possesses a combination of features essentially its own. Its 

 most extraordinary character, however, is certainly the construc- 

 tion of its rostrum, which has the appearance of being a separate 

 piece, as it were turned with a lathe [a circumstance which has 

 suggested its generic name], and implanted into the fore portion 

 of the head ; and it is on account of its seeming thus separate, 

 and of its being rounded off at its base, that it looks, at first 

 sight, as though it were suddenly constricted at its point of con- 

 tact with the head.

T. dull brownish-piceous and nearly opake, densely beset all 

 over with very large and exceedingly depressed scale-like granules 

 (of much the same character as those of the Tarphii). Rostrum 

 rufo-ferruginous and more shining than the rest of the surface, 

 keeled down the centre, and roughly (but sparingly and irregu- 

 larly) punctured on either side. Prothorax subovate and rather 

 acuminated anteriorly, and quite free from any appearance of 

 pile. Elytra subelliptic, most lightly (and not very regularly) 

 striated, and (beneath the microscope) with longitudinal series 

 of very short, most minute, distant, and decumbent paler hairs. 

 Body beneath densely scabrous, but scarcely punctured. An- 

 tenna rufo-testaceous. Legs slightly setose, but hardly paler than 

 the rest of the surface. 



Captured by myself, adhering to the underside of the trunk 

 of a felled cherry-tree, which was lying on the damp ground, at 

 the bottom of the Curral das Freiras, during my encampment 

 there, with the Rev. R. T. Lowe, on the 9th of December 1858.
