The species on which I found this genus is at once recognisable 
by the remarkable spiniform development of the ocular lobes. 
What are its affinities is a very dificult question. In general 
appearance it is remarkably lke Orichora (figured by Mr. Pascoe 
Journ. Linn. Soc. X. t. 19, f. 3) but has nothing to do with it 
structurally. My inclination would be to associate it in the 
Rhyparosomide with Mandalotus (probably identical as I have 
already pointed out with Dysostines), but its comparatively long 
metasternum seems quite irreconcileable with such a place. I 
have therefore referred it to the tribe in which a strict observance 
of M. Lacordaire’s tabulations would locate it and have associated 
it with the Aterpides. Certainly its rostrum is considerably like 
that of a Rhinaria, but some of the characters cited above (e.g., 
the cavernous corbels of its hind tibiz) are by no means sug- 
gestive of an Aterpid. Probably M. Lacordaire if it had been 
before him would have treated it as representing a distinct tribe. 
The peculiar scrobes of the rostrum call for special notice; a 
deep lateral sulcus runs from the apex of the rostrum hindward 
and somewhat behind the middle suddenly widens and is deflected 
to the under surface, the antenne being inserted at the point of 
deflection.
