BORNEAN DRAGONFLIES. 339 



Of these genera : Chlorovemxt appears to be confined to penin- 

 sular India ; Blsparoneara has a westerly range, extending from 

 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 Cejdon ; whilst the 

 still more specialized Risioneura is Papuan (see Laidlaw^, Bee. 

 Ind. Mus. xiii. 1917, pp. 343-344).]
