Coleopterous Sub-Family Byrsopince (Curculionidce). 81 



very obtusely rounded tubercles, those on the anterior half of 

 interval 2 being much smaller than the others and nearly reaching 

 the base, while the tubercle at the summit of the declivity on 

 interval 4 is distinctly larger than the rest; interval 3 with a low 

 basal callus; inflexed margins scarcely sulcate, but with regular 

 rows of large punctures. Legs with very short sparse setae, except 

 along the inner edge of the tibiae, where they are longer and denser ; 

 tarsi elongate, stout and very setose. 



Cape Colony. 



Type in the British Museum. 



This species has been confused with hopei, Boh., in collections, 

 but it is a much more elongate insect than the latter, the tubercles 

 also are larger and more obtuse, especially those at the summit of 

 the declivity, and the second joint of the intermediate tarsi is not 

 transverse. Described from four very similar specimens (2 in the 

 Brit. Mus., 1 at Oxford, and 1 at Paris).

 B. glaucescens, Pasc. I.e. p. 328. 



Long. 51-8J-; lat. 2i-3f mm. 



Colour of type specimen uniform light grey, with two short basal 

 lines and a narrow transverse line at the top of the declivity dark 

 brown ; in the other examples the elytra are light brown above and 

 grey laterally, and there is an additional broad subtriangular brown 

 patch in the middle of the suture. 



Head shallowly punctured and without distinct frontal carinae. 

 Bostrum faintly bisulcate, at least near the base, the dorsal 

 margins subcostate. Prothorax dorsally as long as broad in $ , 

 longer than broad in ^ , sides slightly rounded in the middle, apex 

 scarcely dilated; upper surface with large subreticulate punc- 

 tures, more or less filled with scaling, and with a very shallow, 

 often indistinct, central furrow, the anterior transverse impression 

 distinctly trifoveate. Elytra subovate, the shoulders narrow and 

 very oblique in S' , more broadly rounded in ? , sides moderately 

 ampliated, posterior declivity rather abrupt ; upper surface scarcely 

 sulcate, the first three rows of punctures fairly regular, 4 and 5 

 confused; in the $ the first three intervals are broader and quite 

 plane, whereas in the ^ they are narrow and subcarinate ; interval 2 

 has a small but prominent tubercle at the top of the declivity and a 

 few smaller ones beyond ; interval 4 bears three or four tubercles 

 behind, the one at the top of the declivity being distinctly larger 

 than all the others ; interval 6 bears a complete row of small conical
