288 BRAZILIAN ORTHOPTERA 



subequal in width, strongly constricted dorsad at its junction with the fastig- 

 ium, shghtly expanded around the oceUus, subobsolete ventrad on the face, 

 irregularly biseriate punctate dorsad, roughly excavato-sulcate for a short 

 distance dorsad and a great distance ventrad of the ocellus; lateral facial 

 carinae well elevated, strongly diverging ventrad, sinuate: eyes moderately 

 prominent, ovoid in basal outline, slightly flattened cephalad, in length about 

 one-half again as long as the infra-ocular portion of the genae: antennae elon- 

 gate, two and one-half times as long as the dorsal length of the pronotura, 

 slightly depressed proximad, apex weakly acuminate. Pronotum subcylin- 

 drical, the greatest caudal width of the dorsum contained one and two-thirds 

 times in the dorsal length of the same, the dorsal line straight when seen from 

 the side; cephalic margin of the disk subarcuate, slightly flattened mesad, 

 caudal margin obtusely rounded: median carina low but precurrent, very 

 weak mesad and more decided on the metazona, lateral angles rather broadly 

 rounded; metazona equal to two-thirds the length of the prozona; transverse 

 sulci well indicated, deeper on the lateral lobes than on the dorsum: lateral 

 lobes with their greatest dorsal length one and one-half times as long as the 

 greatest depth of the lobes; cephalic margin of the lobes nearly vertical, trun- 

 cate, ventral margin rather shallow arcuato-emarginate cephalad, truncate 

 caudad with a bulbous thickening of the extreme caudal section of the same, 

 caudal margin weakly sinuate, subtruncate, ventro-caudal angle rounded. 

 Tegmina reaching to the apex of the abdomen, slender: costal margin dis- 

 tinctly and regularly arcuate distad to the nan-owly rounded apex, which is 

 more sutural in position. Wings reaching to the tegminal tips: greatest width 

 contained two and one-quarter times in the greatest length of the same; apex 

 of anterior field narrowly rounded. Prosternal process of the broadly trans- 

 verse type found in the genus, thick, distal margin hardly emarginate, lateral 

 angles blunt, rounded; interspace between the mesosternal lobes narrow, 

 hour-glass shaped, the narrowest point hardly more than a fourth of the length 

 of the same interspace, the internal margins of the lobes roundly obtuse-angu- 

 late; metasternal lobes subcontiguous caudad. Cerci and ovipositor valves 

 elongate, simple, the former tapering on distal portion, the latter blunt and 

 faintly bulbous at the tips, without marginal teeth. Cephalic and median 

 limbs small. Caudal femora slightly more than half the length of the tegmina, 

 pattern of the paginae regular and well impressed: caudal tibiae about four- 

 fifths as long as caudal femora, armed on the external margin with seven to 

 eight spines,^- internal margin with nine to ten spines; caudal tarsi with the 

 second joint about three-fifths as long as the metatarsus, the third joint but 

 slightly shorter than the first and second joints together. 



General color of dorsal and lateral surfaces cedar green, the abdomen pale 

 cendre green. Head with the margins of the fastigium and of the fastigial angles 

 blackish; ocelli orange-yellow; eyes auburn; mandibles bay, touched with 

 ox-blood red proximad; clypeus and labrum sanford's brown, the ventral 

 margin of the genae weakly and unevenly lined with wax yellow; antennae 

 black, the proximal joint and a dorsal edging on the next five to six joints 

 dragon's-blood red, six distal joints ochraccous-orangc. Pronotum with the 



^2 On one limb there is present in the unique type a distal cxt(>rnal sjjine, a 

 condition not normal in the group.
