1904,] OF THE GENUS HIPPORRHINUS. 39 



Rostrum separated from head by a deep transverse incision, as 

 long as prothorax only, distinctly curved, sides snbparallel through- 

 out, but with the gense slightly dilated. Upper surface convex, 

 with five smooth, narrow, rather undulating carinse ; upper lateral 

 sulci meeting at base, broader and rather longer than the lower 

 pair ; scrobes deep, lateral and oblique ; inferior basal furrow 

 very deep. Antennce with grey setse, scape just reaching eyes ; 

 the two basal joints of funicle subequal. Prothorax broader than 

 long, apex narrower than base, sides not much rounded, broadest 

 rather before middle, dorsal anterior margin truncate, ocular lobes 

 moderate. Upper surface convex, without any central furrow, 

 not very closely set with small rounded tubercles ; each tubercle 

 with a very short depressed pale seta, the interstices filled with 

 brown scaling. Elytra very broad ovate, shoulders rounded but 

 very prominent, the width there nearly twice as great as that of 

 prothorax, sides rounded, broadest before middle, apical processes 

 in 5 short and tuberculiform. Upper surface convex, with 

 regular shallow sulci containing rows of minute granules ; intervals 

 all similar, bearing regular and complete rows of large and often 

 subconical granules ; each granule with a depressed dark seta, 

 the interspaces variegated with patches of large round brown 

 scales. Legs stout, coarsely punctured, and with scattered pale 

 setae ; the inner edges of the tibise strongly dentate, including 

 the posterior pair ; the posterior tarsi very setose, the joints sub- 

 equal in length and breadth.

Type in the South African Museum. 



I have seen only a single $ of this very distinct species, which 

 differs notably from the allied heavy-bodied species of the genus 

 in the very small size of the prothorax as compared v/ith the 

 elytra,

Head convex on vertex, dispersely and faintly punctured, fore- 

 head with a shallow impression on either side ; anteocular furrows 

 short but distinct. Rostrum about as long as prothorax, cut ojS" 

 from head by a deep transverse basal incision, curved, gi^adually 

 dilated towards apex. Upper surface with five low strongly 

 punctured carinse (sometimes the central one is less pxmctate than 

 the others) ; lateral sulci deep, about equal in length, the upper 

 pair uniting at base ; scrobes broad and deep, lateral but oblique ; 

 inferior basal furrow very deep. Antennce with scape scarcely 

 reaching eye ; the two basal joints of funicle subequal. Prothorax 

 distinctly transverse, apex rather narrower than base, sides strongly 

 rounded, broadest rather behind middle, dorsal anterior margin 

 truncate, ocular lobes slight. Upper surface convex, with a
