One .spet-imen from the Tpper Amazon ; 16 iniii. long. 



The anterior margin of the lahnim is stmight : the sides are lightly conve.x. The 

 la.st five joints of the antennae are lamellate, the mi<ldle lamella l)einc distinctly the 

 longest, though this .scartoly e.xceeds the one immediately preceding it l»y as much as 

 does the corresponding lamella of /'. fM'iifd/iliiflhis. The mandible.s each have three 

 distinct terminal teeth, of which the middle one is perhaps slightly nearer to the one 

 below it than to the one above it. The left anterior lower tooth is broader than the 

 right and is probably bidentate when unworn as in other species. The central tubercle 

 and parietal ritlges are small. The frontal ridge.s extend from the central tubercle at a 

 verv obtu.se angle to each other towards the outer tubercles, their cour.se being slightly 

 curved. The inner tubercles are distinct ami are nearer to the outer than to the central 

 tubercle. The outer tubercle.s. which are bluntly conical, are little larger than the inner: 

 they do not overhang the angles of the clypeus. which |)roject horiz<mtally in front of 

 them, terminating the lightly concave anterior marj.'in of the clyi>eus. The area between 

 the frontal ridges i> punctured in front of the inner tubercles, and smooth behind them. 



The pronotura is coarsely punctured laterally except (? always) in the neighbourho<Ml 

 of the scars. The sides and anterior margin of the jtronotum are .straight, with the angles 

 between them slightly prominent. The posterior m.irgin and angles are rounded ; the 

 Iatt«'r are densely covered beneath with long yellowish hair. The marginal groove is fine; 

 the minlian groove is almost complete. The posterior plate of the prosternum is broadly 

 trunc-ate liehind, Iwing little narrower behind than in front. There are a few indistinct 

 • ' on the scutellum. The me.sothoracic episterna are glos.sy above, and 



r ■ the anterior margin, below : they are punctured except in the posterior 



angles. The mesosternum is glos-sy. with deep pumfured .scars. The lateral areas of the 

 metastemum arc narrow throughout, rugose, ami very finely hairk' ; a row of puncture.s 

 extends along the inner side of the posterior intermediate areas. The alMloniinal 

 hterna are polishe«l except in the scars, which are matt. The elvtra are densely and
