Mr. Cameron's description requires no supplement beyond 
a word as to the differences between this and other 
species (not in Mr. C.’s possession), and a remark on 
the male. 
The eyes are rather close to each other in front, though a 
little more separated than in G. mandihularis, Smith ;

0. affinis. The hind body is similar in shape to that 
of G. mandihularis. 
In the male the antennal sexual characters are almost as 
in G. mandihularis, while the ventral depression 
extends quite evidently from the middle of the 3rd 
segment to the apex.

Long. 11 mm. 
The space between the eyes is much as in the preceding 
species, the granulation of the eyes being a little 
coarser than ^ mandihularis. Smith. The head is 
very finely and closely punctured and is clothed with 
longish fuscous hairs. The prothorax and mesothorax 
are finely and closely (but not very smoothly) 
punctured and are clothed with fuscous hairs. On
