The synonymy of this species has been partly established 
by Kirby and given nearly in full by I. Bolivar in his recent 
paper on the Indian fauna (l.c. 1918). I can only confirm 
this synonymy after study of Walker’s types, and add one 
new synonym—Acridium scitulum Walker. 
This species is easily distinguished from E. plorans by 
the lack of a median carinula on the vertex. This carinula 
is present in all the known African species that form 
a natural group with HL. plorans. It is interesting, there- 
fore, to record that in the British Museum there are two 
female specimens of Huprepocnemis (one from the Blue Nile, 
the other from Abyssinia) which also have no carmula on 
the vertex; since, however, the material is so scanty, I 
do not venture either to describe these specimens as a 
new species or to identify them with H#. alacris, though 
they very much resemble this species.
