Antennas covered with a silvery down, the third joint 

 about one-fourth longer than the fourth ; the fourth and 

 fifth slightly curved on the lower side. Front and vertex 

 opaque, finely punctured. Front ocellus situated in a pit ; 

 the front before it raised on either side into a roundish 

 elevation, the two being separated by a furrow, at the end 

 of which is a fine straight keel, which reaches near to the 

 base of the antennae. Eyes at the top separated by the 

 length of the third and fourth joints united ; below reaching 

 to the edge of the clypeus ; below the antennae they are 

 separated by about the length of the second and third 

 joints united ; clypeus slightly concave, the apex scarcely 

 rounded, being straight to near the centre. Palpi testaceous 

 at apex ; mandibles rufous at tips. The pubescence on the 

 front and vertex is fuscous and very short, on the rest of 

 the head long and silvery white, being especially close and 

 thick below the antennae. Thorax shining, almost impunc- 

 tate and with a plumbeous tinge ; the mesonotum bears a 

 sparse short pubescence ; the pleurse and sternum are more 

 densely covered with longer silvery white hair. At the end 

 of the metanotum there is, in the middle, a bell-shaped 

 depression ; the median segment is deeply depressed in 

 the middle, the depression being widest at the base and 

 continuous with that at apex of metanotum ; its sides are 

 striated. Petiole dilated at the apex and nearly as long as 

 the thorax, and considerably longer than the second and 

 third segments united. The second segment is a little 

 shorter than the third. Legs pruinose, the coxfe bearing 

 longish silvery hair ; the femora are sparsely haired.
