tubei'cles obtuse ; disk uneven, punctured posteriorly and on the 

 lateral tubercles as well as along the fore and hind margins. 

 Elytra narrow and only slightly tapering, the apices slightly trun- 

 cated, punctured moderately over the basal half and on the disk 

 to the apex. The pile is of a dingy yellowish olivaceous colour, 

 varied with a paler shade, which forms three obscure semi-belts 

 on the elytra. Legs and under- surface ashy-brown. 

 Ega, on dried branches.

Head and antennae brown ; base of each antennal joint (from 

 the fourth) grey : eyes distant on the vertex. Thorax with the 

 disk nearly even ; a few punctures on each side, besides those on 

 the fore and hind margins. The elytra have the shoulders more 

 produced and pointed than in the allied species, they have a few 

 punctures near the base, and the apices are singly rounded : the 

 broad grey belt across the basal half has its fore margin arched 

 posteriorly, so as to leave a space around the scutellum dark 

 brown ; it passes beneath entirely over the mesosternum : the 

 grey and brownish waved lines on the apical half are obscure 

 and silky. Body beneath and legs pitchy-brown, clothed with 

 ashy-brown pile.

 generally touching the suture. Under-surface of the body
