thickened towards the extremity: 1st joint rather stout, 

 about as long as the four following together ; 3rd joint 

 slightly shorter than 2nd, 4 — 10 each slightly shorter and 

 thicker than its predecessor, the 10th slightly transverse ; 

 last joint about equal to the 10th. Head about as broad 

 as the elytra, the front part much produced, the eyes 

 placed at the middle of the sides ; behind these it is nar- 

 rowed and rounded, so that the hinder angles have entirely 

 disappeared ; the front part is quite dull, from a very dense 

 and obsolete punctuation, the hind part almost impunctate 

 and shining. Thorax not quite so long as the head, hardly 

 half as broad as the elytra, quite twice as long as broad, 

 the front third much narrowed, extremely finely, scarcely 

 visibly piuictured at the base, with an obscure, broad, 

 double impression. Elytra longer than the thorax, darker 

 in colour at the base than at the apex, closely and finely 

 punctiu-ed, but more distinctly so than the rest of the body. 

 Hind body extremely densely and finely punctured. Legs 

 rather long ; 1st joint of hind tarsi about twice as long as 

 the 2nd.

 a little behind the middle, the sides straight behind the 

 eyes, the hind angles a little rounded ; it is quite dull, of
