Long. 21, lat. 7| mm. 



Head convex, with close but shallow punctuation and thin 

 scaling, which forms a transverse band on vertex and a line 

 running fi'om it above each eye, forehead with a small central 

 impression ; eyes very pi-ominent ; anteocular furrows deep. 

 Rostntm withovit a basal transverse incision, as long as head and 

 prothorax, moderately curved, strongly dilated at apex, the gensfr 

 being angidate externally. Upper surface plane in its median 

 half, with a deep rounded impi-ession at base and another near 

 apex, finely but distinctly punctiired except along the median line ; 

 upper lateral sulci almost obsolete, lower pair short but deep ; 

 scrobes dii'ected beneath base of rostrum ; inferior basal furrow 

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

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

 narrower than base, sides very little roixnded, broadest about 

 middle, anterior margin slightly convex, ocular lobes feebly 

 developed. Upper surface rather convex, with foiu' broad lines 

 of closely-set depressed tubercles, leaving a central furrow con- 

 taining a low carina and a broad smooth space on either side ; 

 these two spaces and a broad stripe on the side of prosternum 

 densely clothed with round white scales, the rest of the surface 

 bare. Elytra oblongo-ovate, shoulders sloping, sides subparallel 

 to beyond middle, apical processes short and rather blunt. Upper 

 surface convex, with regular rows of small shallow punctures j 

 interval 1 subcostate to beyond middle only ; interval 2 with only 

 a short apical subcristate row of small agglomerated tubercles \ 

 intervals 3, 5, and 7 with subcatenulate rows of small, often 

 duplicated, tubercles, that on interval 3 ceasing behind middle ;, 

 4 and 6 entirely plane ; colour black, with a broad stripe of dense 

 round white scales extending fi'om the outer half of interval 3 to 

 the inner half of interval 7, broken only by the bare tubercles on 

 interval 5, on the declivity this stripe extends further inwards 

 to interval 2 ; on the inflexed margin is another broad white 

 stripe, which does not quite reach the base and unites broadly 

 with the inner stripe at apex. Legs with sparse white scaling 

 foi'ming a denser patch near apex of femora ; posterior tarsi 

 broad, the 3i'd joint rather broader than the others, 2nd and 3rd 

 subequal in length, 1st longer.
