MEXICAN ORTHOPTERA. 223 



Size about the same as .'?. modestn. Vertex deeply snlcate with erect lateral 

 margins, strongly constricted centrally, narrowly separated from the front. Eyes 

 prominent, semi-giobular. Pronotum compressed, subequal, anterior margin very 

 feebly concave, posterior margin roundly truncate, centrally shallowly sulcate ; 

 lateral lobes little longer than deep, the posterior sinus deeply cut, inferior mar- 

 gin broadly rounded, with the anterior angle rather prominent, the anterior 

 margin subsinuate. Tegraina long, but little wider than the length of the pro- 

 notum, margins subequal ; the median vein arising from the discoidal before the 

 middle, and reaching the ulnar vein. Wings longer than the elytra, apex ante- 

 riorly rounded. Anterior and median femora slender, with obscure spines; the 

 tibiae bearing two rows of spines. Posterior femora slender, with few spines; 

 tibise closely spined, the apex with a distinct anterior curve. Anal segment tri- 

 angularly produced between the cerci, the latter tapering, slightly incurved, the 

 apex thickened; subgenital plate moderately produced, bicarinate, and appar- 

 ently apically truncate {the specimen being distorted). 



General color pale green, strongest in the vicinity of the ulnar vein ; lower 

 portion of the lateral lobes of the pronotum very pale, almost whitish ; the dor- 

 sal field of the tegmina with a spot of blackish brown, the space between the 

 anal and ulnar veins being the same color.

Evidently allied to P. maculosa Burnieister from Baliia, but 

 differing in the number of spots on the tegmina, and the absence 

 of heavy purplish coloring on the pronotum. The only other spe- 

 cies with which it might possibly be confounded is P. finoti Griffini 

 from Panama, which has, besides other differentiations, black denti- 

 cules on the cerci. 



Size medium. Head with the vertex broadly sulcate, the lateral margins 

 moderately elevated, contingent with the front, the latter not sulcate, but with a 

 double row of punctures; eyes elliptical much shorter than the infra-ocular 

 gense; antennae surpassing the tegmina. Pronotum with the disk flat, consider- 

 ably expanding posteriorly, the anterior margin concave, the posterior broadly 

 rounded, with a slight central emargination ; lateral lobes inserted at right 

 angles to the disk, deeper than wide, the lower margin subsinuate anteriorly, the 

 posterior sinus moderately deep. Tegmina elongate-ovate, tip rather narrowly 

 rounded. Wings extending beyond the tegmina. Anterior femora above smooth, 

 below with four spines; tibite sulcate superiorly and inferiorly, two spines on the 

 posterior-superior margin, the inferior margins each bearing eight spines. Me- 

 dian femora inferiorly with four rather obsolete spines. Posterior femora infe- 

 riorly with five spines on the external margin, internal with seven ; tibia;
