Colour (in alcobol) uniform pale brown above ; upper part of bead

 and quadrate with rounded angles, defined from the upper part of the

 longitudinally. 



Antennce short but thick and clavate, the sixth segment the largest, 

 the seventh nearly as large as the fifth.

 surface very convex, the keels rising low on the segments and directed 

 downwards ; the first tergite narrower than the second, but much 

 wider than the head and covering it, its anterior border evenly 

 convex from apex to apex of keel, its posterior border nearly straight, 

 covered throughout with tubercles arranged irregularly in 5 or 6 

 rows ; the keel-bearing part of the rest of the segments covered with 

 large tubercles which are arranged in three transverse rows, in some 

 of the segments there are also indications of a fourth row of smaller 

 tubercles ; the anterior margin of the keels is defined by a sulcus but 

 is unarmed, the antero-lateral angle is obtuse and rounded, the postero- 

 lateral angle is sharp and produced, the posterior border being 

 slightly concave, the lateral margin bears five or six sharp teeth, and 

 the posterior margin also five or six more or less quadrate teeth, the 

 keels of the nineteenth do not project so far posteriorly as the 

 extremity of the anal segment ; the sides of the anal segment meeting

 sulcate towards the lateral margin. Sterna deeply sulcate longi-
