Type : P. sulcifrons, (Wid.). 



I have had no opportunity of examining a specimen of Platyopis 

 sidcifrons, (Wid.), but as M. Simon and Professor Kulczynski both 

 regard it as being congeneric with P. bicuspis, (Cambr.), and 

 P. diceros, (Cambr.), I am here adopting that arrangement. 

 The name Platyopis is stated by M. Simon to be pre-occupied. 

 After careful search, however, I have been unable to find that it 

 had been employed previous to Menge's Preuss. Spin. (1868), and 

 I therefore employ it in place of the generally accepted name 

 Panamomops.
