separated in both sexes by the width of the mesothoracic trochanters; 

 metasternal lobes either closely approximate (c?) or as distant as the 

 mesosternal lobes (■?). Tegmina and wings about reaching the tip of 

 the abdomen, slender. Hind femora reaching (c?) or surpassing (?) 

 the tip of the tegmina, moderately stout but tapering very regularly, 

 unarmed above, the genicular lobes produced but rounded ; spined 

 margin of hind tibia? smooth, scarcely dilated toward the tip. Edges 

 of inferior valve of ovipositor smooth; anal cerci of male having 

 the general structure of those of Caloptenus. 



This genus bears a close general resemblance to the gerontogeic 

 Oxya Serv., but differs strikingly from it in the separated metasternal 

 lobes of the female, the blunt tips of the genie ulations of the hind 

 femora, and the want of lateral carinae on the upper surface of the 

 hind tibiae. 



62. Paroxya atlantica. Dull olivaceous, excepting the top 

 of head, thorax and tegmina, which vary from light to dark brown. 

 Head olivaceous yellow on face and sides, in the female more or less 

 infuscated ; above the antennae brownish fuscous, more or less tinged 

 with castaneous; behind the eye a broad, straight, horizontal, black 

 band, edged more or less distinctly, both above and below, with yel- 

 lowish; antennae not half so long as the body in the male, pale yellow 

 at base, at least in male, beyond testaceous, deepening into fuscous 

 toward the tip. Upper surface of pronotum of the color of the top 

 of the head, the upper half of the deflected lobes with a very broad 

 black band, in continuation of that on the head, anteriorly edged 

 more or less distinctly, both above and below, with yellowish, and 

 fading out before, or abruptly terminating at, the posterior lobe; pleura 

 with a horizontal stigmatal stripe running backward from the hinder 

 edge of the mesothoracic episterna (sometimes confined to the meso- 

 thoracic epimera), and an oblique stripe nearly following the division 

 line between the metathoracic episterna and epimera; when the lower 

 stripe is complete it renders the metathoracic episterna conspicuous, 

 especially in the male, on account of the wedge-shaped oblique yellow 

 dash which lies between these two black stripes. Tegmina nearly uni- 

 form brownish fuscous, with a faint line of small fleckings down the 

 middle in the female. Legs of the color of the body, the middle and 

 hind femora generally more or less infuscated on their outer face, the 

 upper half of the genicular lobes of latter black ; hind tibiae glaucous 

 with black or blackish spines. Length, cf, 21 mm., ?, 28 mm.; of an-
