Others; middle tibiae similar in ventral armature to the anterior 

 ones but the spines less nearly opposite each other, above armed 

 on the caudal margin only with four very small but distinct tri- 

 angular teeth ; posterior tibiae armed above and beneath on both 

 margins with black based spines, an apical one above on the 

 caudal margin only; all femora unarmed above, the genicula- 

 tions rounded except the caudal ones of the intermediate and 

 posterior legs which are spined; anterior and intermediate 

 femora armed beneath on the cephalic margin only with four 

 short triangular spines ; posterior femora strongly swollen in 

 the basal two-thirds and armed beneath on the outer carina 

 with five or six stout spines, those toward the apex the longer 

 and somewhat curved. Organs of flight fully developed, the 

 tegmina moderately slender and more than four times as long 

 as the pronotum, considerably tapered in the apical half, the tip 

 somewhat narrowly rounded ; radial veins separated for most 

 of their length by a distance equal to about twice the width of 

 one of them ; tympani small, that of the right tegmen trans- 

 parent, that of the opposite one coriaceous, the stridulating 

 vein not at all projecting beyond the inner margin ; wings of 

 about equal length with that of the tegmina and about as broad 

 as long, very slightly fuliginous. Last abdominal segment 

 apically very deeply and broadly incised, the margin fringed 

 with fine long hairs ; supraanal plate partly concealed but ap- 

 parently broadly rounded apically ; subgenital plate moderately 

 elongate, triangularly notched apically and furnished with a 

 pair of cylindrical slightly clavate and apically broadly rounded 

 styles about four times as long as broad and, like most of the 

 apical portion of the whole abdomen, covered with short pile ; 

 cerci cylindrical, short, scarcely four times as long as broad, 

 apically moderately incurved and armed with a subapical 

 chitinized tooth on the inner side. 



General color yellowish brown ; head infuscated on the occi- 

 put and the pronotum blackish on the metanotal shoulders from 

 the posterior transverse furrow backward and across the full 

 width of the posterior edge of the pronotal disk, the anterior 

 margin of which is also narrowly blackish ; spines of the legs 

 piceous with the apices tinged with reddish, those of the an-
