more coarsely punctured prothorax, with the sides strongly 

 rounded, the less fine and more coarsely punctate elytral 

 striae, and the well defined elytral vittae. I have seen ex- 

 amples of deserhis which much resemble the present species, 

 but these may be at once separated by the broader more im- 

 pressed elytral sulci, which are much more strongly punc- 

 tured. 



In the following table of our species of Eupagoderes thus 

 far described, plumbeus Horn, has been omitted. An ex- 

 amination of the types of this and varius shows them to be 

 practically identical. Dunnianus is placed in accordance 

 with the described characters, the species being unknown to 

 me in nature.
