Of these genera. : Chloroiieura appears to be confined to penin-

 Africa to India and Burma and reaching its limit eastwards in 

 Borneo ; Caconeura, more specialized in some respects, extends 

 from Burma to Malaya, with one species in Ce3don ; whilst the 

 still more specialized Risioneura is Papuan (see Laidlaw, Rec.
