setse. The sirperior clav: of each foot sleiuler and acumhiate, with

 The mfer-ior clmo of each foot slender and tapering, a little more 

 than half the lengtii of tlie superior claw, unarmed. A single 

 very slender tenent hair to each foot.

 On the middle of the dorsal side of the head is a prominent 

 black sagittate marking thus |, with its apex directed backwards.

This species differs from typical meuibers of the genug ^ntO' 

 mohiya, and resembles the genus Orchesella, in the very short 

 fourth abdominal segment. It agrees with the genus Entomohrya 

 in the charactex\s of the antennae and furcula, in the eyes, and 

 in the absence of post-antennal organs, J^ntomobrya anonuda 

 Carpenter * similarly possesses a relatively short fourth abdominal 

 segment. The latter species, however, may ultimately be 

 separated into a new genus on account of its possessing six-jointed 

 antenna?.
