Genus Chloroneura, nov. 



This monotypic genus, which is peculiar to Central India, 

 ranges apparently from the neighboarhood of Bombay, through the 

 West Ghauts as far at any rate as Nagpur in the Central Provinces, 

 but the limits of its distribution are not at all known. 



It is perhaps more primitive than the true Disparoneura, to 

 which it is very closely allied. The form of the anal appendages 

 of the male and of the posterior prothoracic margin of the female 

 of the two genera are extremely similar.

Genus Disparoneura, Selys. 



The type of the genus was a species identified by Selys in his 

 Synopsis as the Agrion glaucum of Rambnr. Unfortunately 

 Rambur's species turns out to be an Enallagma (see Calvert, 

 Trans. Amer. Ent. Soc., XXV, p. 40 ; 1898). 



Hence at the present time some doubt exists as to the type 

 species of the genus. Selys, however, gives Agrion frenulatum, of
