Allied to P. paxillus (Westwood)^" and P. periUus Stal.^^ From the 

 former it differs in the absence of distinct spines on the head, the more 

 ovate tegmina, the much longer wings, the slightly longer mesonotum 

 and the lobate posterior femora. From the latter it differs in the larger 

 tegmina and wings, the rather different coloration of the wings, the 

 smaller size, and apparently in the lobate posterior femora, although 

 Stal does not state the condition of the limbs in the specimen examined. 



Size medium; form elongate; surface rugoso-tuberculate. Head 

 longitudinal, equal in width and not broader than the pronotum; 

 occiput with the tubercles rather low and grouped into longitudinal 

 series, the median pair of which diverge posteriorly; eyes globose, 

 rather small, prominent; antennae slightly exceeding the head and 

 thorax in length, basal joint rather oblong, slightly depressed. Pro- 

 notum slightly longer than the head, subequal; anterior and posterior 

 margins truncate; tubercles of even size, disposed in distinct longitudi- 

 nal series ; longitudinal sulcus very slight, transverse sulcus broad and 

 shallow, but very marl^ed. Mesonotum slightly over twice the length 

 of the pronotum, gradually expanding posteriorly, surface rugoso- 

 tuberculate ; metapleura finely rugulose ; metasternum with an irregu- 

 lar median longitudinal carina. Metathorax about as long as the meso- 

 thorax, rather si3arsely tuberculate. Tegmina elliptical; veins irregvi- 

 larly reticulate; median protuberance high, blunt, the posterior portion 

 curved inward toward the anal margin. Wings four times as long as 

 the tegmina, reaching to the middle of the fourth abdominal segment, 

 not quite twice as long as wide; venation rather regular proximally 

 becoming subreticulate distally. Abdomen over half again as long as 

 the head and thorax, the six basal segments longitudinal, the first and 

 second shorter than the succeeding divisions; seventh segment sub- 

 quadrate; eighth and ninth segments distinctly transverse, the latter 

 shorter than the former, and with the apical margin subtruncate and 

 distinctly crenulate; cerci very short, slight and simple, lateral in 

 position; subgenital opercule short, reaching the apex of the seventh 

 dorsal segment, carinate, apex acuminate. Limbs short. Anterior 

 femora about equal to the mesonotum in length, margins crenulate; 

 tibice slightly shorter than the femora, margins crenulate; metatarsi 

 not more than half as long as the remaining tarsal joints. Median femora
