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 94 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 lgular 
part, labial palpi juxta-lateral, small, apical joint cylindrical; 
maxillee 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; antenne 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 (3), 
sub-vertical; anterior tibie bi-dentate outwardly, intermediate and 
posterior ones with a stiffly ciliated oblique ridge reaching only half- 
way across, apical part of posterior tibize 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
