ie a be apes one with a dense umber-brown 
close pile with a stout spine on each side. Elytra 
with two cinereous an diverging fasciæ. The scutellar 
space usually darker brown than the rest, and always stopping 
short of and within the humeral angle 
I have come to the conclusion that Fabricius’s M. ruspator 
and Schönherr’s M. nubifer are the same species. It varies 
much in size, and somewhat in shade of colour, and in the 
markings ; but their character is always the same. 
The relations of the Old-Calabar Monohammi are to the 
Indian species, and not to the European and North-American, 
which differ from them somewhat in facies and more especially 
in texture. 'lhe genus is not represented in the Brazilian 
region, but is forlaodd by Teeniotes, Ptychodes, &c.
