triangular projection: styles nearly reaching the tips of the caudate 

 wings. Cephalic femora subequal to the length of the head and pro- 

 notum combined, straight, tapering; cephalic tibiae faintly shorter 

 than the femora, strongly inflated in the proximal half, subequal 

 and moderately slender distad, tympanum of the cephalic face large, 

 elongate elliptical, of the caudal face smaller, subelliptical. Caudal 

 femora faintly shorter than the tegmina, moderately robust proximad, 

 tapering distad: caudal tibise subequal to the femora in length, the 

 marginal spines placed as in the other species here described, disto- 

 external spurs very small, the dorsal one minute, disto-internal spurs 

 two in number, the dorsal one half as long as the metatarsus, the ven- 

 tral one two-thirds as long as the dorsal one : caudal metatarsi with 

 its length contained about three and one-half times in the length of 

 the caudal tibiae, the dorsal margins each armed distad with a single 

 tooth, distal spur of the internal face reaching to about the middle of 

 the third tarsal joint, the external spur hardly surpassing the middle 

 of the second joint. 

 ' Allotype : 9 ; same date as the type. 



Differing from the description of the type in the following features. 

 Pronotum relatively heavier than in the male, broader in proportion 

 to the width of the head, the caudal margin of the disk weakly pro- 

 duced mesad, rounded, very faintly sinuate laterad of the median 

 production: lateral lobes with the cephalic margin more oblique 

 truncate, the ventro-cephalic angle rounded obtuse. Tegmina nar- 

 row, elongate, slightly surpassing the apex of the abdomen (exclusive 

 of the ovipositor), when in repose the lateral margins of the tegmina 

 are subparallel, narrowing at the distal extremity to the narrowly 

 rounded apex: lateral field with the veins more regularly disposed 

 than in the male, straighter, and more distinctly diverging: dorsal 

 field with the anal and axillary (two) veins moderately sinuate, trans- 

 verse nervures numerous and irregularly distributed. Ovipositor in 

 length subequal to that of the head and pronotum combined, mod- 

 erately falcate, of medium depth, distal extremity of the dorsal mar- 

 gin and the vicinity of the valvular suture in the distal third with fine 

 strumose denticulations, apex acute. 



General color antimony yellow, becoming warm buff on the tegmina, 

 the abdomen with a tendency toward ochraceous-buff, ovipositor 

 tipped with mars brown, the eyes varying from the general color to 

 dresden brown.
