SCLERORINUS BLACKBURNI, n. Sp. 



(3 . Elongate, subparaliel, strongly tuberculate. Black; 

 clothing dense, rich-brown, on head forming median and sub- 

 lateral vittae : a brownish patch on either side between 

 vittae ; whitish on prothorax forming feeble sublateral 

 vittae and faintly indicated in middle line; elytra with inner- 

 surfaces of tubercles clothed with white ; sides of prothorax 

 and elytra with white. Beneath with a dense tomentose vitta 

 of a rich ruddy-brown colour. Setae black. 



Head strongly convex, the upper rostral surface not in 

 same plane as head, forehead flattened in front, external 

 rostral ridges extending back with a slight change of direction 

 on to the head. Rostrum broad, evenly though not deeply 

 excavate, external ridges slightly divergent posteriorly, median 

 carina narrow, distinctly raised, not extending upon head, 

 sublateral sulci broad, shallow, with smaller deeper foveiform 

 depressions at base. Eyes subrotundate. Prothorax (6 x 7"5 

 mm.) dilatate, subangulate on sides anterior' to middle, post- 

 ocular sinuation of apical margin moderately strong but lobes 

 not marked ; disc with evident transverse subapical impression, 

 median line free from tubercles, sublateral lines irregularly 

 impressed, free from tubercles ; elsewhere with strong irregular 

 somewhat depressed tubercles, rounded or slightly transverse. 

 Sides with granules decreasing in size from above down and 

 not continued to coxae. Elytra (15 x 8 mm.) elongate, little 

 widened, apex almost subtruncate, with a strong granulate 

 flange; base feebly arcuate, humeri with single, outwardly 

 directed, tubercle. Disc with rows of small shallow foveiform 

 punctures obscured by clothing, each subtended by a small, 

 setigerous granule; interstices tuberculate, sutural with a row 

 of fine granules larger at base ; second with four large spinose 

 tubercles, black, spaced out and uniformly placed on the two 

 sides ; third with a continuous row of strong spinose tubercles, 

 upwardly, backwardly somewhat outwardly directed, nine on 

 left, twelve on right in type ; fourth without tubercles ; fifth 

 with humeral tubercle only, followed by a small granule, 

 thence interstice only traceable by a row of setae; sixth with 

 a continuous row of large outwardly-directed tubercles, ten in 

 number. Sides with rows of rounded granules or tubercles 

 diminishing in size in successive rows. Under-surface with deep 

 groove on either side of vitta on first and second segments, the
