Bruner: South American Acri dea. 95 



( General form slender, the tegmina and wings somewhal abbreviated, 

 mn quite reaching the middle ol the genicular area of the hind femora, 

 the former rather narrow and gently tapering apically, the apex 

 rounded. Head rather large, broad, and not especially high, verj 

 perceptibly wider than the anterior margin of the pronotum; eyes 

 \ cry large and prominent, considerablj longer than the anterior 

 margin of tin- cheeks below them, separated above by the narrow ver- 

 tex, which is no witler than the diameter of the basal antenna! joint; 

 fastigium of the vertex horizontal, slightly transverse, with its anterior 

 margin provided with a raised border, which separates it from the 

 tipper extremity of the very wide frontal costa; this latter fully three 

 times the width of the vertex between the eyes, plane, save for a few 

 coarse punctures and a very gentle sulcation just above the ocellus, 

 tin -ides parallel to the ocellus, where they suddenly approach and 

 continue down the face, giving off laterally a short spur midway 

 bet wein the point of narrowing and the clypeus and producing a 

 cross-like effect in the face. Lateral or facial carinas very gently 

 bowed outward, their upper and lower extremities about equidistant. 

 Front rather strongly and profusely punctulate, viewed in profile 

 straight and only gently oblique. Antennae with the basal joint 

 rather large, the remaining joints very slender, about one-third longer 

 than the combined length of the head and pronotum. The latter rather 

 strongly and closely punctured, selliform, the median carina weak, ap- 

 parent only on the hind lobe, all three of the transverse sulci continu- 

 ous, the last most profound, situated very slightly back of the middle; 

 anterior margin very gently and roundly emarginate at middle, the 

 hind edge evenly rounded. Hind femora somewhat robust, evenly 

 tapering towards the apex, the pinnae of outer face quite regular, the 

 genicular lobes acuminate. Hind tibiae plainly shorter than the 

 femora, a little expanded at apex, the external row of spines composed 

 of seven in number; hind tarsi remarkably long and slender, the 

 second joint cylindrical, slightly longer than either the first or third. 

 Mesosternal lobes separated by a space about equal in width to the 

 lobes themselves, the latter with their inner edge rounded. Pro- 

 sternal spine robust, slightly transverse, the apex widely rounded; 



General color dull brunneo-cinereous with an olivaceous tinge, 

 varied on front, occiput, cheeks, pronotum, and legs by markings of 

 dull testaceous. Legs dimly fasciate; hind tibiae cinereo-plumbeous, 

 the hind tarsi carmine, striped longitudinally with black on the first
