Black, bare and sliining, with the following markings formed of 

 pinkish-white scales : a broad stripe on eacli side of the rostrum, 

 extending right along the thorax and on to the base of the elytra ; 

 a large transverse humeral patch, sometimes broken up into a 

 number of small spots ; an irregular, usually much interrupted, 

 transverse baud about the middle, extending from the third sulcus 

 to the margin ; an irregular stripe along the posterior part of the 

 suture, and a small transverse patch on each side near the apex; 

 underparts entirely of the same colour. 



Head with three very broad and deep furrows which are con-

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 imrrow and undulating, the
