is intermixed with very small although distinct punctures ; 

 at the base , especially towards the outer corner , large but 

 shallow round punctures are present which are surrounded 

 by a shining margin; the mandibles are about as long as 

 the head, regularly curved on the outside, broad at the 

 base within which is a strong process which is slightly 

 emarginate at the tip; between this process and the tip 

 the mandibles are strongly curved ; about the middle a 

 broad and short tooth proceeds from the uppersurface. — 

 The head shows a sculpture similar to that of the man- 

 dibles (except on the vertex which has a smooth and shi- 

 ning space preceded by a rather inconspicuous transverse 

 impression) but the punctures are more numerous, larger 

 and deeper and behind the eyes strongly confluent ; the 

 front margin is distinctly concave and provided in the 

 middle with two rounded tubercles which are separated b}' 

 a narrow but rather deep emargination ; the lateral angles 

 rounded off, the outer margin of the ocular can thus slightly 

 concave , and the sides of the head behind the eyes slightly 

 produced into a rounded tubercle. — The prothorax is a 

 little wider than the head and rather uniformly covered 

 with strong punctures which are coarser and more or less 

 confluent on the sides and on the anterior margin; the 

 middle of the disk is strongly depressed or even slightly 

 impressed , the lateral margins are parallel , the anterior 

 angles obliquely truncated. The scutellum with a few large 

 punctures. — The elytra are strongly and closely punctu- 

 red at the base, sides and apex; each of them shows seven 

 deeply impressed striae ; the interstices between the first 

 and 5th striae are provided with three rather regular rows 

 of very fine punctures; on the first (the sutural one) and 

 the 6th and 7th interstices the punctures are more distinct 

 and more irregularly placed; the 7th interstice is very 

 narrow. 



Undersurface : the jugulum (with the exception of its 

 base) and the mentum are opaque and provided with large 

 margined shallow punctures; the sides of the head are
