distad, apex rotundato-acuminate; costal field moderately broad, 

 anal sulci joining sutural margin about two-fifths distance from base. 

 Wings from three to five complete and two to five incomplete rami. 

 Supra-anal plate produced rotundato-trigonal, arcuato-emarginate 

 laterad, apex rounded; cerci subdepressed. subequal proximad, tapering 

 distad. 



General color varying from very pale ochraceous to tawny, lateral 

 portions of pronotum buffy or whitish, costal field and portion of 

 remainder of costal margin of tegmina translucent, slightly tinted 

 with general color. Head with more or less distinct pale yellow supra- 

 antennal spots. Disk of pronotum frequently darker than general 

 color, varying from clay color to chestnut, usually distributed over 

 the disk as paired blotches or lines on base color, very rarely sub- 

 uniformly colored. Abdomen varying from ochraceous to vandyke 

 brown, darker caudad and laterad. Limbs ochraceous varying in shade. 



9. Size large (for genus); form elliptical, depressed; surface 

 glabrous. Head hardly visible cephalad of margin of pronotum; 

 inter-ocular space very slightly narrower than that between antennae. 

 Pronotum decidedly transverse, greatest length contained one and 

 three-fifths to one and three-fourths times in greatest width, regu- 

 larly arcuate laterad and cephalad, very slightly subtruncate dorsad 

 of head, caudal margin varying from arcuato-truncate to subtruncate, 

 lateral angle rounded; disk in section subarcuate, very slightly de- 

 flected laterad. Tegmina subquadrato-ovate, slightly longer than 

 pronotum, greatest width but slightly less than tegminal length, 

 distal margin broadly rounded; 19 costal field broad, reaching slightly 

 distad of middle of tegmen, anal sulcus reaching to about one-fourth 

 length of sutural margin from apex. Wings nearly as long as tegmina. 

 Abdomen broad, greatest width slightly exceeding that of pronotum; 

 supra-anal plate produced trigonal, apex acute, very rarely sub-fissate, 

 lateral margins arcuato-emarginate, surface considerably carinate 

 cephalo-caudad ; cerci depressed subfusiform. 



General color of head, pronotum, tegmina and limbs varying from 

 ochraceous to burnt umber, lateral portions of Pronotum more or less 

 distinctly ochraceous, costal portion of tegmina pale translucent 

 ochraceous. Abdomen seal brown, segments when extended seen 

 to be bay or maroon at bases. Face more or less distinctly maculate 

 with dark brown mesad. 



is Very rarely subtruncate or as rarely narrowly rounded.
