CHILOROGOMPHINAE. 
So far as at present known only the genus Ovogomphus 
occurs in the Indian area. ‘The other genus of the family, 
Chlorogomphus is found in Sumatra, Java and Tonkin, whilst 
Orogomphus has representatives in Bengal, Burma and the Hima- 
layas, as well as in Borneo, the Philippine Islands and Formosa. 
The subfamily is the only one confined to the Oriental region. 
Four species of Orogomphus are known. They are— 
Orogomphus atkinsonit, de Selys. Bengal, Assam. 
spectosus, de Selys. Burma, Darjiling. 
splendidus, de Selys. Philippine Islands, Bor-

ters of the male previously unknown (/oc cit. pp. 77-79).

female from Luzon is given in his 4" additions. Synops. Gomph ,
