 Tliis sj)ecies resembles the preceding in the sculpture of its 

 rostrum ; the i)rothorax is ahnost similar, but is a little more 

 <lilated and rounded near the front, so that the sides appear 

 slightly sinuate ; the sterna and ventral segments are similar; 

 but the general form and the elytral sculpture are so diti'erent 

 that I feel compelled to ti'eat it as more than a variety. In 

 hiordmatus the elytra are very parallel, and are at their widest 

 distinctly in front of the middle; while in raucus they are 

 detudedly more oval, and are at their widest ai the middle in the 

 male, and slightly behind the middle in the female. As regards 

 the sculpture of the elytra, in hiordmatus the non tuberculate 

 interstices are distinctly traceable as line longitudinal lines, the 

 spaces between them being somewhat feebly cancellate-punc- 

 tulate, owing to tlie presence of series of transverse lines 

 similar to those which form the interstices ; all this sculpture, 

 however, having a feeble and blurred appearance. In raiicics no 

 longitudinal interstices are distinctly marked, except the three 

 tuberculate ones ; the spaces between those three (and between 

 the suture and the inner one) being occupied by strong irregular 

 transverse lines, which in places run right across from the suture 

 to the middle tuberculate carina, passing in a zigzag fashion 

 between the tubercles of the first row; here and there two of 

 these transverse lines are connected by a short oblique or longit- 

 udinal line, but not by anything like a continuous longitudinal 

 line. 'Che huineral angles are even sharper than in hiordinatus, 

 and in none of the examples of either sex before me of raiicus do 

 the tubercles of the tii'st row coalesce in front into anything like 

 a continuous carina
