Clarence River, Tamwortb, N.S.W. (Mr. A. M. Lea). 



This species differs from nigricornis by the head more elongate, 

 the antennae longer and the impressions of the 1st dorsal segment 

 small and without carinse. 



One specimen (£) from Tamworth has the abdomen piceous- 

 black and shorter, the elytra less attenuate at the base and the 

 shoulders less oblique, the head shorter, and the joints of the 

 antenna? 9-10 a little longer; the body is stouter. Long. 2-50 mm. 

 The <J being unknown, I dare not consider this insect as a 

 distinct species.
