African Phytophagous Goleoptera. 235 



I must separate this species from C. gorterite, Linn., and 

 one or two other similarly marked African forms on account 

 of the shape, number and position of the thoracic spots ; 

 according to Suifrian, G gorteriie has four yellow spots on 

 the thorax and the posterior margin of the latter is deeply 

 serrate, of which I can see no trace in the species before 

 me ; the spot at the sides of the thorax is also of different 

 shape, and there is no trace of a spot at the anterior margin 

 of the thorax. The above description applies to a specimen 

 in my collection from Africa of which I have no detailed 

 locality, the variety I received from Mr. Marshall; it agrees 

 in everything with the type but the median yellow spot of 

 the thorax is absent. 



Gryptocephalus barker i, sp. n. 



Flavous, the antennae (the basal joints excepted) and the breast 

 black, thorax impunctate with four basal and two central black spots, 

 elytra finely punctate -striate, the suture, an angulate transverse 

 band before, another below the middle, the lateral and apical 

 margins (the basal portion excepted) and a spot on the shoulders 

 black. 



Length 5 millim. 



Head minutely and closely punctured, flavous, without impressions, 

 the clypeus rather defiexed, antennae extending to the middle of the 

 elytra, black, the basal five joints flavous, the third and fourth joint 

 equal, shorter than the following ones ; thorax strongly widened at 

 the middle and narrowed anteriorly, the lateral margins nearly 

 straight, the surface very convex, entirely impunctate, bright flavous 

 or pale fulvous, with four rather irregularly shaped black spots at the 

 base, often connected at the basal margin, and a smaller spot at each 

 side at the middle of the disc, scute! lum broadly ovate, black, with a 

 smallfovea atthe base ; elytra slightly narrowed posteriorly, very regu- 

 larly and finely punctate-striate, the punctures piceous, very closely 

 placed, flavous, with two transverse narrow black bands, the first 

 placed before the middle, strongly angulate at the sides in a down- 

 wards direction and not extending to the lateral margins, the second 

 band below the middle, deeply and suddenly constricted near the 

 suture and joined to the lateral band which commences at the middle 

 of the lateral margins and extends round the apex and upwards along 

 the suture to the base, the shoulders also with a black spot ; below 

 and the legs flavous, finely pubescent, the breast and the middle
