facial shield strongly transverse, tlie general form arcuato dorsad, 

 dorsal margin narrowly subtruncate mesad, arcuato-cmarginate 

 laterad of the same, ventral margin moderately arcuato-emarginate; 

 eyes prominent, rounded, when viewed from the side seem to be 

 P3n'iform-ovate; antennae missing. Pronotum with the greatest 

 (supra-coxal) \vidth contained nearly five times in the length of the 

 same, shaft two and one-half times the length of the collar; cephalic 

 extremity well rounded, margins of collar gradually tapering from 

 shortly cephalad of the supra-coxal msertion to the distal extremity; 

 supra-coxal lobes but little expanded, rounded; shaft subequal in 

 width for a distance caudad of the supracoxal lobes, thence slightly 

 expanding caudad to the caudal margin, which is 

 truncate mesad and obliquely arcuato-truncate lat- 

 erad; median carina present on the whole shaft and 

 the greater portion of the collar, placed for the greater 

 part of its length in a narrow sulciform depression; 

 surface of shaft sparsely but regularly tuberculate, 

 surface of collar subdeplanate mesad, a deeply im- 

 pressed ovate figure failing to reach the much shal- 

 lower transverse sulcus, this figure strongly outlined 

 with marginal carinse laterad and flanked mesad with 

 three to four distinct tubercles on each side and 

 some scattered smaller median ones ; lateral margins 

 of the whole pronotum dentato-spinose, the spines of 

 greatest length on the median portion of the shaft. 

 Tegmina and wings over twice the length of the pro- 

 notum; marginal field of the former moderately wide 

 proximad, gradually narro^ving distad. Abdomen 

 with the apex missing. Cephalic coxae two-tliirds the 

 length of the pronotum; ventral surface sparsely tu- 

 berculate, ventro-internal margin serrato-denticulate; 

 external margin serrulate; dorsal margin with the 

 distal lamellation forming about one-tliird of the en- 

 tire length, the margin of the same with eight to nine 

 decided denticulations, the dorsal margm proximad of the lamella- 

 tion arcuato-emarginate, proximal portion of the same margin ser- 

 rato-denticulate: cephalic femora sHghtly exceeding the pronotal 

 shaft in length, very slender, dorsal margin nearly straight with, a 

 blunt subtrigonal depressed supra-genicular projection; ventro- 

 external margin armed with five spines, one very small and genicu- 

 lar in position; ventro-internal margin armed vni\\ fourteen spines 

 placed in the foDowing fashion (reading from the distal extremity) 

 iTiiIiIiIiIiIi, the distal one small, genicular and weU separated from 

 the others; discoidal spines four in number: cephalic tibiie (exclusive
