length, over twice the length of the head and pronotum together; 

 greatest widtli in the apical fourth ; costal expansion distinct, 

 one-fourth the distance from the base, remainder of costal margin 

 straight except near the apex where it is rounded; apex obliquely 

 truncate, subrectangulate ventrad, obtuse-angulate dorsad ; anal margin 

 straight. Wings equal to the tegmina in length. Prosternal spine erect, 

 acute, distinctly compressed . Interspace between the mesosternal lobes 

 quadrate, slightly less than the width of one of the lobes, the lobes 

 rounded. Interspace between the metasternal lobes longitudinal, 

 about one and a half times as long as the caudal interspace, cephalic 

 width slightly greater, lobes rounded. Abdomen strongly com- 

 pressed, carinate dorsad. Cephalic femora straight, the greatest 

 width in the distal third, length nearly three-fourths that of the 

 pronotum, genicular lobes rounded, the cephalic much larger than 

 the caudal; tibiae as long as the femora, the spines on distal portion 

 strong; tarsi but little shorter than the tibiae, the median joint little 

 more than a third the length of the proximal, the distal joint slightly 

 exceeding the proximal and median in length, arolia present. Median 

 femora about equal in length to the cephalic but more compressed, 

 genicular lobes, tibiae and tarsi as in the cephalic limbs. Caudal femora 

 elongate, slender, two-thirds the length of the tegmina, proximal por- 

 tion considerably inflated, the greatest width contained four and a half 

 times in the length of the femur, dorsal carinse serrate, pattern of the 

 pagina elevated, distinct and regular, areas on the dorsal face finely 

 tuberculate, ventral areas glabrous, pregenicular region distinctly 

 constricted and extending a considerable distance proximad, genicular 

 region little arched and produced into a pair of subacute processes 

 dorsad, genicular lobes short, narrowly rounded at the apex; tibiae 

 slightly shorter than the femora, slightly sinuate, external margin with 

 nine spines, internal margin with eleven including the apical; tarsi 

 about one-third the length of the tibiae, the proximal and distal joints 

 subequal in length, median joint about half the length of the proximal, 

 arolia present. 



General color, broccoli brown minutely speckled with bistre. Head 

 inclined toward tawny olive, two diverging suboljsolete senrilunate 

 blotches of umber on the occiput; eyes prout's brown. Pronotum 

 with the prozona very slightly lighter than the metazona, the whole 

 uniformly dotted with bistre. Tegmina with numerous regularly dis- 

 posed quadrate blotches of dilute bistre, those of the costal and anal 

 areas smaller than the blotches of the discoidal area. Wings of the 

 same tint as the tegmina. Segments of the abdomen margined with
