DIMECOENIA n. gen. 



This genus is proposed for the reception of Caenia spinosa 

 Loew, its type species. It differs from Cocnia, as based on 

 its genotype, Ephydra palustris Fallen, in the absence of pul- 

 villi and having the claws long and nearly straight. In these 

 respects it resembles Ephydra, but in the present genus there 

 are only two frontal orbital bristles and no post-humeral or 

 prescutellar bristles. The pre-frontal bristles are strongly 

 developed. The genus seems intermediate between Cocnia 

 and Ephydra but is constant in the characters mentioned. 



Here also belongs Ephydra austrina Coquillett, of which 

 Caenia virida Hine is a synonym. I have examined the cotypic 

 series of Coquillett's and Mine's species. It is strange that 

 both authors overlooked the characteristic tufts of hair on the 

 hind tarsi of the male of this species. This is described by 

 Aldrich in his paper on "Two Western Species of Ephydra."*
