538 Dr. G. A. K. Marshall on new 



Head twice as broad as long, witli a narrow median 

 furrow and set with suberect spatulate setae ; the eyes not 

 very convex, deepest at the middle, strongly produced 

 backwards, the orbits not projecting on the hind Vnargin ; 

 the anterior limiting furrow short, shallow, and gently 

 curved. Rostrum (excluding mandibles) a little shorter 

 than its basal width, the sides straight ; the dorsum flat, 

 with a very shallow median impression on the anterior half 

 and without any carina; the gense not impressed. Ante7in(2 

 piceous, with the scape squamose ; the funicle with joint 1 

 half as long again as 2, the remainder moniliform and 

 sliglitly transverse. Prothorax twice as broad as long, 

 widest at the middle, the sides moderately rounded, not 

 constricted at the base ; the front margin shallowly sinuate 

 on each side for the reception of the eyes, the base gently 

 arcuate, not marginate, and hardly broader than the apex ; 

 the dorsum strongly convex transversely, but plane longi- 

 tudinally, quite even and without any median sulcus or 

 carina; the spatulate setse subrecumbent and forming a 

 sparse fringe along the basal and lateral margins. Elytra 

 broadly ovate, widest at the middle, jointly truncate at the 

 base and there but little wider than the prothorax at its 

 widest, and very broadly rounded behind; the stria3 scarcely 

 perceptible, and the feeble punctures in them entirely 

 liidden by the scaling ; the intervals broad and each with a 

 row of long, flattened, subrecumbent setse ; the scales small, 

 varying in shape, fitting very closely together, and of about 

 the same size as those on the prothorax. Legs : front tibise 

 with an apical row of five stout spines (often broken off) 

 and two closely juxtaposed spines at a little distance up the 

 outer -edge ; the corbels of the hind pair narrowly enclosed 

 and densely squamose. Sternum with the front coxse in the 

 middle of the prosternum ; the mesepisterna narrowly 

 separated from the elytra. 



Length 2 '5-3 6 mm., breadth 1*3-1 '9 mm. 

 Transvaal : Kinross, xi. 1920. 



Described from ten specimens, forwarded by the Division 

 of Entomology, Pretorin, with the information that the 

 adults were injuring the foliage of maize and potatoes. 



Nearly allied to P. noocius, Mshl. (Bull. Ent. Res. x. 

 ]920 pi. xix. fig. 1), but that species differs, inter alia, in 

 having the basal margin of the elytra a little narrower than 

 the prothorax, deeply sinuate, and with the outer angles 

 slightly projecting; the striae are more distinct, and the 

 punctures are visible through the scaling.
