment rather strongly punctured, the median segment much 

 shorter than the prothorax and obliquely truncate. The two 

 basal abdominal segments rugose, the first with a transverse 

 carina before the apex; the second and third with a smooth mark 

 on each side near the apical margin. Third, fourth and fifth 

 segments finely punctured, the punctures at the base of the seg- 

 ments very minute. Epipygium rugulose, narrowl}^ rounded at 

 the apex, with fulvous pubescence. Head and abdomen black; 

 thorax, median segment, legs, antennae, mandibles and epipygium 

 dull ferruginous. Length 9 mm.

 margin raised. Mesothorax sparsely punctured on the disc, 

 finely and closely on the sides between the sulcse. Scutellum
