* Tliese two species although bracketed together, are sufficiently 

 distinct ; see elsewhere for distinguishing features. 



f In Or. tricolor, Fab., Or. consors, Boi., and Lo. contiyuus, n. sp., 

 the hinder apex is produced, rounded on the sides and truncate across 

 middle ; they would probably all have been referred to Loxopleurus 

 by Chapuis. 



X fn some specimens of Id. Tas^namca, Snd., and Pr. erudita, 

 Blackb., the margins are very distinctly crenulate, in others they 

 appear to be almost entire.
