272 THE GENERA AND SPECIES OF AMYCTEEIDJE, 



rostrum which extends to the forehead. The crest is small, but 

 rather acute and pointed a little backwards. The tubercles on 

 each side of the dorsal line of the thorax are elevated, round, 

 glossy, and about five in number, while the sides are armed 

 with two strong acute tubercles, the anterior one having a 

 smaller one on its anterior and posterior sides. The elytra are 

 rather ii'regularly granulate, are strongly tuberculate, and have 

 their apex veiy minutely mucronate and slightly dehiscent. 

 The female, which is much broader than the male, has a double 

 row of granules on each side of the suture.
