and faint ; scrobes directed beneath base of rostrum ; inferior 

 basal transverse furrow obsolete. Antennce with dense pale 

 scaling and black sette ; scape not nearly reaching eye ; the two 

 basal joints of f unicle subequal. Prothorax as long as broad, apex 

 narrower than base, sides slightly dilated and with a small tuber- 

 cular angulation before middle, ocular lobes strongly developed. 

 Upper surface convex, with a broad lance-shaped central furrow 

 containing a low cai'ina and flanked on either side by two rows of 

 closely but iri'egularly placed tubercles ; beyond these a smooth 

 longitudinal space, followed by a single regular row of tubercles 

 close to the latei'al margin, and below this another similar row, of 

 which a single tubei'cle is rather larger than the others and forms 

 the lateral projection ; scaling on disk brown, but greyish in 

 central furrow and on prosternum. Elytra oblongo- ovate, shouldei-s 

 I'oundedly pi^ominent, sides veiy little rounded, broadest about 

 middle, apical processes long and sharp. Upper surface convex, 

 with regular rows of large deep punctures, the alternate in- 

 tervals dissimilar; intervals 1, 2, 4, and 6 devoid of tubercles, 

 except a single small one near the base of the latter ; intervals 3 

 and 7 with complete rows of conical tubercles, which become more 

 distant, larger, and sharpei- towards apex ; interval 5 with a very 

 lai^ge, rounded, boss-like tubercle at base, followed by six closely- 

 set conical tubercles, and a solitary lai-ger and sharper one about 

 the summit of the declivity ; scaling dense, dai'k brown, except 

 the suture and inflexed margins, which are grey ; the boss-like 

 tubercle is entirely bare, the others only so at their apices, which 

 occasionally bear short depressed seta?. Legs with dense grey 

 scaling ; postei'ioi- tarsi nari-ow, the joints of about equal width, 

 2nd longer than 3rd and 1st than 2nd.

Long. 14, lat. 6 mm. 



Head convex, with close shallow punctures and dense brown 

 scaling, forehead with an elongate central fovea ; anteocular 

 furrows deep in their upper half, shallow below. Rostrum not 

 incised at base, as long as prothorax, slightly curved, dilated close 

 to apex. Upper surface convex at base, shallowly excavate 

 towards apex, finely and sparsely punctured, with a broad smooth 

 central line ; lateral sulci not wanting at base, upper pair broad 

 and deep, the lower obsolescent ; scrobes directed beneath base of 

 rostrum ; inferior basal furrow distinct. Antennce \f'\\h the scape 

 short, not nearly reaching eye ; the two basal joints of funicle 

 short, subequal. Prothorax longer than its width at base, which 

 is broader than the apex, sides distinctly angulated, broadest 

 before middle, dorsal anterior margin very convex, ocular lobes 

 strongly developed. Upper surface rather convex, with a broad 

 and deep central furrow containing no carina and flanked by a
