V. — Descriptions of new Pectinicorn Coleoptera. 

 By Charles 0. Waterhouse. 



Having recently been engaged in incorporating numerous 

 accessions to the Pectinicorn Coleoptera in the British 

 Museum, I have found several species which do not appear 

 to be described and which I have made the subject of 

 this paper, adding to them a most interesting species of the 

 genus Lucanus, kindly lent to me for description by Mr. A. 

 Fry.
