2. P. marshalli, sp. nov. 



Eesembling scaber, but smaller in stature, liaving the vertex to- 

 gether with the frontal costa in profile distinctly arcuate, not at all 

 sinuate, the antennae short, articles not strongly elongate, the median 

 carina of pronotum percurrent, little elevated, entire. 



Entire length of body, male, 9 mm.; pronotum 7 '5 mm.; posterior 

 femora 4 mm. 



The antennae are inserted between the lower part of the 

 eyes in this species, as they are in scaber. Were it not for 

 the narrow truncate front margin of the vertex, marshalli 

 might better be assigned a place in the genus Hcdotettix,, as 

 the other charactei'S referred to above ally it with the latter. 



One example from Cape Town, Rondebosch, Aug. 17, 

 1905, collected and presented by Mr. Guy Marshall to the 

 University Musevnn, Oxford. 



The author takes pleasure in naming this species after 

 Mr. Marshall. 



3. P. slielfonli, sp. nov. 



A short-wing form slightly scabrous, colour ferruginous obscurely 

 fusco-bimaculate on the dorsum. Vertex slightly narrower than one 

 of the eyes, fossulate on each side anteriorly ; eyes little elevated ; 

 frontal costa rather flattened convex in profile between the antennae 

 and not sinuate between the eyes, widely sulcate, the rami evenly 

 divergent. Pronotum abbreviated, cuneate posteriorly, and laterally 

 bicarinate on process, the apex not reaching to apex of abdomen in 

 the female ; humeral angles subindistinct ; prozonal carinse not at all 

 expressed ; dorsum subtectiform forward, depressed behind the 

 shoulders ; median carina undulate ; posterior angles of the lateral 

 lobes widely rounded. Elytra of moderate size, widely rounded at 

 the apices; wings abl)reviated, only as long as the pronotal process. 

 Anterior and middle femora compressed, somewhat hirsute ; superior 

 valves of female ovipositor strongly broadened towards the bases, 

 acute, produced toward the apices and armed with denticles. 



Entire length of body, female, 8 mm.; pronotum 6"5 mm. 



One example. No. 1236, from Malay peninsula, Perak, 

 Larut Hills, 4-5000 ft., collected and presented by 

 Mr. R. Shelford to the University Museum, Oxford.

This species is dedicated to Mr. R. Shelford, the dis-
