As it was impossible to apply the name of murinipennella to any 

 of these species without doing violence either to what had been 

 written previously about the perfect insect, or about the larva, I re- 

 ferred the matter to Mr. Stainton, and have been guided by his 

 decision. After most kindly examining all my material, he wrote 

 about this insect, " This is my idea about murinipennella, the most 

 distinctly streaked of the group ;" and he added, " I had already more 

 than suspected the case figured in Nat. Hist. Tin. as that of murini- 

 pennella did not really belong to the moth figured." 



C. r^SPITITIELLA. 



Exp. al., 5 — 5| lin. Fore-wings shining grey, or ochreous-grej, unstreaked ; 

 eosta oonspicuouslj white, fading gradually into the greyish -ochreous fringe at the 

 apex. Antennae annulated with grey on the inner face, the outer face and tip 

 entirely white. A paler and more ochreous form occurs, in which a few short and 

 dark, but obscure, dashes run into the apical half of the eosta, conveying the im- 

 pression that a part of the grey element had crystalized out, as it were, along these 

 lines, and had left the rest of the wing paler and more ochreous. In the type, the 

 grey uniformly-coloured fore-wings and the clear white eosta give it some resemblance 

 to adjunctella, but besides being darker, the latter has the wings broader and browner, 

 and the antennse completely annulated. 



It is usually fully out by the middle of June, and lingers on in 

 greatly reduced numbers till about the middle of July. It is, perhaps, 

 the most abundant and widely distributed of the species. With me 

 it is almost exclusively an inhabitant of wettish woods, for the reason 

 that its favourite food here, namely, J", conglomeratus and effiisus, are 

 only found in any quantity in such places, but on the western side of 

 the county I meet with it on open moorland about 1800 feet or more 

 above the sea, where it flies among J. conglomeratus and squarrosus. 

 At one time I could scarcely believe that this squarrosus insect could 

 be the same species, but except that the few specimens I have reared 

 of it are a little darker than the type, I can discover no other differ- 

 ence, and as neither the caudal apparatus nor the larvae and their cases 

 lend any countenance to its distinctness, the idea had to be relinquished. 

 I may add, that through the kindness of Mr. Bankes I have been able 

 to examine a long series bred by that gentleman from the same plant, 

 and his specimens, too, seem also a little darker than usual, whilst 

 amongst them is not a single instance of the pale ochreous form. 



Larva, yellowish-brown, or mahogany coloured. Head black. Plates black or 

 blackish. Both pair of dorsal sub-plates present on 3rd, but no trace of either on 

 4th. The spiracular plate on 4th is also unusually small, being barely one-fourth 

 the size of the one on 2nd. There is frequently a small, dull, blackish spot on the
