52 TETTIGID.E OF NORTH AMERICA 



PLATYTHORUS CAMURUS, MORSE. 



Plate I., Fig. 3. 



Body much depressed, granulate; eyes of moderate size. 

 Vertex horizontal, one and one-third times as wide as one of 

 the eyes, squarely truncate, with small but distinct mid-carina, 

 the transverse carinre separated from it by a shallow groove, 

 but continued into low ridge running backward along each 

 side of the mid-carina. Antennze elongate, distinctly passing 

 the shoulders, filiform, joints 7-10 the longest, the basal joint 

 two-thirds the width of one of the eyes in length, inserted in 

 a line with the lower margin of the eyes. Facial costa low 

 above, forking midway between the ocelli and vertex into 

 high, narrowly divergent rami, which form in profile a strong 

 protuberance opposite the points of insertion of the antennae. 

 Pronotum strongly depressed, granulate, flat above, truncate 

 in front, cuneate behind, with pinched almost mucronate apex; 

 mid-carina distinct in front of and behind the shoulders, nearly 

 obsolete elsewhere, in profile undulate; lateral lobes laminately 

 produced, obliquel}' truncate at the ajjex, angles obtuse, 

 rounded. Elytra and wings absent, anterior and middle femora 

 strongly carinate, with sinuato-lobate margins. Hind femora 

 partaking of the general depressed form of the body, but very 

 stout from side to side; femoral lobes small, genicular lobes 

 prominent, acutely pointed. 



Total length, j, g.6 mm.; pronotum, 8.5 mm.; post, fem., 

 6.3 mm.; antennre, 5.5-6 mm. (estimated). 



Habitat, Nicaragua, Chontales (Janson).
