Species of South- African CurculionidiB. 409 



larger, separate, and sharply conical ; 4 and 6 devoid of 

 tubercles ; 7 with a complete row of separate conical tubercles, 

 becoming larger towards apex; scaling dark brown, the 

 suture grey, interval 4 wholly and 6 partly white, reflexed 

 margin entirely white. Legs with dense pale scaling ; 

 posterior tarsi almost devoid of setas, joints of about the 

 same width, second and third subequal, fii'st longer. 



Cape Colony. 



A distinct species, resembling the nodulosus group in 

 general facies, but differentiated by the absence of the boss- 

 like tubercle on the fifth interval on the elytra. Its nearest 

 ally is fctih's, Mshl., which differs in having no carina on the 

 prothorax, in having rows of shallow punctures on the elytra 

 instead of granules, in the absence of tubercles on interval 2, 

 and, finally, mfictilis the distance between intervals 3 and 5 

 is about equal to that between the third intervals on the two 

 elytra, whereas in canalicalatus the former distance is less 

 than half the latter. 



Tlijjporrhinus incisirostris, sp. n. 



Long. 24, lat. 10 millim. 



Head convex, closely and finely punctured, foreliead flat- 

 tened and with a very faint central stria; auteocalar furrows 

 very deep and distinct. Rostrum not incised at base, as long 

 as head and prothorax, moderately curved. Upper surface 

 divided into two portions by a broad and deep transverse 

 incision at about one-third from base ; the whole of tlie basal 

 portion is strongly raised, so as to form a broad, thick, rounded 

 horn, which is distinctly punctured throughout; the upper 

 surface of the anterior portion is broadly excavate, with its 

 edges strongly carinate, and punctured only along the sides 

 and base; upper lateral sulci deep, but narrow and short, 

 ascending the sides of the horn and meeting behind it, but 

 not continued on to the anterior portion ; the lower sulci very 

 broad and deep, entirely lateral, and continued from base to 

 the middle of the anterior portion ; scrobes directed to beneath 

 base of rostrum ; the gence produced into a prominent sharp 

 point; inferior transverse basal furrow absent. Ante/i/ue 

 with scape just reaching eye; the two basal joints of funicle 

 subequal. Prothorax rather broader than long, the length 

 greater than the width at base, which again is a little broa ler 

 than the apex, sides strongly rounded, broadest about middle, 

 ocular lobes almost obsolete. Upper surface almost plane, 

 closely covered with small rounded tubercles, leaving a very 

 indistinct central furrow containing; a short but well-marked
