space finely rugulose and with regularly placed impressed pits with 

 fine, diverging radial lines: interspace between the antennal scrobes 

 very faintly narrower than that between the eyes, moderately ar- 

 cuate in section, glabrous: palpi with the fourth joint very slender 

 proximad, regularly expanding distad, the apical margin obliquel}^ 

 truncate; distal article longer than the fourth joint, broad, greatest 

 width at proximal third, margins regularly converging to the acute 

 apex: eyes with facets clearly defined and slightly elevated individu- 

 ally: antennae at least as long as the body, the proximal segment 

 short moniliform, subglobose, the joints becoming progressively 

 longitudinal distad, regularly pilose. Pronotum transversely short 

 elliptical, the greatest length contained one and one-fifth times in the 

 greatest width: all margins arcuate, the nearest approach to angula- 

 tion being the weakly suggested latero-caudal angles: oblique de- 

 pressions distinct, extending from the medio-caudal section toward 

 the usual position of the latero-cephalic angles, then turning mesad 

 and extending subparallel to the cephalic margin, vanishing caudad 

 Ijefore reaching the middle line, the enclosed area moderately bullate, 

 with irregularly placed and irregularly indicated slight transverse 

 wrinkles, no medio-longitudinal impression: lateral sections of pro- 

 notum weakly declivent. Tegmina coriaceous, haired as the other 

 portions of the body, lanceolate-elliptical, the greatest width con- 

 tained three times in the greatest length of the tegmen : costal mar- 

 gin lightly and regularly arcuate; sutural margin straight for the 

 greater portion of the pmximal two-thirds, arcuate distad; apex 

 rather broadly rounded; the entire costal margin thickened and finely 

 nodulose cingulate: marginal field occupying about the proximal 

 two-fifths, well developed, moderately wide: six well defined costal 

 veins indicated: discoidal field with six definite longitudinal sectors 

 (including the discoidal vein itself), these sinuate, connected by cross- 

 veins and forming quadrate to oblong interspaces, all obsolete distad, 

 becoming lost in the coriaceous shagreenous condition of that region ; 

 anal sulcus distinct, impressed, arcuate proximad, straight oblique 

 distad, joining the sutural margin near the proximal third; anal field 

 elongate pyriform; axillary veins three in number, poorly defined. 

 Wings faintly surpassing the tegminal apices when all are in repose. 

 Supra-anal plate transverse, the free margin sinuate-arcuate: cerci 

 moderately long, robust, subfusiform, the apex rather short acute, 

 the whole subdepressed : subgenital plate asymmetrical, from the- 

 sinistral side the margin is developed as follows: obliquely arcuate- 

 emarginate ventrad of the cercus, then developed into an acute, peg-
