equal to the length of the head and pronotuiii, thick, slightly depressed 

 and subensiforni proxirnad, apex blunt. Pronotum very slightly 

 more than two-fifths the length of the caudal femur, dorsum nearly 

 plane; cephalic margin arcuato-truncate, \\dth a distinct but slight 

 median emargination, caudal margin broadly obtuse-angulate, the 

 immediate angle truncate and the entire margin crenulato-sinuate ; 

 median carina very low, weak on the prozona, lateral angles rounded, 

 a shoulder present on the metazona; lateral lobes decidedly longer 

 than deep, ventral margin sinuato-emarginate cephalatl, median and 

 ventro-caudal angles obtuse; transverse sulci three in number, the 

 caudal deeper than the others, the prozona about three-fifths the 

 length of the pronotum. Tegmina coriaceous, reaching about to the 

 middle of the abdomen, lanceolate, the greatest width 

 contained about three times in the length, costal lobe 

 rather long but low. Wings slightly shorter than the 

 tegmina. Prosternal spine erect, conic, slightly blunted 

 at the apex; interspace between the mesosternal lobes 

 subquadrate, slightly narrower than the width of one of 

 the lobes; interspace between the metasternal lobes sub- 

 trigonal, the distance separating the lobes being about half 

 the length of the interspace. Abdomen moderately com- 

 pressed, carinate dorsad; ovipositor jaws rather long, 

 shallowly dentato-crenulate. Cephalic and median limbs 

 of medium build. Cauaal femora slightly less than one 

 and one-half times the length of the head and pronotum 

 together, moderately robust, the greatest width contained 

 slightly more than three times in the length, pagina with 

 a moderately regular but not very close pattern, dorsal 

 carina entire, genicular lobes acute with the immediate 

 apex well rounded ; caudal tibiae slightly shorter than the 

 femora, slightly sinuate, armed on the external margin 

 with six to seven spines, on the internal margin with nine 

 spines, no apical spine present on the external margin. 



General color Vandyke brown, a broad dorsal bar extending from 

 the fastigium over the occiput, whole of the dorsum of the pronotum 

 and all of anal areas of the tegmina ochraceous in color, clouded 

 on the occiput and ]:»ronotum with Vandyke brown. An irregular 

 infra-antennal transverse bar and a broad bar covering the genae, 

 ventral portion of the lateral lobes and touching the pleura dull 

 raw sienna. Abdomen raw umber. Eyes raw umber; antennae 

 dull gallstone yellow, becoming tawny proximad. Caudal femora 

 with the external face clouded with blackish, the ventral portion of
