A few words of explanation must be given as to the changes in 

 this list of British plumes since that published in 1869. 



The Oxyptilus caught near Thetfordf and in other parts of our 

 Eastern counties is changed from Icetus to distans. There is no doubt 

 about this. Prof. Zeller first pointed out the mistake to me several 

 years ago : Icetus is a smaller insect, and, indeed, very different. 



Oxyptilus pilosellcs is the "Mickleham plume ;" no native speci- 

 men of O. Meracii has ever come under my notice. 



Mr, Barrett, it seems to me, satisfactorily proved Mimceseoptilul 

 aridus to be only a variety of 31. serotinus. 31. Hodgkinsoni, it is 

 sadly to be feared, is only a form of zophodactylus. 



31. pin gio dactylus deserves investigation, the small bright-looking 

 form of the Lake district (scabioscB, Gregson) is at first sight very 

 different from the German specimens, which have a much larger blotch 

 on the costa, but the " plagium " is distinct in both. 



Unfortunately, no new JPterophorus has been added to the list.

* I am afraid that the names Leioptilus grandit, Fitch, (Edematophorus cineraceus, Fitch, and 

 Trichoptilus ochrodactylus, Fitch, must be changed, since we have Platyptilia ochrodactyla, Plat, 

 grandis, and Aciptilia cinerascens ; in making out this list I am much indebted to the kindness 

 of Lord Walsingham. 



t Oxyptilus distans was first taken in England, near Thetford, by Lord Walsingham.
