PAUSUS. 
able to find any more speeimens, I was prevented 
from ascertaining the fact by reiterated experi- 
ments at dilferent times; which I therefore must 
recommend to other naturalists who may have an 
opportunity of visiting Sierra Leona, reijuestiiig 
tliat they would jiarticultirly inquire into this 
curious circumstance. 1 shall now only add some 
few remarks, shewing in w hat manner this new 
species differs from the old one. Not being quite 
so broad, it looks as if it were longer, and more 
cylindrical; it is also of a lighter or chesnut colour, 
and all over very glossy. The head is larger, but 
its annular base part smaller, and contracted: it 
is furnished wath a little horn in the middle, be- 
tween the eyes, wdiich is strait, conic, and tipped 
with a tuft of cartilaginous hairs: the clypeus is 
only depressed, and the jugular triangle wider: 
the ejms are large, and very evident, those of the 
male black, tliougli in a certain light appearing 
greenish; but those of the female are like pearls, 
or as if they wmre covered wdth a crystalline mem- 
brane: the angles of the brim of the socket are 
small and rounded at the top, and the hinder one 
low^er than the eye. The pivots of the antennas 
are not so discernible as in the former species, 
being like the surrounding jrarts in colour: the 
under joint is without any hairy papilla or wart; 
the upper joint or clava is of the size of the head, 
quite globular, and resembles an inflated bladder, 
being almost pellucid, and of a light flesh-colour; 
the keel is nothing more than a raised line, finish- 
ing on the vertex in only one chesnut-brown
