Coleopterous Suh-Family Byrsopmce [CurculionidcE). 83 



5 with a short humeral carina. Legs variegated with grey and 

 brown and with rather long pale setae ; tarsi slender, posterior pair 

 with joint 1 not longer than 2, the latter IJ times as long as 

 broad. 



Cape Colony : Stellenbosch (L. Peringuey). 



Type of quadrata missing (in coll. Wiedemann) ; type of angustata 

 missing (in coll. Drege). 



Very similar to apicalis, Boh., in general appearance, but readily 

 distinguished from it by the contiguous intermediate coxae. B. 

 angustata was evidently described from a small S' - 



22. Byrsops aurivillii, sp. nov. 

 Plate VI., fig. 5. 



Long. 9-5f ; lat. 4|-3 mm. 



Colour black, with uniform earth-brown scaling ; almost devoid of 

 set^e. Head more or less obsoletely punctured, with two oblique 

 carinse, each uniting anteriorly with the superciliary ridge, and thus 

 forming a rough W. Bostrum more or less evidently tricostate 

 above and without distinct punctuation. Prothorax about as long 

 as broad, base and apex of about equal width, the sides rounded, 

 broadest at middle ; upper surface shallowly and sparsely punctured, 

 with a deep central furrow bounded on each side by a straight 

 smooth carina, the external apical foveas variable but usually 

 distinct. Elytra ovate, the shoulders sloping and not prominent, 

 sides rounded, broadest about middle, apical declivity rounded ; 

 distinctly punctato-striate, striae 4 and 5 always, 2 and 3 often, 

 irregular, those on the inflexed margins alw^ays regular ; the alter- 

 nate dorsal intervals more elevated, 6, 4 and the apical half of 2 

 bearing low blunt tubercles, which are often considerably reduced 

 or even partially obsolete, those at the summit of the declivity being 

 rather larger than the others, interval 5 with a low carina at the 

 base. Legs with uniform brow^n scaling and scattered short setae ; 

 tarsi moderately long, joints 1 and 2 subequal, 2 longer than 

 broad. 



Cape Colony: Stellenbosch (L. Peringuey), 



Type in the British Museum. 



I have seen 34 examples of this well-defined species, which 

 is comparatively stable in its essential characters. In the carination 

 of the head, rostrum, and thorax it much resembles B. alveata, Pasc, 

 from which it differs in its narrower elytra, its reduced tubercles, 

 more regular punctuation, and the absence of the smooth lateral 

 patch on the prothorax.
