Size medium; form as in other species of the genus but shghtly 

 broader. Head considerably exserted, the eyes rather prominent, 

 the interspace between them not as wide as the depth of the eye in 

 either sex; antennae fihform, very sparsely haired, in length very con- 

 siderably exceeding the length of the body. Pronotum transverse 

 sub-elliptical, cephalic margin with an extremely slight median angu- 

 lation; caudal margin distinctly but not greatly angulate, the margin 

 laterad of the angulation slightly emarginate; lateral margins arcuate 

 producing slightly lateral cephalic and caudal angles; surface of the 

 disk with two impressed areas, one or each side, extending caudo- 

 laterad from about the caudal fourth of the pronotum ; lateral portion 

 of the pronotum considerably depressed. Tegmina with the venation 

 prominent ; costal margin arcuate on the proximal half, about straight 

 with a hardly perceptible emargination in the distal half, sutural 

 margin with two arcuations, one of the anal field, the other of the 

 remainder of the tegmen; apex narrowly rounded; basal field narrow, 

 limited to about the proximal third; anal field elongate-obovate, the 

 anal sulcus more impressed in the male than in the female; costal 

 veins thirteen to sixteen in number, rami of the median vein all longi- 

 tudinal. Supra-anal plate of the male shorter than the subgenital 

 plate, cerci over twice the length of the subgenital plate, moniliform, 

 tapering from the middle, subgenital plate rather short, transverse, the 

 apex narrow and shallowly emarginate. Supra-anal plate of the 

 female shorter than the subgenital plate, cerci similar to those of the 

 male, subgenital plate flat, the apical margin with a deep, very narrow 

 median incision. Femora spined. 



General colors clove brown and pale ochre yellow. Head with three 

 median, longitudinal, closely placed, parallel ochre yellow lines on the 

 interocular space, the face with five transverse maculations of the 

 same color, the dorsal one a complete fine line, the second, between 

 the antennae, a broadly V-shaped mark, the third a row of four sub- 

 circular maculations, the fourth, on the clypeal suture, a thick, nar- 

 rowed mesad line, the fifth a simple line across the clypeus ; eyes walnut 

 brown ; antennae strongly inf uscate except a brief ferruginous proximad 

 section. Pronotum with the disk clove brown, a narrow median line 

 and the lateral section pale ochre yellow, a spot on the caudal section 

 of the pale lateral sections clove brown; caudal margin narrowdy pale. 

 Tegmina with the base color deep brownish, the basal field and inter- 

 spaces between the veins of the anal area and between the costal veins 

 and two spots in the proximal section of the discoidal field, one in the 

 very narrow proximal section and the other just distad of it, pale
