This species has a peculiar facies, arising from jts 

 narrow head, with long vertex and its broad thorax. The 

 antenn;e are yellow and about as long as head and thorax ; 

 1st joint not much longer than the two following together, 

 3rd joint one and a half times as long as the 2nd, the 

 following joints slender and elongate, each a little shorter 

 than its i)redeccssor. Palpi yellow. Head longer than 

 broad, (piite one-half narrower than the base of the thorax, 

 the eyes placed in front of the middle; it is dull, sparingly 

 and rather finely punctured, and Avitli a fine rather long 

 scanty pubescence. Thorax shining reddish, at the base 

 slightly narrower than the elytra, distinctly narrowed to 

 the front, rather longer than its breadth at the base ; on 

 each side the middle with a row of fine punctures, and 

 Avith other fine punctures at the sides. Elytra rather 

 longer than the thorax, shining, red at the base, the rest 

 inliiscate, each with four or five rows of very fine punc- 

 tures ; these, Avith the exception of the roAV close to the 

 suture, being very indistinct. Hind body distinctly and 

 not altogether sparingly jnmctured. Legs yellowish. 



In the male the hind margin of the sixth segment 

 beneath is distinctly emarginate in the middle, and the
