Genus V. ERETMAPODITES, Theobald 



(Moriog. p. 280). 



This genus has been instituted by Mr. Theobald for the 

 reception of a peculiar species, bred out by Mr. Austen from 

 larvae found at Sierra Leone in old tins containing rain water. 

 It presents some resemblance to Sabethes in having the hind feet 

 provided with a peculiar paddle-shaped expansion formed of long 

 scales, but it is only the males that are so furnished, and even in 

 them, the scales are so deciduous that they are often wanting 

 even in fresh specimens.
