Soulh Afncdti Sjiecies of ITypolitliU'^. 3(»5 



as. Leii;jrth GJ- nira.; width 3 mni. ]?l;ick, 



shiny, sniootii ; bLiieath obscurely 



l'enu>riiious ; niiteiiii;r. j>alpi, and lo^^s 



testaceous yellow ; prothorax wide, 



niartriiH'd with testaceous, etc. (vide 



p. I'Ol, liisecta CatTraria, JJoheniaii). 



Diiueiisioiis ns given above ditTer- 



eiitiates it from any Hijpitlithus 



knowu to me, otherwise hardly separ- 

 able from jn-oin'iKjuus *//. mefduchnlicus, Boh. 



39 (41). Head relatively smaller, less retracted 



within thorax, oblong-ovato, convex 



species. 

 •40(41). Length 7 mm.; width 3 mm. Black, 



very iridescent, rarely not so ; legs 



testaceous yellow, tibiaj and tarsi a 



shade darker ; anteiinje ilavous with 



all joints, except two Hrst, lineated 



abi've with fuscous. Spaced punc- 

 tures faintly defined on tnird interval 



or absent 2f. difficilis, I'tSr. 



41 (40). Length 7-7i mm.; width 2J-3mm. A 



tritie less ovate; prothnrax similar, 

 but with posterior angles acute in- 

 stead of rounded. L)ark metallic 

 green, iridescent ; elytra with a short 

 posterior sutural and lateral yellow 

 band H. scitus, Per. 



42 (41). Length 1 2 mm. ; width 4^ ram. Descrip- 



tion, vide Trans. 8. Afr. Phil. Soc. 

 vol. viii. p. 4.">7. Markings and colo- 

 ration appear to be like those of 

 " scitus,^' but it is a much larger 

 insect. Quite unknown to me .... *II. oruatus, Per. 



Ilijpolithus holosericeus, Dej., aud H. marginicollis, Boli. 



Peringuey (Trans. S.A. Phil. Soc. vol. vii. p. 434) states 

 that he cannot differentiate the former from the latter, 

 though he admits that "Holosericeus''^ is a little larger. He 

 gives the following as the dimensions of his ^^holosericeus": — 

 Length 11-13 mm., width 4^-5 mm. Boheman for his 

 "marginicollis^^ gives 12x5 mm. The sjjccies determined 

 for me by Dr. Peringuey many years ago as H. holosericeus, 

 Dej., is a mnch smaller insect than the above, ten examples, 

 including both sexes, range from 9^-11 mm. long by 

 3;^-4| mm. wide, and only cue female example attains the 

 maximum of 11 mm. 



As 1 am not in a position to compare this race with 

 Dejean's '* holosericeus " and Boheman^s " marginicollis^^'' I 

 am giving below a description of it, which in addition to its 

 deficiency in size shows some further minor differences.
