In the course of working out my collections, I found this 
genus in a very unsatisfactory state of confusion, and thought 
it well worth while to examine all the species carefully as a 
guide to their African distribution. 
The following list may be found useful. 
Great difficulty has 
arisen from the new species which have been described in the 
interval betwixt writing and reading the paper :—
