male but less so in the female, in the deflexed part, where the punc- 

 tures are deep and slightly scrobiculate, the white dots are very 

 numerous ; pygidium numerously dotted with white ; the sides of 

 the abdomen and pectus are similarly dotted. 



Length 10|-11 mm. ; widtb 6-7 mm.

 Sitz. Ges. naturf. Freund., Berlin, 1893, p. 75. 



Dull dark brown in the male, olivaceous grey in the female, 

 glabrous, opaque ; antennae piceous ; clypeus aciculate, frontal part 

 deeply but only moderately closely punctate ; prothorax covered in 

 the discoidal part with small, round punctures separated by an 

 interval about equal to their own diameter, but on the sides the 

 punctures are sub-contiguous, deep, and scabrose, on the disk are 

 five rows of minute white dots resembling those of P. furfurosa, but 

 still smaller, the lateral row is indistinct ; scutellum punctate late- 

 rally ; elytra plainly acuminate behind, sprinkled with very 

 numerous white dots ; the two dorsal costae are rounded, sub- 

 tectiform, the punctures in the intervals and on the deflexed side 

 are arcuate ovate, not closed behind and cicatricose, clypeus splashed 

 with white ; under side covered laterally with a slightly fleshy-white 

 coating ; anterior tibias bi-dentate but with a distinct sinuation above 

 the upper tooth. 



Length lOi-ll^ mm.; width 6-7 mm. 



Hab. Southern Ehodesia (Umtali, Enkeldoorn, Sebakwe, Mount 

 Chirinde) ; Mozambique (Beira). 



LIPOTHYEEA, n. gen. 

 Buccal organs of Leucocelis ; head and prothorax of the same 

 shape, the latter, however, is not quite straight above the scutellum ; 

 the elytra are very little attenuated behind, although deeply sinuate 

 laterally, but the shoulders bulge as much beyond the epimera as 

 in Leucocelis; the suture is not so sharply carinate, and is not 

 sharply angular at apex ; there are on each side two costas, little 

 raised m the anterior part, more so in the posterior where the 

 intervals are geminate ; the pygidium is arcuate instead of being 

 acuminate truncate ; the abdomen is less compressed laterally, and 

 the sternal process which is not constricted between the middle 

 coxae is plane, acuminate rounded, and projects as far as the centre
