There are several examples of this large and well-marked 

 Microxylohius amongst the collectanea of Mr. Melliss ; and as 

 it was likewise captm-ed by Mr. Bewicke, in 1860, dm-ing the 

 few hours which he passed in the higher districts of St. Helena, 

 we may expect it to be tolerably common in the more ele- 

 vated regions of that island. It is easily recognized by its 

 large size, robust body, blackened hue, and thick limbs, by its 

 densely and deeply punctured, though but slightly shining, 

 surface (which, however, is less opaque than in the lacertosus 

 and vestitus), by its thickened rostrum (particularly in the 

 male sex), by its ample, laterally rounded prothorax, and by 

 its rugulose elytra. Like the remainder of the Microxylohii 

 enumerated below, its surface is free from ail traces of even 

 minute pubescence.

 dispositis) ; antennis rufo-piceis, basi clarioribus ; pedibus nigro-

It is somewhat singular that the present species is not re- 

 presented amongst the numerous specimens of Microxylohius 

 which have been captured by Mr. Melliss ; so that my dia- 

 gnosis has simply been drawn out, and corrected, from the 

 original pair which were captured by the late Mr. Bewicke at 

 St. Helena in 1860. In its brassy hue and shining surface it 

 recedes from the preceding members of the group, and assimi- 

 lates those which follow ; but the fact of its tibiae being simj)le 

 will at once separate it from the whole of the latter except the
