former narrowing very gradually to the broadly rounded apex, 

 veinlets very numerous and coarse, even in stridulating field, stri- 

 dulating vein obsolete. Wings parachute-like, fully developed. 

 Prosternum bispinose. Mesosternal lobes acute-angulate, meta- 

 sternal lobes rounded, truncate caudad. Ultimate tergite weakly 

 produced with lateral margins straight and very strongly convergent 

 to median portion, which is shallowly and transversely emarginate, 

 the proximo-lateral angles of this emargination rounded and its 

 basal margin transverse. Below this portion is the rotundato- 

 trigonal supra-anal plate. Cercus cylindrical, weakly incurved, 

 tapering to the rounded apex, which is surmounted by a minute 

 tooth, directed mesad. Subgenital plate rectangulate-emarginate 

 distad, the lateral apices each bearing a heavy, straight style, nearly 

 four times as long as broad. Femoral genicular lobes unispinose. 

 Ventral femoral margins armed with the following number of spines. 

 Cephalic internal 4, cephalic external 0, median internal 0, median 

 external 4 and 5, caudal internal 7 and 9, caudal external 10 and 11. 

 Cephalic tibiae with auditory foramina flattened conchate, but with 

 slit wider than is usual in this type, these members flattened dorsad. 

 Armament of tibiae as in P. notatus. Cephalic tibiae with an 

 apical spine dorsad on each side and with two other spines on 

 external margin. Caudal tibiae armed distad with three pairs of 

 spurs. 



General coloration chamois. 42 Head with entire occiput suffused 

 with blackish mummy brown; suture at base of antennal scrobes, 

 twin subocular flecks and a median pair of weak suffusions on face 

 and clypeus also this color. Pronotum with cingulate caudal 

 margin blackish mummy brown, the adjacent portions of the disk 

 and of the tegminal stridulating field suffused with this color as 

 well. Tegmina with minute intervals between veinlets appearing 

 slightly darker and with a few exceedingly weak brownish suffusions 

 along the sutural margin. Wings brownish buff. Femora with 

 spines blackish mummy brown, these members suffused with this 

 color at apices also. 



Length of body 38, length of pronotum 7.8, caudal width of pro- 

 notum 5.9, depth of pronotal lateral lobe 5.1, width of pronotal 

 lateral lobe 5.8, length of tegmen 42.2, median width of tegmen 11, 

 distal width of tegmen 7.8, length of cephalic femur 14, length of 

 caudal femur 33 mm. 



The type is unique.

42 The sinistral caudal femur distad and the proximal portion of the sinistral 

 ■caudal tibia are washed with light green. This appears to be a stain rather than 

 the survival in a dried specimen of patches of green, which specimen in life was 

 of a general green coloration.
