siderably so in the male; cephalic margin obtuse-angulate, slightly 

 more marked in the male than in the female; caudal angle aciite- 

 angulate, the apex sharp and the margins slightly arcuato-emarginate ; 

 lateral shoulders marked on the metazona, a continuation descending 

 obliquely ventro-cephalad on the prozonal portion of the lateral lobes 

 prozona of the disk with accessory lateral shoulders, which are less 

 marked than the primary ones, converging from the principal trans- 

 verse sulcus to the cephalic margin, all the lateral shoulders more 

 marked in the male than in the female ; transverse sulci three in number, 

 all cutting the median ridge, but only the caudal one doing so deeply; 

 greatest median width of the pronotal disk contained about twice 

 in the length; lateral lobes of the pronotum with the ventral margin 

 obtuse-angulate. Tegmina of the male exceeding the length of the 

 pronotum by about half the length of the head, of the female about 

 equal to the length of the metazona and half of the prozona ; shape of 

 the male tegmina sublanceolate, of the female tegmina sub-rhomboid, 

 the greatest width of the male tegmina contained two and a half 

 times in their length, that of the female tegmina contained once and 

 two-thirds in their length. Wings much smaller than the tegmina, 

 not functional in either sex. Prosternal spine erect, conical; inter- 

 space between the mesosternal lobes very slightly transverse, the 

 angles of the lobes broadly rounded; interspace between the meta- 

 sternal lobes distinctly arcuate transverse. Abdomen compressed 

 in both sexes, distinctly carinate dorsad in the male; supra-anal 

 plate of the male acute- angulate, distinctly sulcate mesad, the sulcus 

 narrowed meso-caudad ; cerci of the male very small, simple, styliform ; 

 subgenital plate compressed, produced, rostrate, the apex elevated and 

 slender. Cephalic and median Hmbs moderately robust in the male, 

 rather weak in the female. Caudal femora about one and one-third 

 (9) or one and two-thirds (d^) the length of the pronotum, rather 

 slender, tapering, no appreciable pregenicular constriction, dorso- 

 median carina sparsely serrato-dentate, pattern of the pagina rather 

 irregular and not deeply impressed; caudal tibiae about equal to the 

 femora in length, armed on the external margin with ten to twelve 

 spines, on the internal with nine to ten spines, those of the internal 

 margin longer than those on the external; tarsi distinctly depressed. 



General color olive-green becoming brownish on some areas and 

 brighter green on others, d^. Face dull oil green, gense and occiput 

 of the general color aside from a dull broad subequal medio-longitudinal 

 bar of russet on the vertex and occiput, bordered laterad by poorly 

 defined blackish areas; eyes burnt umber. Pronotum veiy dull olive-
