Head with three very broad and deep furrows which are con- tinued almost to the apex of the rostrum, strongly constricted behind the eyes, which are snbpedunculate, very prominent and curved backwards. Bosfnim as long as its width at the Fig. 42.—Bi/sclicrcs rugosus, Pasc. evidently narrowed from base to apex, deeply trisulcate and without any latei'al impression in front of the eye. Antennce with joint 1 of the f unicle distinctly larger than 2, the latter scarcely as long as broad, the remaining joints strongly transverse and set closely together. Prothorax variable in its proportions, its length being either greater than, equal to or less than its width at base, the sides straight and nearly parallel in the c?, slightly bisinuate and widening to the base in the $ , the basal margin bisinuate, its external angles acutely prounnent, the anterior margin deeply sinuate, its angles projecting; upper surface uneven, M'ith a deep central furrow bounded on each side by a shiny black carina, and two shallower interrupted furrows on either side. Elytra acumi- nate behind, separately rounded at the base, shortly and divergently mucronate at the apex, with broad sulci containing large, closelv set, subreticulate foveae, the intervals imrr
