ai'e also much more oblique, and the scaling is different, being 

 much thinner, with the scales large, round, and white. 



HiPPORRHINUS IMPRESSICOLLIS, Sp. nov. 



Long. 12|, lat. 34- mm. 



Colotu' black, moderately shining, and entirely devoid of scaling, 

 except for a small white spot at the extreme apex of the elytra. 



Head convex, with scattered shallow punctuation ; forehead with 

 two faint longitudinal impressions ; anteocular furrows deep. 

 Rostrum about as long as head and prothorax, cut off from head 

 by a dorsal incision ; sides parallel to middle, thence gradually 

 dilated to apex ; upper surface convex, with five distinct nai-row 

 carinfe, the outer one on each side abbreviated apically, the basal 

 margin impressed in the middle and obtusely elevated laterally ; 

 lateral sulci broad and deep, subequal in length, the upper pair 

 only imiting at base ; scrobes very deep, lateral, almost straight ; 

 inferior basal furrow very deep. Antennce with scape scarcely 

 reaching eye, the two basal joints of funicle equal. Prothorax 

 a little broader than long, of equal width at base and apex ; sides 

 moderately rounded, broadest about middle, dorsal anterior margin 

 truncate ; ocular lobes feebly developed ; upper surface almost 

 plane, gradually elevated posteriorly and steeply decliyous along 

 the basal margin, closely set with low rounded tubercles, leaving 

 a narrow central furrow which, owing to the posterior elevation, 

 appears much deeper towards the base and contains a fine abbre- 

 viated carina; tubercles each with a very short depressed dark 

 seta. Elytra elongato-ovate in S , shoulders rounded ; sides very 

 slightly ampliated, broadest before middle ; apical processes absent ; 

 upper surface convex, with shallow sulci containing legular rows 

 of distinct granules ; all the intervals evenly raised, convex, with 

 regular rows of depressed and often elongate granules, each bearing 

 a very short depressed dark seta, except on the declivity, whei-e 

 the setse are long and erect. Legs comparatively long and slender, 

 with scattered dark setse ; posterior tarsi with the 1st joint longest 

 and as broad as 3rd, 2nd rather narrowei" but as long as 3rd. 



Oape Colony : Stellenbosch (Z. Peringuey), Malmesbury [R. M. 

 TAghtfoot). 



Type in the South African Museum. 



In general facies this species most resembles H. capensis L., but 

 its rostrum is much more slender and distinctly dilated at the 

 apex ; moreover, the gradual posterior elevation of the jDrothorax 

 and its unusually deep central f uri'ow will distinguish impressicollis 

 fi'om all its nearest allies. 



HiPPORRHINUS monilis, sp. nov. 



c? long. 10-17, lat. 4-7; $ long. 11, lat. 5 mm. 



Head convex, bare, with scattered large deep punctures ; fore- 

 head plane and somewhat plicate ; anteoculai- furrows, as seen 

 from above, very deep. Rostrum a little shoitei- than prothorax.
