NATURAL SCIENCES OF PHILADELPHIA. 



Size small; form very distinctly compressed. Iload with the vertex 

 regularly declivent to the narrow l)ut low fastigium; eyes ovate, small 

 but rather prominent; anteniuo slightly more than twice the length of 

 the body proper, rather thick in the proximal portion. Pronotum 

 with a moderate mesad constriction; in length slightly more than 

 twice that of the head; cephalic margin truncate, caudal margin very 

 faintly obtuse-angulate, lateral lobes shallow, the greatest depth con- 

 tained slightly more tlxan twice in the length. Tegmina very short, 

 the extreme apex alone visible beyond the caudal margin of the pro- 

 notum. Styles very short, thick, conic; ovipositor about equal to the 

 cephalic femur in length, the proximal third nearly subequal in width, 

 from which, however, it gradually enlarges to the distal section, which 

 is distinctly but not greatly broader than the proximal portion; the 

 caudal margin is strongly curved dorsad in the distal portion, the 

 extreme apex, being rounded and nearly dorsad in position, all the 

 margins unarmed; subgenital plate with a small but deeply and 

 strongly rounded apical emargination. Cephalic limbs slender, the

bullae quite small; median limbs slightly longer than the cephalic. 

 Caudal femora nearly two and one-half times the length of the cephalic 

 femora, well inflated in the proximal half; caudal tibire exceeding the 

 length of the femora 1)V nearlv the dorsal length of the head.
