Coleopterous Suh-Family Byrsopince {Curculionidce). 87 



Cape Colony : Cape Flats and Eondebosch (/. H. Brady), 

 Stellenbosch {L. Peringuey). 



Type in the Upsala University Museum, also (?) the type of 

 thunbergi, Boh. ; types of encausta and vittigera, Pasc, in the 

 British Museum. 



The two long stripes on the elytra give this species a very dis- 

 tinctive appearance and render it easily recognisable. B. encausta, 

 Pasc, is simply a colour variety in which these stripes have more or 

 less merged into one another. The type of retusa, which has lost 

 its head and all its legs, is a small light coloured ^ in which the 

 tubercles are much reduced and the prothorax is rather shorter than 

 usual. I have not seen the type of thimbergi, but the description 

 agrees entirely with vittigera, which represents the more normal 

 form of the species. 



26. Byrsops cuneata, sp. nov. 

 Plate VI., fig. 6. 



Long. 11 ; lat. 4f mm. 



Colour black, with uniform grey scaling, the whole upper surface 

 sparsely covered with very short suberect black setae. 



Head with large shallow punctures and without carinse. Bostrum 

 with a faint central carina and a row of shallow punctures on each 

 side of it. Prothorax elongate, dorsally longer than broad, sides 

 almost parallel ; upper surface with large subreticulate punctures, 

 with a broad shallow central furrow bounded by low undulating 

 carinae, and with an apical fovea on each side of it. Elytra elongate, 

 without shoulders, the basal external angle subrectangular, sides 

 slightly rounded, broadest behind middle, apex abruptly truncate ; 

 upper surface convex, with nine perfectly regular sulci containing 

 large transverse punctures, the intervals simply costate in the basal 

 f and all of almost equal height, the fifth being a little more elevated 

 just at the base where it forms the basal angle ; posteriorly there is a 

 large tubercle at the edge of the declivity on intervals 2, 4, and 

 6 (that on 4 being much the largest), and interval 2 bears three 

 or four very small tubercles on the declivity. Legs with uniform 

 grey scaling and sparse black setae ; tarsi moderately long, 

 posterior pair with joints 1 and 2 subequal, 2 being longer than 

 broad.

A distinct and isolated species which bears an extraordinarily 

 close superficial resemblance to Synthocus loardeni, Per. The broad
