Obs. — Tins mimite sjx'cies is peculiar, and probably 

 generically distinct from the ordinary Scopcei ; the form of 

 the front angles of the thorax is dissimilar from what is 

 usual in Scopccns ; the general appearance is much that 

 of an extremely minute Ldtliroh'mm, but, as the structure 

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

 that genus till its characters can be more fully ascertained.
