Cylindrical, reddish brown, shining ; the head and rostrum 

 microscopically transversely strigose, with a few punctures

 punctuation rather close behind the head and gradually 

 becoming tine and more sparing to the base, well behind the 

 neck are two small tubercles, and in front of them the thorax 

 is triangularly flattened; the elytra are reddish, with two 

 dark patches which apically leave a narrow red margin; the 

 pygidia are punctulate ; the presternum, keel parallel laterally 

 and markedly earinate along its edge, truncate anteriorly and
