the middle broadly projecting in the centre, the apex transverse, finely punctured, 

 except at the extreme base, fringed at the sides and at the middle with long fulvous 

 hair ; the mandibles rufous, black at the base and apex, and fringed with long fulvous 

 hair. The antennae have the scape punctured and covered with long white hair, the 

 flagellum, especially on the lower side, with a pale pubescence. The pronotum with 

 large punctures at the base, densely covered (especially at the base) with long pale hair; 

 the pleurae obliquely striated beneath : the upper part impunctate. The mesonotum 

 with the middle strongly punctured, the sides with a pair of punctures at the base and 

 apex ; the apex with pale fulvous hair, this being also the case with the scutellum, 

 which bears scattered punctures, except in the middle ; the postscut ellum with 

 scattered punctures. The median segment shining, impunctate, the apex alutaceous ; 

 the central keel straight, the lateral keels curved; the meso pleurae rather strongly 

 punctured, the metapleurae strongly obliquely striolate. The abdomen shining ; the 

 basal segment sparsely, the apical segment more strongly and closely, punctured; the 

 furrow at the base of the second segment deep, crenulated at the sides ; the second 

 and following segment fringed with long pale hair ; the hypopygium coarsely punc- 

 tured, thickly covered with long white hair, the extreme apex rufous ; the ventral 

 surface punctured and haired like the dorsal surface. The legs are thickly covered 

 with long silvery hair ; the spines on the apices of the tarsal joints are rufous ; the 

 three spines on the metatarsus are black. The wings have some hyaline lines and 

 spots ; the first recurrent nervure is received beyond the middle, the second close to 

 the apex of the cellule.

Head strongly punctured, the punctures not confluent; the oral region and the 

 cheeks over the antennae less strongly punctured ; the ocelli in deep pits ; covered 

 with long pale fulvous hair ; the clypeus fringed with golden hair, the apex depressed, 

 impunctate ; the mandibles ferruginous, black at the base and apex, fringed with long 

 golden hair. The scape of the antennae with large punctures and covered with long 

 golden hair, shining; the flagellum covered with a microscopic pubescence, fuscous 

 beneath, the third and fourth joints subequal. The pronotum strongly punctured, 

 except a semicircular space at the apex, which is smooth and glabrous, the punctured 

 part being covered with longish hair ; the oblique base is finely punctured and pilose. 

 The mesonotum has large, scattered, widely separated punctures and a scattered 

 pubescence. The base of the scutellum is smooth and glabrous, the apex punctured, 

 and bearing long pale fulvous hairs ; there runs down the middle of the punctured
