Sostea cyanoptera. 

 S. ovata, atra, nitida, setosa ; scutello triangulari ; elytris laete cyaneis ; 



pedibus ferrugineis. 

 Hab. Borneo (Sarawak). 



Ovate, shining black, with moderately long setose hairs ; prothorax 

 finely punctured ; scutellum triangular ; elytra rich ultramarine blue ;

cordato ; pedibus rufo-ferrugineis.
