 A series. 



The absence of longitndinal lines from the upperside distinguishes this robnst 

 species at a glance from the others. 



Hippopsicon virgatum (1871) Gerst. belongs to Ilyllisia. 



108. Hyllisia loloa spec, no v. 



S ■ Brownish black ; pubescence clay-colour, forming the usual lines on 

 pronotum and elytra, the five pronotal lines not very distinct on account of the 

 clay pubescence covering the interspaces. Puncturation of head, pronotum, and 

 elytra very coarse. Antenna blackish brown, distal segments not obviously more 

 rufous than scape, third segment half as long again as fourth. Lower lobe of eye 

 large, its vertical diameter surpassing that of cheek. Prothorax about one-fifth 

 longer than broad, somewhat rugate in middle. Ape.x of elytra transversely 

 truncate, very faintly sinuate. 



Length, 10 mm. ; breadth, 2i mm.

We have two c?c? of this species, one from Assaba, Niger (Dr. (Jrosse), the 

 other from the Ogowe' R. The species differs from all the others known to me 

 especially in the fine puncturation of the pronotum, the punctures being larger 

 than the interspaces, in the acuminate elytra, the impunctate underside (apart from 

 some large punctures situated behind the anterior coxa) and in the broad and 

 sharply defined yellow infero-lateral vitta of the prothorax. 



The lower lobe of the eye is vertical, its vertical diameter being longer than 

 that of the cheek. This seems to be a male character in this genus, as is also the 

 long antenna, of which the third and fourth segments are almost equal in length. 

 The female antenna is much shorter, has a shorter end-segment, and the third 

 about half as long again as the fourth. 



109. Polyrrhaphis africanus spec. nov. 



S ? ■ Structurally very close to the species of this American genus, differing 

 only in the elytra not being spinose at the truncate apex. Black, clothed with a 

 whitish tomentum ; a broad antemedian area on elytra, widest and most distinct 

 laterally, and head fuscous ; acute tubercles of elytra and a transverse band at apical 

 fourth from disc to disc, interrupted at the suture, black. 



Lower lobe of eye a little broader than high. Pronotum with large punctures 

 in the depressions, a high discal tubercle on each side, a small one mesially before 

 base ; side-spine very long and acnte. Elytra raised at suture, in middle of base 

 and from humeral angle to black transverse band, armed with acnte tubercles on 

 these raised parts. 



Length, 10—22 mm. ; elytra, 11—15 mm. ; breadtli, 8— lOi mm.
