R. flavipennis Lea, but the armed front angles of the 
prothorax are distinctive. The clypeal suture is rather 
ill-defined, but as there is a faint depression at its position, 
and there are some distinct punctures close behind this 
and some more about the base, it might, in my table of 
the genus, be referred to Ak and associated with R. bima- 
culicollis Lea, to which it is not at all close; but regarding 
it as belonging to kk it would be associated with R. copei 
Lea, which has considerably larger eyes, pale prothorax, 
ete. The two may be thus distinguished. 
Distance between eyes less than transverse diameter of an eye. 
: R. copet Lea. 
Distance more than transverse diameter of aneye . &.cyrtops Lea.
