Head large, as long as, and a little wider than, the anterior edge of 

 the pronotum, the occiput a very little ascending above the level of 

 the former, the face viewed in profile rather strongly oblique; eyes 

 large and fairly prominent, oval, plainly longer than the anterior edge 

 of the cheeks immediately beneath them, separated on the vertex by 

 a space a trifle greater (cf ) or fully one and one-half times the diameter 

 of the basal antennal joint (9), the fastigium horizontal, about as 

 long as wide in the male or plainly wider then long in the female, 

 deeply sulcate in the former in the form of the bowl of a spoon, in the 

 latter with a lunate sulcation immediately back of the front end, 

 antero-lateral carinae meeting at front in an acute angle (cf ) or forming 

 a very slightly obtuse angle (9), lateral foveolse scarcely apparent. 

 Frontal costa narrowed above and roundly uniting with the fastigium, 

 plane above the ocellus, gradually widening, and continuous to the 

 clypeus, very gently sulcate at the ocellus; lateral or facial carinae 

 prominent, rather strongly divergent below. Antenna? graceful, 

 filiform, about equal to (9) or a third longer (cf) than the hind 

 femora. Pronotum a little longer than high, its sides about parallel, 

 the disk of the hind lobe flattened, rather profusely punctulate; the 

 lateral carinae sharp and prominent, convergent to the principal sulcus, 

 interrupted till the immediate anterior edge of the front lobe, where 

 they appear as oblique dashes; median carina slender, but plainly 

 visible throughout; hind margin subangulate. Tegmina narrow, their 

 apex rounded, fully as long ( 9 ) or plainly surpassing the tip of the 

 abdomen (cf ), the dorsal field closely, but not prominently, veined, 

 the discal area without an intercalary vein. Hind femora long, rather 

 robust on basal half, but slender on apical half, extending beyond the 

 apex of the abdomen by one-fourth ( 9 ) or fully two-fifths of their 

 length (cf). Hind tibiae provided with eleven spines in the outer 

 row . Valves of the ovipositor short and robust; last ventral segment 

 of the male abdomen short and roundly acuminate, the cerci moder- 

 ately robust, straight, evenly tapering, and, like the tibiae and tarsi, 

 lengthily hirsute. Interspace between the mesosternal lobes slightly 

 transverse in both sexes. 



Sides of head back of eyes, upper half of lateral lobes of pronotum, 

 upper edges of pleura and costal and discal fields of tegmina, black, 

 duller in the females; dorsal portion of tegmina grass-green, anterior 

 and middle legs greenish-olive, duller in females; fastigium, vertex, 

 and middle of occiput, together with the disk of pronotum, longi-
