(The separation of the cohors Arantus into genera is at present impo.ssible and 

 the attempt of F. Cambridge must be regarded as provisional and very imperfect, 

 since the male of some species would have to be placed under one genus and the female 

 under another, as I myself had opportunity to find. Some of the species placed in 

 this catalogue under the cohors Arantus very probabh' do not belong to it. The 

 following species have been placed by F. Cambridge.
