 Pronotum simple, smooth (the posterior lobe punctulate) ; the

 posterior lobe, the hind border of latter obtusely and bluntly 

 angled ; lower border of deflected lobes very obtusely angled in 

 the middle ; tubercle of prosternum prominent, sub-cylindrical, 

 bluntly pointed, at the base laterally compressed, at least in the 

 male. Wings and wing covers about reaching the tip of the abdo- 

 men, slender. Hind femora reaching (male) or surpassing (fe- 

 male) the tip of the wing covers, moderately stout, but tapering 

 very regularly, unarmed above. Edges of inferior valve of ovi- 

 positor smooth ; anal cerci of male having the general structure

Paroxta atlantica. Scudder. 



Dull, olivaceous, excepting the top of the head, thorax and
