obsolete. Rostrum not incised at base, about as long as head and 

 prothorax, comparatively slender and only slightly curved. Upper 

 surface convex in the basal two-thirds, broadly excavate near 

 apex, densely covered with whitish scaling except on a broad 

 smooth central carina and two narrow ones on either side ; lateral 

 sulci not meeting at base, subequal in length, the upper pair 

 broader ; scrobes directed to beneath base of rosti-um ; inferior 

 basal furrow distinct. Aniennce with thin pale scaling ; scape not 

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

 a little longer than its width at base, which is broader than apex, 

 sides obtusely angulated, broadest about middle, dorsal anterior 

 margin distinctly convex, ocular lobes strongly developed. Upper 

 surface convex, with a broad and very deep central furrow (without 

 any carina) flanked Ijy a row of small closely-set rounded tubercles, 

 with a similar incomplete row adjoining it ; beyond this a broad 

 smooth space, followed by a single regular row of small tubercles 

 near the margin, with another similar row a little below it ; the 

 central tubercles of this latter are a little larger than the others 

 and thus cause the lateral angulation ; apices of tubercles bare, 

 each with a depressed dark seta, interstices with dense sandy-grey 

 scaling, that on sides of presternum pure white. Elytra elongato- 

 ovate, shoulders sloping, sides slightly rounded, broadest about 

 middle, apical processes very long and sharp. Upper surface 

 convex, with regular rows of shallow punctures ; intervals 1,2, 4, 

 and 6 devoid of tubercles ; 3 and 7 each with a complete row of 

 long sharply conical tubercles, those on the basal half of the furrow 

 much smaller than the others; interval 5 with a very large 

 rounded boss-like tubercle at base, followed by two (sometimes 

 three) long conical distant tubercles ; tubercles bare, except on 

 their anterior faces which are squamose, each with a single short 

 suberect black seta, except the boss-like tubercle which has two ; 

 scaling dense, circular, uniform greyish white. Legs with dense 

 white scaling, the tibia? mottled with bare spots ; posterior tarsi 

 narrow, joints of the same width, 1st longer than 2nd and 2nd 

 than 3rd.

Head convex, obscurely punctured and covered with large brown 

 scales, except a short smooth line on forehead, which contains a 

 small puncture ; a narrow ring of white scales round each eye ; 

 anteocular furrows pi'actically obsolete. Rostrum not incised at 

 base, as long as head and prothorax, very little curved. Upper 

 surface rather convex at base, but excavate towards apex, punc- 

 tured and covered with brown scales except along a broad smooth 

 central line ; lateral sulci not meeting at base, filled with large 

 white scales, upper pair very broad and deep, the lower narrow
