1888.] 3 



For a time I was certainly puzzled by the very marked differences, 

 as given above, in the shape and composition of the cases of the two 

 species ; but on hearing from Mr. Bond that he could give no really 

 satisfactory account of the cases in his collection, which, it must be 

 remembered, are the only so-called Frischella cases in existence, I was 

 naturally led to think that there had probably been some mistake 

 made about them, or some accidental transposition of cases, and that 

 these conspicuella-like cases might, perhaps, after all, be veritable cases 

 of C. conspicuella. 



To sum up the whole matter then, and bearing in mind that Mr. 

 Dale's original specimens of C. trifolii (= Frischella) are undoubtedly 

 the species now known as G. melilotella, I think it has been shown 



1. that the imagines of these two (?) species are in every respect 



identical ; 



2. that the recorded localities for the insects are the same ; 



3. that G. Frischella used, previous to 1860, to frequent " rather 



plentifully " the flowers of " the trefoil ;" while G. melilotella has, 



ever since 1860, when it first received its name, been found in 



some plenty attached to the flowers of the melilot, which was 



formerly known and classed as a trefoil. 



Against all this we have the fact that the two cases in Mr. Bond's 

 cabinet, which have long been supposed to be those of G. Frischella, 

 have no resemblance whatever to the rather peculiar cases of G. meli- 

 lotella. 



After reading Mr. Bond's own account of his cases, and carefully 

 weighing the pros and cons, the only reasonable conclusion open to us 

 seems to be that we have here an instance of one and the same species 

 doing duty, for more than a quarter of a century, for two distinct 

 species under different names. The mistake may, I think, be attributed 

 entirely to the fact that the identity of Mr. Bond's cases has, up till 

 now, never been called in question ; and we can only regret that so 

 large an amount of time and energy has been spent in vain by so 

 many Micro-Lepidopterists in the attempt to re-discover in its original 

 localities the long-lost G. Frischella— an attempt which has almost 

 invariably ended (and no wonder!) in the capture of the more 

 recently described G. melilotella. 



A word must now be added to explain the omission of any 

 reference to foreign authors in general, and Yon Heinemann's 

 " Schmetterlinge Deutschlands und der Schweiz " in particular. On 

 referring to the account given in that work (Band ii, Heft ii, s. 519,
