inflated proximad, appreciably compressed, ventro-external margin 

 with six spines, ventro-internal margin with five to eight spines, 

 genicular lobes bluntly bispinose: caudal tibiae faintly longer than 

 the femora, subcompressed, particularly proximad, the dorsal mar- 

 gins sublamellate carinate, multispinose, the ventral margins less 

 thickly spined, dorsal surface moderately deplanate impressed. 



Allotype. — cf; Same data as type. [United States National 

 Museum.] 



Differing from the above description of the type in the following 

 features. Stridulating field of the tegmina with its margin oblique 

 arcuate to the apex of the stridulating vein, there rounded and 

 distad very faintly arcuate the remainder of its length; stridulating 

 vein thick, strongly depressed, in fact flattened, in the greater por- 

 tion of its length transverse, narrowing distad, the distal margin of 

 the vein with a distinct cingulate ridge. Disto-dorsal abdominal 

 segment with the sinuate-emarginate character of the margin much 

 less decided than in the female, yet appreciable: cerci strongly falcate . 

 dorso-mesad, slightly thickened proximad, elsewhere uniform in 

 thickness, the extremity not acuminate, armed with two low, very 

 blunt teeth: subgenital plate with the lateral margins regularly 

 narrowing distad, the distal extremity very narrowly arcuate- 

 emarginate, the bases of the styles developed as short projections 

 on each side of the distal emargination, these projections repre- 

 sented and continued over the plate for some distance by slightly 

 diverging rounded ridges; styles short, their length subequal to the 

 distance between their bases, simple. Caudal femora with the 

 ventro-external margin bearing fom- to five spines; ventro-internal 

 margin with four to five spines. 



General color honey yellow to clay color (doubtless discolored), 

 the distal three-fifths or all of the tegmina courge-green, the vena- 

 tion in the green sections lined with light hellebore-green, the " dead " 

 area mummy-brown. Normally exposed portion of the wings col- 

 ored similarly to the tegmina. Eyes buckthorn-brown. Limbs 

 proximad of the general color, passing on the distal section of the 

 femora and the tibiae to course- and biscay-greens, these more de- 

 cided on the caudal limbs.
