The head has the punctuation very fine but distinct, the 

 punctures moderately close together, the front margin nearly 

 smooth. The thorax has the punctuation very fine and mode- 

 rately close, the posterior part of the disk almost impunctate ;

 The elytra have the striee very distinct, the punctures in them 

 not very close together. The legs are pitchy red. The club 

 of the antenna? pale rusty testaceous. The underside of the
