262 PROCEEDINGS OF THE ACADEMY OF [May-Qct., 



ventro-cephalic angle rounded obtuse, ventral margin oblique sub- 

 truncate, ventro-caudal angle and caudal margin broadly and regu- 

 larly arcuate, humeral sinus moderately decided, rounded rectangu- 

 late. 



Tegmina about half again as long as the body, lanceolate, the 

 greatest width contained slightly more than three and two-thirds 

 times in the length of the same, the marginal field at the proximal 

 third of the tegmen forming two-fifths of the entire tegminal width: 

 costal margin well arcuate proximad and distad, flattened mesad, 

 apex moderately narrowed but well rounded, sutural margin gently 

 arcuate: marginal field with numerous but coarse areolations, which 

 are deeply etched, among which there stands out above seven poorly 

 defined ol^lique rami of the humeral vein; median vein diverging 

 slightly distad of the middle of the tegmen, this bifurcate with the 

 rami reaching the sutural margin shortly proximad of the apex, 

 these and the ulnar vein much fractured and in consequence some- 

 what zig-zag in their direction, the areolations of the discoidal field 

 in general, but particularly proximad, finer than those of the mar- 

 ginal field: stridulating field relatively small, the margin rounded 

 obtuse-angulate at the apex of the stridulating vein, the latter 

 slightly oblique, gently arcuate, distinctly depressed, thickened. 

 Wings with the normally exposed portion projecting distad of the 

 tegmina a distance equal to the length of the pronotal disk, the 

 form of the apex narrowly rounded acute. 



Prosternum with a broadly V-shaped carinate elevation: meso- 

 sternal lobes very small, rounded rectangulate, convergent: meta- 

 sternal lobes similar to the mesosternal lobes but slightly larger. 

 Disto-dorsal abdominal segment .moderately cucullate, the mar- 

 gin arcuate-emarginate laterad around the cereal bases, the distal 

 margin proper (mesad) shallowly arcuate-emarginate: cerci with 

 the main (ventral) shaft about two-thirds as long as the disk of 

 the pronotum, weakly compressed, gently falciform, tapering in 

 proximal half, subequal in distal half where the width is little more 

 than half that at the base, the apex with an unguiculate spine; 

 dorsal articulate section of the cercus about half again as long as 

 the ventral portion, straight, at the middle on the ventral surface 

 there is developed a low but distinct lamellation, which is regu- 

 larly arcuate proximad, oblique subtruncate distad, the angle nar- 

 rowly rounded, the general form of this lamellation strongly sug- 

 gesting the femoral lobes of certain mantids of the subfamilies 

 Vatinae and Empusinae, the distal section of this arm of the cercus
