Tribe III. MONOHAMMINI. 



In this group of genera, the front is large, vertical, quadrate, 

 fiat; eyes somewhat finely granulate, emarginate; antenna; longer 

 than body, very long in male, except in Goes and Cacoplia, scape 

 rather stout; elytra narrowed behind or cylindrical; front coxal

 occurs.

Here belong large species with long legs, which occur upon pine. 

 The antenna 1 of the males are very long, quite roughly punctured 

 and without pubescence; those of females shorter, very much 

 smoother and clothed with a fine ash-colored pubescence on the 

 basal half of each joint from the third; except in coufusor, in which 

 the whole of each joint is pubescent : thorax with a robust spine 

 each side. Two species and one variety have been taken in the 

 State, while another may occur.
