764 REVISION Ot^ THE AMYCTERIDES, iv., 



SCLERORINUS BrOWNI, ll.Sp. 



(J. Large, robust, elongate, subparallel. Black, elytral tubercles 

 feebly diluted with red; moderately densely clothed with minute, 

 dingy-brown subsquamosity ; median vitta tawny-brown ; setse 

 dark. 



Head convex, almost in same plane above as rostrum, feebly 

 depressed in front at bases of the rostral foveas. Eyes suboval. 

 Rostrum little excavate, the external ridges very feebly convex 

 in profile, subparallel, continued up head for a short distance, 

 somewhat thickened internally about middle, sparsely setigero- 

 punctate; median carina distinct, narrower than the external 

 ridges, impunctate, separated from head by a punctiform depres- 

 sion, thence continued as a narrow, non-carinate, laivigate line; 

 sublateral sulci shallow, with deeper basal fovea3. Prothorax 

 (6 X 7 mm.) moderately widely dilated on the sides; apical margin 

 rounded, very feebly produced above, ocular lobes large; disc 

 convex from side to side, with a rather indistinct, subapical im- 

 pression, and a feeble impression at the latero-basal angle, median 

 impression hardly traceable; closely set with small, discrete, 

 somewhat depressed granules, smaller in the centre, and fewer 

 along the position of the sublateral vitta; ; sides with granules 

 obsolescent, except above. Elytra (15 x 8 mm.) robust, gently 

 rounded on the sides; base feebly emarginate, humeral angles 

 slightly noduliform; seriate punctures small, shallow, slightly 

 transverse, traceable with difficulty, the intrastrial granules small, 

 subobsolete; interstices tuberculate, sutural with small granules, 

 larger and distinct at base, becoming obsolete towards apex; 

 second interstice with four, moderately large, slightly elongate, 

 somewhat depressed tubercles, about middle; third interstices ap- 

 pi-oximated on the declivity, with a continuous row of about 

 twenty-live, small, granuliform tubercles, never becoming conical, 

 extending from base to apex, smaller than those on second inter- 

 stice; fourth without tubercles; fifth with a row of twenty-five, 

 similar to third; sixth with a row of ten, slightly larger, and 

 more separated, than those of third and fifth, but smaller than 

 those of second, not extending to base. Sides with tubercles
