Since writing the description of this genus I have received 

 specimens of " Optoma " i/niiii, Allib, a small Pellif/ allied to my 

 Jjiiphdcateri'S nanus. Previously yvtmi was only known to me 

 from descriptions, and, 1 had no idea from its association with 

 the Mm-opean OxftniKi (ii'ussitin, that it had any connection with 

 the small parallel sided Bornean species which 1 had named 

 L. numts. Thomson in his " Skandinaviens Coleojjtera" divided 

 Of<t(i7ii(i, or as it is generally called, Pcliis, into several genera. 

 I however, no genus appears ti> have been made for i/vtmi, as it is 

 not included in Thomson's admirable work, and therefore, as it 

 is closely allied to I.ophocateres ndiniSj I think that both these 

 insects should be associated in the same genus, ami i>laced vei-y
