TWO STEW SPECIES OF ORTHOPTERA REHN. 



397 



Size medium; form moderately robust. Head with the dorsal sur- 

 face about two-thirds the length of the pronotum; occiput well 

 rounded, but hardly elevated, distinctly descending- to the inter- 

 ocular space, which is very narrow, narrower than the apex of the 

 fastigium and sulcate; fastigium truncate conic, the caudal width less 

 than the length and the distal truncation very abrupt and marked 

 immediately caudad of the margin by a transverse groove; median 

 portion of the fastigium with a depression regularly widening ceph- 

 alad. apex of fastigium when seen from the lateral aspect sub-trun- 

 cate; frontal costa somewhat expanded ventrad of the insertion of 

 the antenna?, then strongly contracted ventrad of the ocellus, some- 

 what punctuate dorsad of the ocellus, sulcate ventrad of the same, the 

 whole costa absent, on the ventral portion of the face; angle of the 

 face distinctly retreating; eyes subovate, very distinctly longer than 

 the infra-ocular portion of the gense, quite prominent when viewed 

 from the dorsum. Pronotum with the caudal width of the disk con- 

 tained about one and one-half times in the length of the same, cephalic

margin of the disk produced mesad with a distinct central emargina- 

 tion, caudal margin very broadly obtuse-angulate ; transverse sulci 

 four in number, the cephalic being marginal in position and weak 

 mesad, the remaining three strongly impressed, the two caudal ones 

 present, as is the cephalic, on the. lateral lobes; metazona slightly 

 more than half the length of the prozona, strongly punctate and 

 with a distinct median carina; lateral lobes slightly longer than 

 deep, the cephalic and caudal margins oblique, subparallel. ventral 

 margin obtuse-angulate. the ventro-caudal angle slightly produced. 

 Tegmina reaching to the apex of the abdomen, apex rotundato-trun- 

 cate; an intercalary vein present in the distal portion of the apex, 

 the median and proximal portions with irregular cells. Prosternal 

 spines very blunt pyramidical; interspace between the mesosternal 

 lobes subquadrate, slightly broader caudad than cephalad; metasternal 

 lobes subcontiguous. Apex of the abdomen very considerably in- 

 flated; supra-anal plate regularly narrowing, with the apex broadly 

 truncate, the proximal half plane and slightly depressed, the distal
