beyond middle, thence rapidly narrowed to apex, dorsal anterior 

 margin convex, ocular lobes well developed. Upper surface convex, 

 closely covered with low rounded tubercles, leaving a narrow 

 central furrow without any carina ; tubercles bare, with very short 

 depressed dai-k setae, interstices with scattered round white scales, 

 forming denser centiul and lateral stripes. Elytra ovate, shoulders 

 slightly prominent, sides somewhat rounded, broadest about middle, 

 apical processes very short but sharp. Upper surface convex, with 

 deep sulci containing rows of large distant granules ; intervals each 

 with a single row of small, low, rounded and closely-set tubercles, 

 except on the declivity of intervals 2 and 4, where they are more 

 elevated and subcylindrical ; tubercles and granules bare, shiny, 

 each with a short depressed dark seta ; scales large, round, and 

 white, forming small irregular spots and patches, especially 

 towards the sides and apex. Legs thick, coarsely punctured, with 

 scattered white scaling and long black setfe ; tibise strongly curved 

 in male, and the femora and tibise with strong tooth-like granules 

 along their inner edges in both sexes ; posterior tarsi broad, the 

 joints subequal in length and breadth.

Long. 19, lat. 9 mm. 



Head convex on vertex, coarsely punctured, forehead with two 

 large and deep impressions separated by a sharp carina ; eyes 

 surrounded by a distinct impressed ling ; anteocular furrows 

 almost obsolete. Rost7-um about as long as head and prothorax, 

 separated from head by a deep dorsal incision, slightly curved, 

 genas scarcely dilated, so that the sides are subpai'allel throughout. 

 Upper surface with a central furrow which is narrow at base and 

 broader and shallower anteriorly, the adjoining costse indistinctly 

 granulate ; lateral sulci subequal, broad and deep, filled with large 

 white scales and separated by a sharp carina, the upper pair 

 meeting at base ; scrobes directed beneath base of i-ostrum ; 

 inferior basal furrow broad and deep. Antennce with scape 

 scarcely reaching eye ; the two basal joints of funicle subequal. 

 Froihorojx distinctly transverse, apex narrower than base, sides 

 strongly rounded, broadest about middle, dorsal anterior margin 

 subtruncate, ocular lobes very prominent. Upper surface convex, 

 moderately closely set with small rounded tubercles, leaving a 

 narrow and very indistinct centi-al furi'ow without any caiina ; 

 tubercles bare, each with a minute depressed seta; interstices 

 densely clothed with large round white scales. Elytra broadly 

 oblongo-ovate, shoiilders very prominent and subrectangular, sides 

 subparallel to well beyond middle, apical processes absent. Upper 

 surface very convex, with regular shallow sulci containing rows of 

 large granules ; all the intervals with single regular rows of low 

 rounded tubercles, which are more conical, but not larger, on the
