carina slight and low but quite apparent on the whole dorsum; 

 lateral angles moderately rounded on the prozona, very slightly 

 rounded on the metazona, the disk very gradually widening caudad ; 

 transverse sulci three in number, distinct, narrow, metazona about 

 three-fifths of the entire length of the pronotum; lateral lobes \ery 

 considerably longer than deep, the ventral margin strongly arcuato-

emarginate cephalad, caudal section of the ventral margin straight, 

 the ventro-caudal angle very broadly rounded. Tegmina very long 

 and slender, exceeding the tips of the caudal femora by nearly the 

 length of the pronotum, subequal; apex lanceolate. Wings equal to 

 the tegmina. Prosternal spine conic, blunt, slightly retrorse; inter- 

 space between the mesosternal lobes slightly longitudinal, the inter- 

 space but little more than half the width of one of the 

 lobes, the internal margin of the lobes convex arcuate; | I 



metasternal lobes contiguous. Abdomen slightly com- \ /; 



pressed; supra-anal plate lanceolate, the margin notched \ J! 



distad of the middle for the reception of the cerci, disk \ jj 

 considerably depressed ; cerci robust and tapering in the 

 proximal half, thence sharply bent dorsad and narrowed 

 to about a third the proximal width, tapering to the 

 rather blunt apex, the axis of the cercus from the median 

 bend being slightly toward the median line of the body, 

 then curved slightly laterad at the tip; subgenital plate 

 moderately compressed, the dorsal margins acute-angu- 

 late but not reaching to the inflated, sub-bulbous apex, 

 the latter being moderately rounded when seen from 

 the side. Cephalic and median limbs rather slender. 

 Caudal femora surpassing the apex of the abdomen, 

 the length being two and one-half times that of the 

 somewhat compressed, proximal portion regularly and evenly, but 

 not greatly, inflated, tapering to the genicular region, genicular 

 lobes moderately acute-angulate, pagina regularly and in the proximal 

 section very closely patterned; caudal tibiae distinctly shorter than 

 the femora, the distal portion considerably inflated, the margins
