I feel no doubt whatever as to the specific identity of these 
two forms, separated with considerable hesitation by 
Mr. Smith. As the female was described before the 
male, and the latter (as compared with most of its 
Hawaiian congeners) does not deserve the name 
denticornis, the species had better be called 0 . mandi- 
hularis. 
The space between the eyes is exceptionally narrow, and 
strongly concave. The head is very finely and 
smoothly punctured with scarcely any traces of 
strigosity. The eyes are facetted finely in the c?, by 
no means finely in The hind body is narrow and 
not all strongly rounded laterally. The ventral seg- 
ments of the male resemble those of the same sex in 
C. affinis.
