456 On new Species of South- African Curculionida3. 



row of small, scale-covered, setigerous granules, those on 

 interval 2 slightly cristate on the declivity only. Legs elon- 

 gate, with dense grey scaling and scattered pale setge ; poste- 

 rior tarsi with the second joint a little narrower than the 

 others, second and third subequal, first slightly longer. 

 A7itennce with scape barely reaching eye ; the two basal joints 

 of funicle subequal. 



Cape Colony: Grahamstown {coll. Pascoe). 



This species is closely allied to the aberrant H. thoracicus^ 

 Fahr., from which it is distinguished among other points hj 

 the dorsal angulation of the rostrum, the more deeply excavate 

 head, the more declivous and less strongly costate elytra, and 

 the shorter tarsi ; but the most interesting distinction lies in 

 the direction of the scrobe, which is purely lateral in thora- 

 cicusy but directed beneath the base of the rostrum in 

 aculeatus. 



Hipporrhinus bimacukituSj sp. n. 



Long. 10-5-12, lat. 4-5-5*5 millim. 



Head convex, closely and distinctly punctured, and with 

 thin yellowish scaling ; forehead with a small, bare, smootii 

 spot near base of rostrum ; anteocular furrows absent. Ros- 

 trum not incised at base, as long as prothorax only, scarcely 

 curved. Upper surface convex, with a fine, smooth, central 

 carina and two, much less distinct, on either side; the upper 

 pair of lateral sulci meeting at base, where the central part of 

 the rostrum is sharply raised, so as to form a rudimentary 

 basal tubercle ; the scrobes are shallow, entirely lateral, and 

 oblique; no transverse basal furrow beneath. Antennce 

 rather longer in the male, black, with grey pubescence ; scape 

 reaching the posterior margin of eye ; the two basal joints of 

 funicle subequal. Prothorax in the male a little broader than 

 long, the length being equal to the width of both base and 

 apex ; in the female distinctly transverse, the length being 

 shorter than the width of base or apex ; sides strongly 

 rounded, broadest about middle, ocular lobes almost obsolete. 

 Upper surface convex, closely set with low granular tubercles, 

 each bearing a depressed seta, and leaving a very narrow 

 central furrow, without any carina. Scaling brown, with 

 three narrow white lines, one central, the others lateral. 

 Elytra ovate and acuminate in female, ellipsoidal and narrower 

 in male, jointly rounded at apex, shoulders sloping, sides 

 rounded, broadest rather before middle. Ul)j)er surface 

 convex, with shallow stria? containing regular rows of small 

 punctures ; intervals all equally raised, each bearing a single 

 row of shiny setigerous granules, which are largest near base
