Size small ; colour black : the whole body punctulate, with 

 a few stiff hairs. Antennte with 9 segments, 2nd reddish, 

 7th and 8tb white, the rest black ; first long, second shorter, the 

 rest quite round, as broad as long, gradually larger, the ninth a 

 little smaller than the eighth, which is the largest. Pronotum 

 broader than the head, elongate, the sides parallel and raised : 

 mesonotum narrow, strongly impressed anteriorly, the posterior 

 part being therefore slightly elevated, the sides keeled and the 

 anterior angle slightly broader than the pronotum ; metanotum as 

 broad as the mesonotum, and exposing only a small part of the 

 first abdominal segment. Legs long ; tibiae and tarsi testaceous ; 

 femora testaceous, with a strong broad black band ; first tarsal 

 segment longer than the second and third together. Abdomen 

 cylindrical, the lateral tubercles very distinct on the second and
