ERRATA. 



The generic name Ankistropliorus, used on pp. 140, 146, and 172, etc., 

 in Lord Walsingham's Revision of the genera Acrolophus and Anaphora, 

 is found to be preoccupied by the more correctly-spelt name Ancistrophora, 

 Schin. i in the order Diptera). Lord Walsingham is therefore desirous 

 to correel this error by substituting for Ankistrophorus the generic name 

 Homonymus, to be used throughout his paper, and in all references to 

 tins ^'i-nus. 



At p. 387 for Erebra read Erebia. 



At p. x of the Proceedings, for Euplthcccia read FAipithecia.
