^•ith a distinct medio-longitudinal sulrus, the latter becoming obsolete proxi- 

 mad, the margins somewhat inflated; lateral ocelli large, occupying the lateral 

 faces of the broader proximal section of the fastigium, when seen from the side 

 the apex of the fastigium of the vertex is acuminate, falling slightly short of 

 the apex of the fastigium of the face, not touching the same; fastigium of the 

 face acute, apex very narrowly rounded; median ocellus subelliptical: face 

 moderately inflated transversely when seen from the dorsum, but weakly ar- 

 cuate when seen in profile; infra-ocular impression elongate, well indicated: 

 eyes but little prominent when seen from the dorsum, axis of eye extending 

 from dorso-caudad to ventro-cephalad, outline of base of eye subovate, moder- 

 ately exserted cephalad; greatest length of eye (along axis) slightly greater 

 than the greatest length of the infra-ocular impression: antennae distinctly 

 surpassing the extremities of the tegmina, filiform. 



Pronotum with dorsum plane, lateral angles of same distinct, continuous, 

 nearly straight, faintly diverging caudad, lateral lobes vertical: dorsum of 

 pronotum with greatest caudal width contained one and two-fifths times in the 

 greatest length; cephalic margin of disk broadly but not decidedly arcuate- 

 emarginate; caudal margin of disk strongly and regularly arcuate; surface of 

 disk weakly ruguloso-punctulate, a delicate but distinct median carina present 

 caudad, a distinct transverse impression present briefly caudad of the middle: 

 lateral lobes slightly deeper than the greatest dorsal width; cephalic margin 

 of the lobes straight except for a short obliquity dorsad, ventro-cephalic 

 angle rounded obtuse-angulate, ventral margin oblique, arcuato-truncate, 

 ventro-caudal angle broadlj^ rounded, caudal margin moderately arcuate, some- 

 what flattened mesad, humeral sinus deep, moderately acute, bottom of sinus 

 rounded. Tegmina elongate, sublanceolate, subequal in width, greatest 

 width contained nearly five times in the greatest length, in general form faintly 

 sigmoid: costal margin regularly but gently arcuate; sutural margin faintly 

 sigmoid; distal extremity narrowly rounded: marginal field V)road, at proximal 

 fourth nearly equal to one-half the width of the entire tegmcn, coarsely and 

 openly reticulate; discoidal field similarly but more finely reticulate: median 

 vein diverging at two-fifths of the distance from the base, bifurcate slightly 

 before the middle; ulnar vein straight except for a brief arcuation where it 

 joins the sutural margin; transverse nervures regularly and strongly indicated: 

 stridulating field entirely net-reticulate proximad of the stridulating vein, 

 similar but with a more pronounced longitudinal tendency distad of the same; 

 stridulating vein strongly arcuate, slightly oblicjue, broad, flattened. Wings 

 projecting distad of the closed tegmina a distance but slightly less than the 

 length of the pronotal disk, acute: expanded wings with the greatest width of 

 one of the wings contained two and one-quarter times in the greatest length 

 of the same. Mesosternum weakly concave cephalad, mesosternal lobes sub- 

 parallel laterad, caudal margin of segment rectangulate emarginate, the lobes 

 thus acute and strongly and abruptly deflexed from the general sternal plane: 

 metasternum with cephalic margin subtruncate, latero-cephalic angles rounded 

 sul)tuberculate, loljes arcuate laterad and regularly converging, sharply and 

 abruptly deflexed.
