transverse. Subgenital plate simple, truncate meso-distad, reaching scarcely 

 beyond cereal bases, margin slightly concave beneath cereal bases. Limbs, arma- 

 ment and other features given in generic description.

Size small, form moderately broad. Eyes large, subattingent. Maxillary palpi 

 with fourth and fifth joints subequal in length, each slightly shorter than third. 

 Antennae much more elongate than in female, but with joints very similar except 

 that the distal joints grade to three times as long as wide. Caudal margin of 

 pronotum showing weak convexities on each side above the humeral trunk of the 

 tegmina. Tegmina extending beyond apex of abdomen a distance equal to the 

 tegminal width; marginal field occupied by an irregular network of very fine vein- 

 lets; discoidal field with (eight) moderately radiating discoidal sectors; anal sulcus 

 curving sharply distad toward sutural margin. Wings with (six) incomplete and 

 (three) complete branches of the ulnar vein. 



Dorsal surface of the abdomen with third, fourth and fifth segments each showing 

 along delicate transverse ridge proximad ; latero-caudal angles of segments not pro- 

 duced, rectangulate, with apices rather broadly rounded, except those of seventh 

 segment which are weakly produced, subrectangulate with apex rather sharply 

 rounded, eighth segment concealed. Supra-anal plate exceedingly delicate, pro- 

 duced, nearly twice as broad as long; caudal margin almost transverse, very feebly 

 convex; latero-caudal angles very broadly rounded. Cerci short, delicate, not 

 extending as far as caudal margin of supra-anal plate. Subgenital plate roundly 

 produced sinistrad a distance slightly over half that of supra-anal plate, forming 

 dextrad a large and weakly obtuse-angulate emargination, from the apex of which 

 springs a slender, straight style, three-quarters as long as the adjacent cercus, with 

 apex furnished with a few minute hairs.

Pronotum transparent, .hyaline with a faint buffy tinge, except for the meso- 

 caudal area, which, in a rather broad, inverted V-shaped space with lateral margins 

 concave, is russet, showing microscopic scattered flecks of buff. Tegmina and
