 ally increasing in length. The prothorax is strongly constricted in front, 

 less behind, and the base is as wide as apex; the sides are obtusely angu- 

 lated and the disk bears four tubercles arranged in a square. They may 

 be known as follows: 



Larger species, thoracic tubercles very prominent tuberculata. 



Smaller, thoracic tubercles feebly developed . debilis.
