very deep and approaching one another closely above. Rostrum 

 not incised at base, about as long as head and prothorax, distinctly 

 curved. Upper surface Avith a shallow central furi-ow, triangularly 

 dilated to apex and containing a faint central carina ; lateral 

 sulci deep, the upper pair convergent at base, but not meeting, 

 the interval between the sulci carinate and rugosely punctured ; 

 scrobes directed beneath base of rostrum ; inferior basal furrow 

 shallow. Antennce with scape not reaching eye ; the two basal 

 joints of funicle subequal. Prothorax broader than long, apex 

 narrower than base, sides strongly dilated, broadest about middle, 

 ocular lobes moderate. Upper surface almost plane, with a broad 

 transverse impression jvist behind apex, faii^ly closely set with 

 small rounded shiny tubercles, each bearing a short depressed seta ; 

 central furrow shallow, containing a very short but well-marked 

 carina; interstices with uniform brown scaling. Elytra ovate, 

 shoulders sloping, sides moderately rounded, broadest about middle, 

 apical processes in $ veiy short, blunt, and divergent. Upper 

 siu'face convex, with regular rows of fovese separated by small 

 granules ; interval 1 with a few indistinct granules ; 2, 3, 5, and 7 

 subcostate and with regular rows of granules, which become rather 

 lai"ger on the declivity, but on interval 2 ceasing abruptly at the 

 summit; intervals 4 and 6 plane and without granules; scaling 

 uniform earthy brown. Legs with sparse depressed pale setse on 

 femora and an ill-defined ring of light scales near apex ; tibiee with 

 mingled light and dark sette, the former depressed, the latter erect ; 

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

 3rd subequal in length, 1st longer.

Type in the British Museum. 



Nearly allied to the preceding species, from which it may be 

 distinguished by the absence of granules on intervals 4 and 6 of 

 the elyti"a and the long stria on the forehead.

Long. 20-25, lat. 8-10 mm. 



Head convex, more densely squamose on vei-tex, and with the 

 punctures there fine and closely set, but larger and more scattered 

 in front ; forehead with a very broad and deep central impression, 

 continuous with that on rostrum ; anteocular furrows deep. 

 Rostrum not incised at base, as long as head and prothorax, the 

 upper outline straight to beyond middle, then sharply deflected, 

 dilated from middle to apex. Upper surface with a very broad 

 and deep central furrow throughout, edged on either side by an 

 angulated costa which is continued on to the forehead ; vipper 

 lateral sulcus obsolete, the lower one long and distinct ; scrobes 

 deep, directed beneath base of rostrum ; infei-ior basal furrow 

 absent. Antennce squamose, scape not reaching eye ; the two basal 

 joints of funicle subequal. Prothorax as long as broad, apex 

 scarcely narrower than base, sides rounded, broadest about middle,
