MORGAN HEBARD 351 



sulcate. Antennae elongate, as long as the caudal femur. Eye 

 prominent, very slightly longer than cheek. Pronotum with 

 medio-longitudinal carina distinct on metanotum (elsewhere 

 obsolete in type, very feeble in occasional individuals), caudal 

 margin of disk very weakly rounded obtuse-angulate produced. 

 Tegmina ample, overlapping, definitely longer than pronotum, 

 apices broadly rounded, dorsal and lateral fields weakly defined 

 but distinguishable. Prosternal spine small, blunt conical. 

 Furcula represented by two small blunt projections. Supra-anal 

 plate distinctly longer than broad, triangularly shield-shaped, a 

 pair of heavy medio-longitudinal carinae present proximad, 

 followed by the distal slightly raised area, the lateral margins of 

 which are formed by much weaker and more rounded short longi- 

 tudinal carinae, often with a short longitudinal carina inside the 

 lateral margins opposite the cereal bases. Cercus almost two 

 and one-fifth times as long as proximal width, curving gently 

 inward, tapering strongly in proximal half due to the declivity 

 and slight concavity of the dorsal margin; shaft mesad slender, 

 less than half as wide as proximad; slightly over distal third 

 enlarged, moderately flattened, its dorsal margin convex pro- 

 duced, the disto- ventral angle produced in a minute acute tooth; 

 ventral margin of cercus nearly straight. Subgenital plate small, 

 apex rounded (often slightly elevated, rarely definitely forming a 

 low blunt tubercle). 



Allotype. — 9 ; same data as type. [Hebard Collection]. 



Much larger and more robust than male with eyes less prom- 

 inent. Sulcation of vertex and frontal costa much weaker than 

 in that sex. Amplitude of tegmina (usually) even more con- 

 spicuous than in male. Prosternal spine shorter and heavier. 

 Ovipositor valves moderately elongate, curvature at apices 

 moderate. 



Coloration generally brown, a broad shining blackish postocular 

 band extending to abdomen. Ventral portions of pronotal 

 lateral lobes brownish buff, ventral portions of face slightly darker. 

 Cephalic and median limbs light brownish, in life possibly always 

 yellow green, this richer in males than in females. Caudal femora 

 with characteristic dark markings of group often diffused and 

 extensive, never intensive, but often running together ventrad in 

 males; these markings weaker, often obsolete in dried females. 

 The male subgenital plate is blackish except for the narrow sub- 

 chitinous proximal buffy area, the preceding sternite blackish 

 except for a very large transverse rectangular buffy area.
