The black stitural mark varies very much in size ; in one of tiie specimens 

 from Gaboon this patch is almost absent.

Bla<'k, antennae and tibiae with a very feeble tint of pitchy. Tlie scale-like 

 white hairs absent from the antennae except the scape. Disc of the prothora.x 

 with a faint impression on each side. Scutellum as long as broad, rounded, covered 

 with a very dense whitish pubescence, except in the middle of the base. Elytra 

 rather inconspicuously spotted witli greyish-wliite hairs, esj)ecially at the sides ; 

 the punctured rows are not quite regular ; the extreme base and the ajiex irregularly 

 puuctui-ed, with the anterior border of the basal punctures each raised into a feeble 

 granule ; interstices of the punctured rows somewhat raised near the suture. 

 Under surface uniformly pubescent ashy grey.

ISO. Aderpas brunneus Thoms. 

 A good immber of specimens from Ktulu and Gaboon seem to me to belong to 

 this species. Each elytron has four real keels, two of which are feeble, whilst the 

 other species of this genus bear some frequently interrupted lines formed by an 

 erect pubescence. Ou the top of the keels are rather strong setulose hairs, which 

 also may be found — but are much less conspicuous— in A. li /n'.olat u.i (Qhew.i and 

 in A. sabjasciaftis sp. nov.
