1904.] OF THE GENUS HIPPORRHINUS. 115 



surface convex, closely set with small flattened granular tubercles, 

 leaving a narrow shallow central furrow without any carina ; 

 tubercles black, shiny, each with a depressed seta, interstices with 

 dense brown scaling. Elytra ( 2 ) ovate, acuminate posteriorly, 

 shoulders sloping, sides distinctly rounded, broadest rather before 

 middle, apical processes absent. Upper surface almost plane on 

 disk, with regular shallow sulci, containing indistinct punctures 

 separated by small granuJes, both disa]3pearing behind middle and 

 normally hidden by the uniform dense brown scaling ; intervals 

 all similar, slightly convex, with irregular rows of faint granules 

 which disappear towards apex, the granules bearing depressed pale 

 setse which are continued in rows where the former have dis- 

 appeared. Legs with scattered brownish setae ; posterior tarsi 

 broad, spongy, and with the joints of equal width, the 3rd longer 

 than 2nd and almost as long as 1st. 



" Caffraria." 



Type in the Stockholm Museum. 



Schbnherr placed this species in the section of the genus 

 having the " rostrum ad basin quasi abscissum," but although the 

 elevation of the base of the rostrum gives it somewhat this 

 appearance, its structural affinities are rather with those species 

 with which I have associated it. In the group typified by 

 verrucosus L. this incision sepai'ating the head from the rostrum 

 is caused by the dorsal union of the deep anteocular furrows ; 

 this is not the case with constrictus, in which those furrows are 

 entirely absent.

Head convex, closely and finely punctured, forehead flattened 

 and with a very faint central stria ; anteocular furrows very deep 

 and distinct. Rostrum not incised at base, as long as head and 

 prothorax, stout, moderately curved, dilated apically, the gena^ 

 being produced into a sharp prominent point. Upper surface 

 divided into two portions by a broad and deep transverse incision 

 at about one-third from base ; the whole of the 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 ; lateral sulci very broad and deep and continued 

 from base to the middle of the antei-ior portion ; scrobes directed 

 beneath base of rostrum ; inferior transverse basal furrow absent. 

 AntenncB 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 is a little broader than 

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