414 Mr. G. A. K. Marshall on new 



IJipporrhinus lobatus^ sp. n. 



Long. 23, lat. 10 millim. 



Head convex, with scattered shallow punctures, vertex with 

 dense scaling, forehead bare and with a central fovea ; ante- 

 ocular furrows distinct and complete. Rostrum not incised at 

 base, about as long as head and prothorax, strongly curved, 

 its upper edge in profile being in a continuous line with the 

 forehead from base to middle, then very shar])ly deflexed, 

 almost at a right angle. Upper surface convex at base, deeply 

 excavate anteriorly, its edges being strongly raised in the 

 form of angulated carina?, punctures large, diffuse, and shallow, 

 leaving a broad smooth central line ; lateral sulci shallow and 

 faint, the upper one very narrow and obsolescent ; scrobes 

 directed to beneath the base of rostrum ; inferior basal furrow 

 absent. Antennce with dense brown scaling; scape not 

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

 thorax transverse, the length about equal to the width at 

 base, the apex narrower, sides moderately rounded, broadest 

 about middle, ocular lobes strongly developed. Upper 

 surface plane, diffusely set with large elevated rounded 

 tubercles, leaving a broad central furrow containing a distinct 

 short carina; tubercles and carina bare, interstices covered 

 with large round whitish scales. Elytra oblong, sides sub- 

 parallel to beyond middle, shoulders prominent but rounded, 

 a strong impression about apex of fifth interval, apical pro- 

 cesses in female short but sharp and divergent. Upper 

 surface slightly convex, striee with rows of small punctures 

 with more or less distinct intervening granules, intervals 

 uneven: interval 1 with a row of distant granules; interval 

 2 with an abbreviated row of tubercles from before middle to 

 apex, those on disk small and rounded, those on declivity 

 much larger and sharply conical ; intervals 3, 5, and 7 with 

 complete rows of small subconical tubercles, which become 

 larger and more conical near apex ; intervals 4 and 6 quite 

 smooth. Tubercles bare and with short pale depressed seta?, 

 interstices with thin brown scaling variegated with grey. 

 Legs with dense pale scaling ; posterior tarsi with the joints 

 of about the same width, first a little longer than second, and 

 second than third. 



Cape Colony. 



A distinct species, though clearly falling into the group 

 represented by ferus, Gyl., and perhaps most nearly re- 

 sembling mammillatus, Gyl. ; but, apart from its much more 

 elongate elytra, the strongly lobate edges of the rostrum will 

 at once distinguish it.
