smallest at the sides, beneath and in front; a sharp ridge rising 

 in the centre and continuous to the apex, l^eside it there are no 

 tubercles, but a few punctures. Scutellum small, quadrate, 

 transversely depressed at the base. Elytra triangular in form, 

 deeper than wide, bisinuate at base, humeral angles prominent, a 

 strong tubercle on each elytron equidistant from suture and base; 

 striate-punctate, the punctui-es large and round, largest and rather 

 square at the sides, smallest at the apex; the suture near the base 

 and till about one-third from the apex strongly humped and tuber- 

 culate, and with long black hairs rising from it, at front and back 

 with shorter whitish hairs; on each side of it on the second inter- 

 stice a bundle of long whitish hairs forming with the posterior 

 one of the hump a small triangle, in all of them a few white scales 

 beneath, also some small patches of whitish scales apically; on 

 the second interstice at a little more than one-third from the base 

 a number of stout setfe; the whole surface is sparsely covered 

 with small oval scales, ranging in colour from testaceous to sooty- 

 black; the sides (which are precipitous) less densely than on the 

 disk and apex. On lower surface, at the sides sparsely covered 

 with testaceous scales, much smaller and darker in the 

 middle; the excavation in the mesosternum fringed with long 

 whitish scales. Legs long, sparsely covered with short setje; the 

 anterior femora about as long as the rostrum, the others shorter, 

 all of them beneath with a low but sharply terminating ridge; 

 tibiae with two minute spurs at the inward apex; tarsi setose, the 

 claw-joint with a few small hairs, the 3rd densely spongiose, 2nd 

 and 1st curled over at their apices so as to leave a funnel between 

 them. Length from eyes to apex of elytra 18, rostrum 10, scape 

 15, first joint of funiculus 5^, second 6| mm. Width across 

 humeral angles 8, muzzle 2 mm. Depth beneath hump 9 mm. 



9. Differs from ^ in having the rostrum shorter, not so 

 suddenly or strongly dilated at the apex, and with stronger 

 punctvires; the scape is not so long, the funiculus with the 1st 

 joint much shorter than the 2nd; the club only densely pubescent, 

 without the bunches of hairs on the 5th to 7th joints. The 

 elytra are not so triangular, the sutural hump is less prominent,
