This and the two preceding species are all very closely 

 allied. They are fulvo-testaceous insects about 17 mm. 

 in total length with very long slender antennae and with 

 the tegmina projecting considerably beyond the end of the 

 body; the venation of the tegmina is the same in all 

 species, there being twenty to twenty-one costal veins, 

 eight discoidal longitudinal sectors and the radial vein is 

 bifurcated. 



The following may be considered the differential 

 characters of the three species : 



Pronotum with disc f usco-castaneous, a W-shaped 

 mark and central line testaceous, margins testaceous. 

 Coxte not spotted. Supra-anal lamina narrow, 

 produced, triangular ; sub-genital lamina irregular, 

 deeply cleft ; titillator nearly straight P. elegans 



Pronotum with discrufo-castaneous, a dumb-bell- 

 shaped mark and margins testaceous. Cox as not 

 spotted. Supra-anal lamina incised at apex ... P. 2ncticollis. 



Pronotum fulvous with irregular jialer marking 

 on disc. CoxDe spotted with castaneous. Supra-anal 

 lamina broad, produced, triangular ; sub-genital 

 lamina narrow, not cleft ; titillator strongly curved P. gnttifera.

This is closely allied to P. Mcroglypliim, Br. but the 

 head and pronotum are much more heavily marked with 

 castaneous and the femora have their posterior margins 

 marked with fuscous.

Fulvo-testaceous. Head castaneous, antennre twice as long as the 

 body. Pronotum trapezoidal, barely covering vertex of head, 

 posterior margin very slightly angled, sides only slightly deflexed,
