ampliated from base to apex, flattened outwardly, broadly scooped 

 inwardly, and the inner edge is bluntly dentate at about two-thirds 

 of the length and emarginate under the tooth, the apices are mode- 

 rately shai^p but not mucronate, and there is a small apical spur ; 

 hind claws single, simple. 



Female : Like the male, but the three bands of scales on the elytra 

 are very distinct. 



Length 5J-6 mm. ; width Sh mm.

Male : Black, with the elytra chalybeate and shining, antennae and 

 legs red ; prothorax partly covered with j-ellowish, elongate scales, 

 denser and smaller along the base, where they form a band, some- 

 what ii-regularly disposed on the disk, but partly filling the median 

 longitudinal groove, scutellum covered with small scales ; elytra with 

 very elongate whitish scales not closely set but very numerous and 

 somewhat seriate ; propygidium, pygidium, and abdomen with 

 similarly elongate whitish or yellowish scales looking almost like 

 appressed squamose hairs, and also set not veiy close to each other ; 

 head very rugose, clypeus with the outer angles broadly rounded, and 

 the anterior margins slightly reflexed and scarcely emarginate in the 

 •centre ; prothorax gradually ampliated laterally in the middle, having 

 on each side of the disk some deep punctures filled by the scales, as 

 well as smooth intervening spaces, but closely and finely punctate on 

 •each side of the base, the anterior and lateral margins are fringed 

 with very long, somewhat dense, fulvous, bristly hairs, the elytra are 

 roughly punctate and not costulate, and although attenuate laterally 

 towards the apex, not strongly sinuate past the humeral part ; 

 anterior tibite bi-dentate ; posterior femora swollen, moderately 

 robust, simple but with the trochanters produced into a short, shai^p 

 spine ; hind tibiiB moderately robust, convex outwardly, flattened 

 inwardly, concave thence towards the apical part where they end in a 

 sub-mucronate process on each side, the upper one being the more 

 developed of the two ; hind claws with a very distinct tooth under- 

 neath, no apical spur to the posterior tibiae. 



Female : Like the male, but the anterior tibiae have a very small, 

 basal outer tooth, and there is no tooth under the hind claws. 



Length 7^9 mm. ; width 4-4^ mm.
