* 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. 



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

 that I have placed it under No. 20. 



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

 sionally and with hesitation.
