 Matthews, Ent. Mo. Mag. vol. ii, p. 242. 

 inquilinum, Erichson. 



Ptilium foveolatum, Allibert, loc. cit. ; Rev. A. Mat- 

 thews, Ent. Mo. Mag. vol. ii, p. 242. 

 excavatum, Erichson. 

 Mr. Matthews, for the reasons above stated, considers these 

 changes in nomenclature should be made. 



Ptilium trisulcatum, Aube. 

 Mr. Crotch (Ent. 32, p. 120) deposes Weber's minutisH- 

 mum, as that name had been previously used by Linna?us, 

 and followed by Marsham, for an Acrotrichis (the prior 

 generic name adopted b}^ Motschulsky and Wollaston for the 

 well known Truhopteryx). 



Corticaria ferruginea. Marsh , nee Gyll. 

 elongata, Gyll. 

 Mr. Crotch (loc. cit.) states that Marsham's name clearly 

 applies to the commoner of our two species ; hence the 

 necessity for this and the following change. 



Corticaria rufula, Zett. 



ferruginea, Gyll., nee Marsh.
