and also the sides of the prothorax have a very short, somewhat 

 greyish, inconspicuous pubescence, the elytra are glabrous ; the 

 clypeus is straight in front with the outer angles moderately 

 rounded, the suture is sub-carinate laterally and almost obliterated 

 in the centre, and the whole head is very finely and very closely 

 punctured; the prothorax is as finely and as closely punctured as 

 the head and has a plain longitudinal groove in the anterior part ; 

 scutellum very finely punctulate ; elytra sub-parallel, somewhat 

 coarsely punctured, plainly coriaceous, and with three fairly dis- 

 tinct striae on each side, in addition to the sutural stria ; pygidium 

 sloping and clothed with a very short appressed pubescence ; ab- 

 domen with a similar pubescence ; pectus clothed with a dense 

 greyish-flavescent and long pubescence ; antennal club 5- jointed, 

 the fifth joint of the pedicel is laminate and one-fourth the length 

 of the club, the fourth is very angular, and the third bead-like, but 

 -also slightly aculeate in the centre. 



Female : More massive than the male, and with the elytra deeply 

 sinuate laterally in front of the median part, and conspicuously 

 ampliated thence ; the clypeus has the outer angles more broadly 

 rounded than in the male, the suture is not interrupted in the 

 middle, nor carinate laterally, and the anterior frontal part is deeply 

 depressed ; the punctures on the prothorax are deeper and broader, 

 and the median impressed line is continued further towards the base ; 

 the elytra are not so coriaceous, the punctures are equally deep 

 but rounder, the dorsal striae are obliterated, and the sutural one 

 ill-defined ; the pubescence on the pygidium and under side is the 

 same as in the male, the posterior tibiae are broadly dilated, and the 

 spurs also broadly dilated, and spear-shaped ; there are wings under 

 iihe elytra; the club is 5-jointed, fairly long, but thick, ovate, and 

 with the two apical joints, especially the last one, shorter than any 

 of the other three. 



Length 31-33 mm. ; width 16-20 mm.

PLEIOPHYLLA, n. gen. 



Buccal organs of Macrophylla and JEgostetha, which it closely 

 resembles, the anterior tibiae are also tri-dentate outwardly and have 

 no inner spur, the antennal club, however, consists of six long, 

 curved, laminate joints, and the fourth joint of the pedicel is also 

 similarly laminate but moderately short ; the inner tooth under the 

 anterior claws is very long.
