StaphijlinidcB of the Amazon Valhnj. 393 



Amazons; a single individual .vithont special locality 

 I have named this species m honour of M. Albeit 

 Fauvel,of Caen, whose \^honr, on the Starhfin^^^^ 

 weU known to all interested in this family of Coleoptera. 



Bledius. 



The species of this well-known genus here described 

 are seven in number, and suggest no special remark; only- 

 one species was found by Mr. Bates, the other six being 

 discovered by Dr. Trail. Only t iree or four species have 

 been previously described from South America, yet it is 

 very probable that the genus is numerously repie.ented 

 there, for these insects are very retiring m their habits 

 and little likely to come under the notice of collectors, 

 except special search be made for them.
