broad ; cerci bluntly conical, scarcely longer than broad, each 

 about as broad as the subgenital plate and simple. Legs very 

 short, the fore femora shorter than the pronotum and the 

 posterior ones less than twice as long ; middle legs missing from 

 the unique type of the only known species ; anterior femora 

 unarmed above, beneath armed on the inner margin only with 

 two or three short stout spines on the apical half ; fore tibiae 

 flat and unarmed above, beneath armed with a few very small 

 fine spines, extremely minute on the caudal margin, those on 

 the cephalic margin larger and about five in number ; posterior 

 femora stout, but little more than twice as long as the greatest 

 width, only about the apical fifth parallel, unarmed above, be- 

 neath armed on the outer margin only with six stout triangular 

 spines, the genicular angles unarmed, as are also those of the 

 fore femora ; posterior tibiae armed above on the caudal margin 

 with eight broad-based spines, the last one near the apex, and 

 on the cephalic margin with three very small depressed apically 

 pointed tubercles on the basal half ; beneath on the apical half 

 with several very minute spinules on the cephalic margin, the 

 caudal margin with a few still more minute ones near the apex ; 

 the hind tibiae are without apical calcars above, the lateral and 

 ventral pairs short. Tegmina and wings of equal length, barely 

 reaching the tips of the posterior femora and not far surpassing 

 the tip of the abdomen ; tegmina about two and one-half times 

 as long as broad, coriaceous, thick and opaque, the radial veins 

 nearly straight, at the base far separated, gradually drawing 

 nearer toward the apex, the posterior one dividing the tegmina 

 into about equal halves ; wings equally long as broad, trans- 

 lucid, the veins yellowish ; the outer margin evenly rounded, not 

 at all sinuate.
