Species of South- African Curculionidge. 411 



angulation ; tubercles black, shiny, and without setae. Elytra 

 ovate, shoulders sloping, sides moderately rounded, broadest 

 about middle, apical prominences long, sharp, divergent and 

 turning rather upwards. Upper surface convex, with regular 

 rows of small granules, often separated by large, shallow, indis- 

 tinct punctures : intervals 1, 2, 4, and 6 plane and smooth ; 

 interval 3 with a complete row of shiny brown tubercles, 

 as far as the declivity these are small, rounded, irregular, and 

 often duplicated, but on the declivity they are large and 

 sharply conical ; interval 5 with a perfectly regular and 

 closely-set row of small, rounded, brown tubercles from base 

 to about middle, where it terminates quite abruptly ; interval 

 7 with a complete row of small subconical tubercles ; tubercles 

 bare, shiny, and without setaj. Legs with pale scaling; pos- 

 terior tarsi rather narrow, setose, the joints of about the same 

 width, second and third subequal, first much longer. 



Cape Colony. 



I have received a single example of this distinct species 

 from my friend Dr. Walther Horn, of Berlin, and there are 

 two others in the British Museum from Jekel's collection. 

 Its only near ally is H. ruhifer, F. ; but this species lacks 

 the lateral smooth spaces on the prothorax ; the tubercles on 

 the elytra are larger and further apart, the row on interval 5 

 is complete and not abruptly interrupted, and interval 2 always 

 has a row of four or five large, depressed, and widely separated 

 tubercles. 



Hipporrhinus iricostatuSj sp. n. 



Long. 13, lat. 6 millim. 



Head convex, finely and dispersely punctured, forehead 

 with a small central fovea ; anteocular furrows shallow and 

 ill-defiued. Rostrum not incised at base, about as long as 

 head and prothorax, deflexed and slightly curved. Upper 

 surface without any furrow or carina, convex at base and 

 faintly impressed towards apex, distinctly punctured except 

 for a broad smooth central line ; lateral sulci not meeting 

 at base, which is continuous with forehead, the upper pair 

 narrow but distinct, the lower pair almost obsolete ; aerobes 

 slightly curved, oblique and directed to beneath base of ros- 

 trum ; inferior basal furrow absent. Antenncv with scape not 

 reaching eye; the two basal joints of funicle subequal. Pro- 

 thorax as lung as broad, the length much greater than the 

 width at base, which is about equal to that at apex, sides 

 gradually but strongly dilated from apex and suddenly nar- 

 rowed near base, broadest far behind middle, ocular lobes 

 strongly developed. Ui»per surface plane, with a very high,
