South Afri'an Species 0/ Ilypolitliua. 371 



Eli/tra very little wider at base than base of protliorax, 

 briefly ampliated below slioultler, tlieiiee nearly straight to 

 beyoiul middle ami fxeiitly rouiidcil to apex, stri.e very fine, 

 liardly deeper in male than in female, intervals (juite plane, 

 very iridescent, niinntely and densely aeieulate-punctatc ; 

 conspieuous spaced pnnctures on third, fifth, and seventh 

 intervals. 



Very nearly allied to " H. caffer" cum "• glaber," Boh , but 

 ditlVrentiated as follows : — 



PruthnruA' nearly similar in outline, but more transverse 

 and less contracted to base; posterior part of head and the 

 central frontal part of protliorax conspicuously more convex, 

 and the front angles of the latter umre prominent. Elytra 

 relatively shorter, strire less deep, especially noticeable as 

 between males. Seriate punctures as conspicuous on seventh 

 as on the other intervals. 



Descri[)tion taken from two males and three females. 



Hub. Malvern, Natal, collected by the author. Up to 

 now, I have takrn it at or received it from this locality only. 

 U.glaber cum cajfer also occurs at Malvern as in other places. 



Hypolithus rivalis. Per. 



The co-type (male) of this species [vide Ann. S. Afr. Mus. 

 vol. V. p. 279) belonging to the Durban Museum Collection 

 is before me, and I tind that in some minor details it differs 

 from the author's description. Referring to the remote 

 punctures, so often present on some of the elytral interval*, 

 the description says " insterstitiis tertiis quintoque punctis 

 majoribus scriatis miHis.''^ The co-type has shallow but 

 distinct punctures on the third intervals. No mention is 

 made of the extreme fineness of the striation and punetura- 

 tion of the elytra, which is even finer than that of legitimus, 

 mihi, and glaber, Boh., and in the brightness of the iri- 

 descence it is only equalled by the males of these two 

 species. 



To this species I have tentatively assigned two female 

 specimens collected by me on the Puigwe Kiver, Mozam- 

 bique, which agree exactly with the male co-type in shape of 

 the protliorax, which in this species is very short and broad 

 (a full 3 mm. wide by 2:^ mm. long), and tht-y also have the 

 hind angles subacute ; further the seriate punctures of the 

 elytra are limited to the third intervals only. They are, 

 however, a little smaller and less parallcl-sidrd, and the 

 striation and puucturation arc a tritie deeper and coarser.
