1904.] OF THE GENUS HIPPORRHINUS. 75 



Upper surface convex, with regular rows of very small granules ; 

 interval 1 with a row of small closely-set tubercles disappearing 

 before apex; interval 2 with a row of distant low elongate 

 tubercles, but those near apex very long and sharp ; intervals 3 

 and 5 with single rows of smaller, rounded, and more closely-set 

 tubercles, becoming very long, sharp, and curved towards apex ; 

 4 and 6 devoid of tubercles, or with only a few isolated ones ; 7 

 with a complete row of sharply conical tubercles, becoming longer 

 and more curved posteriorly ; tubercles bare, often of a I'eddish- 

 brown colour, with depressed dark seta?, the intei'spaces with 

 fulvous scaling, the suture and inflexed mai-gins being white and 

 the disk more or less variegated with white patches. Legs with 

 scattered nai-i-ow white scales ; posterior tarsi with the joints of 

 the same width, 2nd and 3rd subequal in length, 1st longer.

This insect holds an intermediate position between globifer F. and 

 insignis Fahr., approaching very closely to some of the Eastern 

 examples of the latter. Indeed it seems doubtful whether the 

 examination of a long seiies would not i-ender it necessary to 

 regard all three as forms of one very variable species.

Head convex, with shallow punctuation and scattered white or 

 fulvous scaling, forehead with a variable central stria ; anteocular 

 furrows deep. Rostrimi not incised at base, as long as head and 

 prothorax, thick, curved and dilated towards apex. Upper 

 surface plane or slightly convex at base, shallowly excavate near 

 apex, with a broad smooth central line, which is sometimes faintly 

 cai'inate, the sides being distinctly punctui-ed and scattered with 

 dark setai ; lateral sulci not uniting at base, the upper pair 

 obsolete, the lower pair long and deep; scrobes deep, dii'ected 

 beneath base of rostrum ; inferior basal furrow distinct. Antennce 

 with scape not reaching eye ; the two basal joints of funicle sub- 

 equal. Prothorax slightly transverse, apex narrowei- than base, 

 sides rounded, broadest about middle, dorsal anterior margin 

 convex, ocular lobes well developed. Upper suiface convex, 

 moderately closely set with large rounded and rather elevated 

 tubercles, leaving a distinct central furrow containing a veiy faint 

 carina and a narrow curved smooth latei-al line on each side ; 

 tubercles bare, with depressed dark setsB, the interstices with white 

 or fulvous scaling,, in the latter case the central and lateral lines 

 white. Elytra elongato-ovate, $ slightly broader, shoulders 

 sloping, sides not much rounded, broadest about middle, apical 

 processes in both sexes stout, sharply conical and tui-ned slightly 

 upwards. Upper surface convex, with ii'i-egular, and often con- 

 fused, rows of lai'ge granules ; interval 1 with a row of small
