and strongly r^igoso-punctulate; lateral or facial carinse prominent, 

 quite strongly divergent below. Antenna' slender, filiform, about as 

 long as the hind femora, the basal joint quite robust and noticeably 

 elongate. Pronotum rather evenly and closely punctulate, selliform, 

 the anterior lobe about one-half longer than the posterior one, the 

 median carina visible in front of the first and last transverse sulci, 

 which are fairly deeply impressed; disk of hind lobe somewhat flat- 

 tened, the posterior margin rounded. Tegmina coriaceous, rather 

 profusely veined, nearly as long as the abdomen, of moderate width, 

 the apex rounded; wings as in ornatus. Hind femora of moderate 

 robustness, about as long as the abdomen, the carinae smooth, pinnae 

 of outer disk regular, the genicular portion rather large, the lateral 

 lobes rounded below and rectangulate at apex; hind tibiae and tarsi 

 rather large and robust; the former with seven spines externally and 

 eight internally, the latter with joints one and two about equal in 

 length. Valves of the ovipositor more robust than in ornatus. Pro- 

 sternal spine quadrate at base, rapidly tapering, the apex acuminate; 



"Face, pronotum, pleura and underside of meso- and meta-thorax rather closely 

 and profoundly punctulate. The head large, exserted, the fastigium horizontal, 

 flat and provided at front with a distinct median carina; eyes moderately large, 

 ellyptical, separated in the females by a space somewhat less than the width of the 

 frontal costa between the antennae. Frontal costa prominent above between the 

 antenna?, smooth, in nowise sulcate, but provided with a few small punctures at 

 its sides near the upper extremity, below the ocellus narrowed, gently sulcate and 

 fading towards the clypeus. Antennae and ocellus situated higher up on the front 

 and closer than usual to the fastigium; the former moderately heavy but filiform, 

 about 25-jointed, the apical four or five pallid as in Copiocera, Rhicnoderma and 

 several other tropical American genera; lateral carinae of the face prominent, evenly 

 and strongly divergent, extending from the outer edge of the antennal sockets to 

 near the apex of the mandibles. Pronotum with the two lobes about equal in 

 length, the anterior lobe cylindrical, the posterior one divergent, the disk of the 

 latter flat and with its hind edge obtusangulate, front edge broadly margined and 

 roundly advanced upon the occiput, in some species with the middle shallowly and 

 roundly emarginate. Tegmina surpassing the apex of abdomen, with parallel edges, 

 coriaceous, rather profusely veined basally, but more sparsely so apically, the apex 

 rounded. Hind femora rather short and fairly robust, considerably shorter than 

 the abdomen, with smooth carinae and regular pinnae on external disk, the genicular 

 lobes more or less angulate; hind tibiae plainly shorter than the femora; robust, 

 seven- or eight-spined on outer edge, the apical one wanting; the second tarsal 

 joint about one-half the length of the first. Anterior and middle legs rather short. 

 Prosternal spine somewhat robust, directed gently to the rear, its apex blunt. 

 Interspace between the mesosternal lobes transverse. Valves of the ovipositor 

 normal. Body and legs somewhat hirsute."
