curved and dilated towards apex. Upper surface almost plane at 

 base, or with a faint central furrow which broadens and deepens 

 towards apex, closely but shallowly j)unctured and Avith sparse 

 fulvous scaling ; lateral sulci not uniting at base, of about equal 

 length, but the lower much broader and deeper than the upper ;. 

 scrobes deep, directed beneath base of rostrum ; inferior basal 

 furrow distinct. Antennce comparatively short, the scape not 

 nearly reaching the eye ; the two basal joints of funicle subequal 

 or with the first joint slightly longer. Prothorax a little longer 

 than the width at base, apex narrower, sides slightly dilated and 

 with a sharp spine before middle, dorsal anterior margin truncate, 

 ocidar lobes well developed. Upper surface slightly convex and 

 with a more or less distinct transverse impression near apex, 

 moderately closely set with large rounded tubercles, leaving a 

 broad shallow central furrow containing a short carina ; tubercles 

 bare, each wdth a very short depressed dark seta, the interstices 

 with dense fulvous or greyish scaling. Elytra oblongo-ovate, 

 shoulders sloping, sides moderately rounded, broadest about middle, 

 apical processes sharply conical and divergent in $ , blunt and 

 much shorter in S • Upper surface convex, with regular rows of 

 distinct granules instead of punctures, the intervals evenly raised ; 

 interval 1 granvilate ; 2 with an interrupted row of tubercles which 

 become larger and siibcristate on the declivity ; 3, 5, and 7 with 

 complete, and usually duplicated, rows of rounded tubercles which 

 become more conical apically ; 4 and 6 with only a few isolated 

 tubercles ; tubercles bare, usually with depressed pale setfe, the 

 interspaces with rather thin tawny or greyish scaling and two 

 conspicuous paler patches at the summit of the declivity. Legs 

 with sparse pale scaling and a denser ring near apex of femora ; 

 posterior tarsi with the joints of about the same width, 2nd 

 and 3rd subequal in length, 1st longer.
