88 LEPIDOPTERA. 



Species he pronounces to be the ochrearia of Hiibner — the 

 smaller species he named 'perochraria. 



" For many years in our ^ Tauschverein' both species have 

 been offered ; but under both names it was always only the 

 smaller species, perochraria^ which was sent, and never 

 ochraria. Also in the Silesian * Tauschverein/ where I 

 tried to obtain ochraria, I had not better success. Hence 

 it appears very clearly that most of the members of our 

 ' Tauschverein ' are ignorant of the distinctions between the 

 two species." 



I quote this to show how easily the two species are con- 

 fused even by collectors of some standing, for many young 

 entomologists have a habit of referring to the specimens in 

 the National Collection as if they were necessarily all cor- 

 rectly named. Now, in a genus like Acidalia or like 

 Eupithecia, unless the entire series of specimens have been 

 thoroughly overhauled by a competent Acidaliologist or 

 Eupitheciologist it would be very unsafe to place any confi- 

 dence in them. 



Acidalia strigaria, Hiibner (Fig. 1). 



Just in good time for this Annual paper, my kind friend 

 Mr. Bond brought me for inspection a couple ( $ and ? ) 

 of examples of an Acidalia, which we at once compared 

 with A. strigaria in my collection, received some years since 

 fiom Dr. Staudinger, and found to agree perfectly with that 

 species. These interesting specimens were captured this sea- 

 son, near Gravesencl, by Mr. D. T. Button. 



As strigaria will have to come in our lists next before 

 sylvestraria, Hb. (? Linne's immutata), the only British 

 species to which it bears the remotest affinity, though even 

 from that it is distinct indeed, a short sketch of its chief
