 parts. Legs pale yellow, short and stout ; the tarsi short, 

 the anterior ones broad. Under surface of head impunc-

Tapajos ; a single female. 



Obs. — This minute species is peculiar, and probably 

 generically distinct from the ordinary Scojxpi ; the form of 

 the front angles of the thorax is dissimilar from what is 

 usual in ScopcBiis ; the general appearance is much that 

 of an extremely miniite Latkrohium, but, as the structure 

 of the tarsi is like that of Scopceus, it may be placed in 

 that genus till its characters can be more fully ascertained.
