forehead with two shallow impressions ; anteocular furrows 

 present but not very distinct ; eyes rather prominent. Rostrum 

 a little longer and narrower in S , with a deep transverse incision 

 at base, as long as prothorax only, slightly curved, its sides sub- 

 parallel but with the gense slightly dilated at the apex. Upper 

 surface coarsely punctured, with five narrow undulating carinse 

 of equal height; lateral sulci deep, of equal length, the upper 

 pair meeting at base ; scrobes straight, lateral, parallel to sulci ; 

 inferior basal furrow very deep, Ante7ince with scape scarcely 

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

 transvei'se, apex narrower than base, sides strongly rounded, 

 broadest rather behind middle, dorsal anterior margin truncate, 

 ocular lobes slight. Upper surface slightly convex, with a faint 

 transverse impression near apex, closely set with small rounded 

 tubercles leaving a nairow central furrow without any carina ; 

 tubercles bare, with depressed dark setae, inteistices with dense 

 brown scaling. Elytra ovate, much narrower in c? ? shoulders 

 sloping, sides rounded, broadest about middle, apical processes 

 short, blunt, and parallel in $ , absent in S • Upper surface 

 convex, with row^s of ill-defined shallow punctures often separated 

 by granules ; interval 1 with a complete row of small closely- set 

 granules ; intervals 2, 4, and 6 devoid of tubercles ; 3, 5, and 7 

 with complete rows of small subconical tubercles which hardly 

 increase in size posteriorly, but are rather larger and more distant 

 in the 5 ? especially on interval 3 ; tubercles bare, with short 

 depressed dark setse, interstices with dense brown scaling. Legs 

 with sparse pale scaling, forming a denser ring near apex of 

 femora ; posterior tarsi with 3rd joint a little broader than the 

 others, 2nd and 3rd subequal, 1st a little longer.

 Head convex on vertex, rugosely punctured, with grey scaling 

 and erect dark setse ; forehead subimpressed, with a median 

 carina. Rostrum separated from head by a shallow dorsal incision, 

 as long as prothorax, strongly curved, dilated beyond middle. 

 Upper surface with five carinse, the median one broader than the 

 others and impunctate ; lateral sulci deep, the upper pair rather 

 longer and meeting at base ; scrobes directed beneath base of 

 rostrum ; inferior basal furrow absent. Antennce with scape 

 reaching eye ; the two basal joints of funicle short, subequal. 

 Prothorax broader than long, the length equal to width at base, 

 apex a little narrower, sides moderately rounded, broadest at 

 middle, ocular lobes well developed. Upper surface somewhat 

 convex, unevenly set with small rounded tubercles, leaving a 

 central furrow containing an abbreviated carina ; tubei*cles bare, 

 with long erect dark setae, the interstices with greyish scaling.
