first antennal joint, separated a brief distance from the weakly 

 bituberculate facial fastigium. Eyes broad oval, more prominent 

 than in Mecopoda elongata (Linnaeus). Pronotal disk flattened, 

 showing very weak concavity, its surface rugulose, with two distinct 

 transverse sutures, which laterad form decided V-emarginations 

 of the lateral margins; cephalic margin weakly emarginate, with 

 median section transverse (or subconvex) ; caudal margin subtrun- 

 cate, showing very weak subangular convexity, with a minute but 

 conspicuous, erect tubercle mesad; lateral margins moderately 

 divergent caudad and subconvex, coarsely and equally tuberculate, 

 this slightly rregular in mesozonal section. Lateral lobes of pro- 

 notum longer than deep; ventral margin horizontal, except in 

 caudal portion, where it is moderately oblique, ventro-cephalic 

 angle subdenticulate, a thoracic plate with below a small rounded 

 denticulation. Tegmina and wings showing slight reduction, not 

 extending beyond apices of caudal femora. Tegmina broadening 

 to meso-distal point, then narrowing to the apex, which is median 

 in position and rounded, the convexity of the sutural margin to the 

 apex less than that of the costal margin, the former being in this 

 portion subundulate. Tegminal venation somewhat irregular, 

 first branch of median vein near end of proximal three-fifths, this 

 branch forking at extremity of largest areola (in which is contained 

 the desiccated spot), a second branch distad, which again forks 

 distad. Ovipositor moderately elongate, evenly and weakly 

 curved upward, of the same general type as in Mecopoda elongata 

 but heavier. Subgenital plate convex, rounded triangular, with 

 apex weakly angulate-emarginate. Cephalic and median femora 

 roughened, with minute tubercles. Caudal femora armed dorsad 

 and ventrad with long, heavy spines. Cephalic tibiae with apert 

 auditory foramina, as described above, dorsal surface weakly sul- 

 cate, with lateral margins spined. 



General coloration ochraceous-tawny, often with a more buffy 

 tinge. Antennae darker, with short, widely spaced, buffy annuli 

 distad. Lateral lobes of pronotum and tegmina toward lateral 

 margins of anal field often somewhat darker. Tegmina moderately 

 glossy, with small suffusions of dark brown along distal portion of 

 sutural margin at apices of veins and with one large patch (and 

 sometimes one or two smaller patches in adjacent areolae), which 

 appears desiccated, meso-distad in median portion of largest areola 

 of discoidal field. 



Measurements (in millimeters) 



Three paratypes, bearing the same data as the type, are at hand.
