sulci decided. Tegmina elongate-lanceolate, greatest width at about 

 third of length from apex, length four to four and one-half times that 

 of pronotum, greatest width contained two and two-thirds to three 

 times in length; costal margin arcuate proximad and distad, apex 

 rounded; anal sulcus reaching sutural margin slightly distad of one- 

 third length of same. Wings with two to five complete and two to 

 four incomplete ulnar rami. Supra-anal plate decidedly transverse, 

 margin hardly produced, arcuate; cerci terete. 



General color pale ochraceous, pronotum and costal field of teg- 

 mina translucent, disk of former rarely clouded with splotches of 

 brownish; eyes hair brown; abdomen washed distad with dilute 

 prout's brown. 



9. Size small; form elliptical, depressed; surface glabrous. Head 



hardly visible cephalad of pronotum; interspace between eyes slightly 



greater than that between antennal bases; antennae about equal to 



body in length. Pronotum semi-ovate, greatest length contained 



about one and one-half times in greatest width, lateral and cephalic 



margins strongly arcuate, slightly subtruncate dorsad of head, caudal 



margin arcuato-truncate, lateral angles caudad of middle and narrowly 



rounded obtuse-angulate ; disk slightly arcuate in transverse section. 



distinctly declivent laterad, oblique sulci not or but slightly indicated, 



Tegmina subquadrate, hardly longer than 



pronotum, attingent but hardly overlapping; VZ^ ^"\i^ ' 



costal margin moderately arcuate, distal margin

obliquely sinuato-truncate, apex costal and well noptera bore a lis 



rounded; anal sulcus reaching to disto-sutural Brunner Supra-anal 

 angle, which latter is very broadly rounded. <£(x°5). Male; Boy- 

 Wings minute. Supra-anal plate sub-trigonal, kins, Va.: female; 

 angle obtuse, lateral margins slightly concavo- 



emarginate, immediate apex narrowly rounded; cerci depressed, 

 rather broad mesad, subfusiform. 



General color tawny becoming seal brown caudad, latter color cover- 

 ing dorsum and frequently venter of abdomen, rarely seal brown 

 is uniform color of dorsum. Head often with face seal brown, more 

 rarely tawny. Pronotum occasionally with disk darker than general 

 color, thus forming a broad lateral pale margin on pronotum and 

 sometimes on costal field of tegmina.
