maxillae are furnished with a thick brush at the apex much of the 

 rough appearance of a minute bundle of coir. The inner edge of 

 the lobes of the mentum is very broadly cut away. The ligula 

 appears, what I understand it to be from Lacordaire's description, 

 coriaceous, of middling size, of the shape of an oblong square, de- 

 pressed in front and at the sides, set in its membranous and ample 

 paraglossse as in a broad frame ; the whole obliquely truncated at 

 the anterior angles, and ciliated along the anterior margin. The 

 palpi can hardly be said to be truncated at the apex of the 4th joint, 

 finishing off rather like an acorn. The remaining parts of the mouth 

 and the head in general are of typical construction. The thorax 

 is strongly transverse, subquadratic at the base and firmly applied to 

 the elytra but not quite as large. The latter being also subquadra- 

 tic at the base, the place of the juncture of these two parts of the 

 body presents, upon close inspection, rather a peculiar appearance. 

 The thorax is gently narrowed towards the apex, the anterior part 

 is deeply emarginated in the shape of a crescent, the posterior part 

 slightly so at the middle, the emargination being long, shallow and 

 nearly rectangular, its external corners fitting into two deep notches 

 in the base of the elytra. The anterior angles are rather acuminat- 

 ed. The back is elevated and divided by a longitudinal line, it has 

 2 impressions at the base and is finely sulcated just in front of the 

 scutellum. The elytra are furrowed and irregularly impressed with 

 deep punctures along the 9th ridge, they are slightly dehiscent at the 

 apex. The legs of the male are of the following description : strong 

 coxae, trochanters and femora simple, the latter slightly setose, the 

 anterior tibiae strongly dilated towards the apex and costated, strong- 

 ly spinoso-dentate at the outer edge, with a strong, blunt spur at 

 the notch and another at the apex, the latter place, moreover, fur- 

 nished with spines. The intermediate and posterior tibiae with 3 

 rows of spines along the outer and 2 rows of strong bristles at the 

 inner side — all inserted on ridges, strongly 2-calcarated at the apex, 

 the inner spur longer than the outer one. These apical spurs of 

 the tibioe are in all the legs slightly compressed and serrated on the 2 

 narrow sides. The anterior tarsi have joints 1-4 slightly dilated, the 

 apex of the first and the 2nd and 3rd being at the same time furnished 

 each with 2 small white brushes below fenced in by spines. Joint 1 is
