30 THE ENTOMOLOGIST. 



gonodactyla, whilst our insect is without a name. I do not, 

 however, propose to invent a new one for it ; why, will 

 presently appear ; and for the present it will be convenient 

 to refer to it by the name it has borne so long in this country. 

 Among the zetterstedtl which I took in North Devon is one 

 example, which at the time I thought, from its greater size and 

 more pronounced markings, must be a distinct species. It was 

 figured as probably P. nemoralis, Entom. xiv., PL I., fig. 19, but 

 I subsequently determined it to be an exaggerated form of 

 zetterstedtl, believing, as I then did, that that insect was a distinct 

 species. Comparing this nemoralis -like specimen again with a 

 more varied series of P. nemoralis from the Continent, I cannot 

 now see that there is any material difterence between them. The 

 N. Devon insect is perhaps somewhat smaller in size and a little 

 paler in colour than nemoralis, but it agrees quite as well with 

 that species as it does with zetterstedtl, so that, unless it be 

 distinct from either (which I cannot suppose it is), it must be 

 considered an intermediate form, and as such it admirably serves 

 to connect our zetterstedti with continental nemoralis. The larva 

 of nemoralis is said to feed on Senecio memorensis ; so also, it is 

 stated, does that of zetterstedti ; therefore it may be that a form 

 of nemoralis occurs on the Continent similar to our zetterstedti. 

 and that it is this form which is the type of Zeller's species. 

 In the interests of synonymy and exact nomenclature, it will 

 of course be desirable to ascertain which of the insects we know 

 as zetterstedti and gonodactyla agrees best with Zeller's type of 

 zetterstedti. This at the moment, however, I cannot do, but hope 

 to be able to satisfy myself on the point before long ; any way, 

 the result of such enquiry cannot affect the conclusion at 

 which I have arrived touching the identity of our zetterstedti and 

 P. nemoralis, Zell. 



Amhlyptilia tceniadactyla. 



As stated by Mr. Leech (' Brit. Pyralides,' p. 54), my tcenia- 

 dactyla is a variety of our zetterstedti. Among a score of the 

 last-named insect, sent me by Mr. Purdy, of Folkestone, were 

 the form I had described and other intermediate forms. 



Platyptilia farfarella, Zell. Stett. Ent. Zeit., 1867, p. 334. 



Imago. — Expanse, 9-JO lines. Fore wing dingy brown, more or 

 less suffused with ochreous ; costal triangle, whitish submarginal line, and 

 fringes exactly as in gonodactyla, as also are the hind wings. 



Tills insect is probably only a form of P. gonodactyla, but 

 not, as I have supposed, peculiar to the second brood of that 

 species. I have several continental specimens, and they are 

 certainly smaller and darker than the usual form of gonodactyla, 

 bat, as a whole, they are not darker than some of \i\y gonodactyla, 

 or smaller than other specimens of that species in my collection.
