Piothoracic keel dull, very short, being scarcely longer 

 than the tubercle on each side of it, apex depressed, 

 narrow. Elytra with moderately large tubercles, 

 apical rather thick, divergent ChevroIati,\\a.terh. 



Similar to the preceding but smaller, prothorax not so 

 decidedly bulged out in the middle; apical tuber- 

 cles of elytra more triangular and proportionally 

 longer; femora decidedly shorter Jekeli, Waterh. 



The smallest of the group; similar to the two preced- 

 ing, but with prothoracic carina more distinct and 

 longer, apical bifurcation very sharp, apex scarcely 

 depressed ; without strong tubercles on elytra 

 except at base (where in the two preceding they 

 are absent), apical tubercles similar to those of 

 the preceding astheniatus, n.sp.
