1902.] Catalogue of the Cohoptera of South Africa. 617 



one of the labical is a little loiigev ; the maxillte are rol)USt and 

 produced at the apex into a laminate, somewhat hollow process, 

 curving and rounded at the top and having at its base three sharp 

 horizontal teeth ; clypeus nearly as long as the head, sub-parallel, 

 truncate at the tip ; prothorax longer than in PopiUia and also 

 narrower, a little ampliate laterally in the middle, sinuate past the 

 median part and marginate all round ; scutellum somewhat rounded 

 at the apex ; elytra a Httle more elongate than in Popillia, pygidium 

 and legs similar ; mesosternum without a projecting process. 



This genus was indicated rather than characterised by Erikson for 

 a Senegal species, owing to the curious form of its maxillae. Dr. G. 

 Kraatz, in his Monographic Revision of the RuteHd Genus Popillia, 

 has given a fuller description of the generic difference. 



Another species is known from the Gold Coast. 



Gnatholabis brevis, Blanch., 

 Catal. Coll. Entom., 1850, p. 178. 



Head and prothorax metalhc green, shining ; elytra straw-colour, 

 with a narrow sutural and marginal bronze band, as well as a 

 humeral patch, and a somewhat dark but not infuscate median band 

 on each side, this band is at times partly obliterated, under side dark 

 bronze, antennae, wdth the exception of the club which is black, palpi, 

 and legs ferruginous ; the elytra only are glabrous, the rest of the 

 body, including the legs and the whole pygidium, is covered with a 

 dense, flavescent villose pubescence ; head very rugose, clypeus as 

 long as broad, truncate in front, with the angles shghtly rounded, 

 and slightly ampliated in the median part of the sides ; prothorax 

 finely marginate except in the median part of the base, which is 

 emarginate above the scutellum, covered with deep, closely set 

 punctures, and having a very distinct median longitudinal sulcus 

 interrupted in the centre ; elytra slightly longer than broad, sinuate 

 laterally in the anterior part, and ampliated for a short distance at 

 about the median part, impressed transversely below the scutellum, 

 the humeral and the apical callus are very distinct, the striae are 

 deeply punctured and the intervals are plane in the dorsal part, and 

 impunctate ; pygidium scabroso-punctate and completely covered 

 with the appressed hairs ( 9 ) . 



Length 9 mm. ; width 5 mm. 



Hah. Natal (Durban). 



In this species the infuscate bands on the elytra varies very much ; 

 nearly wanting in some examples, they are very conspicuous in 

 others, and reach from base to apex.
