indistinctly punctured and covered with bi'own scaling ; upper 

 lateral sulci narrow, uniting at base, which has a small callus on 

 each side above the anteocular furrows, lower lateral sulci broader 

 and longer ; scrobes directed to beneath base of rostrum ; inferior 

 basal furrow absent. Antenuce with the scape just reaching eye ; 

 the two basal joints of funicle subequal. Proihorax about as long 

 as the width at base, apex rather narrower, sides dilated and 

 obtusely angulated about middle, anterior margin dorsally trun- 

 cate, ocular lobes well developed. Upper surface almost plane and 

 with a transverse impression behind apex, faii'ly closely covered 

 with small rounded tubei-cles, leaving a distinct central furrow 

 containing a short but strong carina ; tubercles bare, with 

 depressed pale sette, interstices with dense brown scaling. Elytra 

 oblongo -ovate, shoulders sloping, sides slightly rounded, broadest 

 about middle, apical pi'ocesses very shoit and obtuse. Upper 

 surface convex, with regular rows of shallow punctui-es separated 

 by small granules ; intervals uneveu, the tvibercles all small and 

 subequal throughoiit ; interval 1 with a row of granules vanishing 

 behind middle ; intei'val 2 with a few tubei'cles near base and a 

 shoi't subcristate row on the declivity ; intervals 3, 5, and 7 with 

 complete rows of small closely-set tubercles ; intervals 4 and 6 

 plane, or at most with one oi- two isolated tubercles ; tubercles and 

 granules bare and each with a depi'essed pale seta, interstices 

 clothed with elongate setiform brown scaling. Legs with sparse 

 pale scaling and sette, forming a denser ring near apex of femora ; 

 posterior tarsi with the joints of the same width, 2nd and 3rd 

 subequal in length, 1st distinctly longer.

Head convex, closely but shallowly punctured and with dense 

 brown scaling, forehead with a broad and deep depression ; ante- 

 ocular furrows deep, but entirely lateral in position. Rostrum 

 not separated from head l)y a deep dorsal incision, about as long 

 as head and prothorax, distinctly cui-ved. Upper surface with a 

 shallow central furi-ow throughout, its edges carinate to beyond 

 middle, with close shallow punctuation and dense brown setse ; 

 lateral sulci deep, the upper pair meeting at base, where there is a 

 slight callus above the anteocular furrows, the lower pair rather 

 longer and broader ; scrobes directed to beneath base of rostrum ; 

 infei'ior basal furrow absent. Antennm with the scape not 

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

 transverse, the length about equal to the width at base, apex 

 nai-rower, sides dilated a,nd bluntly angulated about middle, 

 dorsal anterior margin slightly convex, ocular lobes well developed. 

 Upper surface rather convex, with a transverse impression behind 

 apex, unevenly set with small rounded tubercles, leaving a centi-al
