 backwards, forming an acute angle; elytra not 



distinguished by sericeous pubescence umbrinus. 



94 j Thorax with posterior angles projecting slightly 

 backwards, the angle not acute but right-angled ;

 in different lights shows like a light band across 

 them scitulus.

f Not having seen this species, I only place it under No. 19 provisionally, 

 the description given by M. Kraatz being scarcely sufficient to satisfy me 

 as to its place. 



X Not having seen the male of this species, it is only from supposition 

 that I have placed it under No. 20. 



* Not having seen badius nor brunneus, their place is marked provi- 

 sionals and with hesitation.
