A smallj rather broad species, sparingly punctured 

 and pubescent, and yet but little shining, from the fact 

 that the surface between the punctures is very finely 

 coriaceous. The antennae are short and moderately 

 stout, considerably thickened from the third joint to the 

 apex, pitchy in colour, with the three basal joints yellow- 

 ish ; joint three more slender than two, but nearly as 

 long, four small, about the width of three, nearly as 

 long as broad, five to ten transverse, the first of them 

 slightly, the last of them rather strongly so; eleventh 

 joint stout, as long as the two preceding. Head rather 

 narrower than the thorax, broad, very indistinctly punc- 

 tured, the parts of the mouth testaceous. The thorax is 

 a little narrower than the elytra, transverse, its breadth 

 about twice its length, the sides rounded at the anterior 

 angles, finely and sparingly punctured and pubescent, 

 with an indistinct longitudinal channel in the middle. 

 The elytra are about a third longer than the thorax, 

 rather more distinctly and closely punctured than it. 

 The abdomen has segments two to four sparingly and 

 moderately finely punctured, five and six nearly impune- 

 tate. The legs are yellow, the posterior tarsi stout, and 

 moderately long, the basal joint very short, the terminal 

 one about as long as the four preceding. 



In the male, the front of the head is indistinctly chan- 

 nelled, the hind margin of the dorsal plate of the seventh 

 abdominal segment is furnished with four teeth, of about 

 the same length ; the middle ones are broad and rounded, 

 and near one another, so as to appear as if forming a 

 central, rather produced, lamina, with a notch at its 

 apex; the lateral teeth are fine and pointed.
