laterally instead of being somewhat obliquely dilated towards the 

 anterior part; the punctures on the elytra and also the striate 

 costules are similar, but the marginal fringe of hairs is dense and 

 somewhat long. 



Length 9J mm. ; width 5 mm. 



Hab. Transvaal (Lydenburg). 



PLEISTOPHYLLA, n. gen. 



Mentum narrow, parallel, twice as long as broad, apical part 

 plainly sinuate at the centre and with the outer angles slightly 

 rounded, no visible suture between the mentum and the ligular 

 part, labial palpi juxta-lateral, small, apical joint cylindrical ; 

 maxillae somewhat weak, armed at apex with five transversely set, 

 sharp, not hooked teeth, labial palpi long, last joint a little longer 

 than the two preceding taken together, nearly cylindrical, but 

 slightly oblique outwardly at tip, and having there a short, 

 longitudinal impression ; head long, parallel laterally, clypeus very 

 short, parabolic, separated from the frontal part by a semicircular 

 suture, vertical in front, somewhat broadly but briefly triangular 

 there and plainly but not deeply notched at the apex, upper margin 

 reflexed ; labrum entirely obliterated ; eyes very large, very bulging, 

 completely exposed to view from above, the canthus being most 

 rudimentary, almost obliterated ; antennae 10-jointed, club 8- 

 jointed, the last seven joints are very long, somewhat flexed 

 outwardly, and normally set close to each other, but the structure 

 of the one preceding (the third from the base) is very singular, for it 

 is nearly as long as the basal one but much more slender, triangularly 

 dilated at about the median outer part and emits there a laminate 

 joint similar to those forming the club and only slightly shorter; 

 prothorax short with the anterior angles very broadly and the 

 posterior ones very little rounded, not ampliated in the middle, 

 not very convex on the disk, and with the basal part not sinuate 

 laterally, but slightly oblique on each side of the middle ; scutellum 

 parallel, bluntly ogival at the tip ; elytra parallel, with the humeral 

 angles rounded, costulate, not very convex and covering the pro- 

 pygidium ; pygidium one-third broader than long, slightly convex ( $ ), 

 sub-vertical ; anterior tibiae bi-dentate outwardly, intermediate and 

 posterior ones with a stiffly ciliated oblique ridge reaching only half- 

 way across, apical part of posterior tibiae not broadly dilated, spurs 

 long, sharp, set far apart and strongly diverging ; tarsi long, slender, 

 basal joint of hind ones as slender and very little longer than the one 

 following, claws curved and having underneath a lobate^ sub-quadrate
