Pupa — The pupa of this species is also described by Mr. South. He 

 writes as follows : — " Colour dingy green, a broad dorsal stripe obscure 

 red-brown ; dorsal hairs and warts as in the larva ; sometimes the 

 whole of the dorsal area is suffused with red-brown. In this case, the 

 wing-cases are pale green, and the antenna-cases either brownish- 

 green or red-brown ; fastened by anal segment to some portion of food 

 plant, often to a leaf or stem of the withered top. July " 

 (" Entomologist," Vol. XVI., p.26). Figures of all stages of this species — ■ 

 larva, pupa and imago, together with the food plant, are given in " The 

 Entomologist," Feb., 1883. The figure of the imago is very poor indeed. 



Time of Appearance — The imago rarely appears until well into 

 July. I remember this species and tetradactyla on one occasion being 

 very abundant during the first week in August, when Mr. Ovenden and 

 myself captured a large number. There is no doubt that during the 

 last week in July and the first week in August the moth is most 

 frequently taken. 



Habitat — The species appears to be almost entirely confined to chalk 

 downs, where its food plant occasionally grows abundantly. In such 

 localities it maybe sometimes taken in plenty. I have found it commonly in 

 the daytime at Cuxton and in the Warren at Folkestone, but it flies much 

 more freely at dusk, and at that time sometimes abounds, but it is a very 

 local species, and must be looked upon in reality as the rarest member of 

 the genus in Britain, although more widely distributed than some of them. 

 Stainton gives as localities : — " Bristol, Lewes and Mickleham." I have 

 also taken it sparingly near Kingsdown. Wocke gives a rather long 

 list of localities, which, however, are chiefly situated in the Southern 

 parts of Europe, our own Southern counties being about its northernmost 

 limit. These are " Southern Germany, Switzerland, England, France, 

 Italy, Andalusia, Greece, Sarepta, Bulgaria and Bithynia." 

 (" Catalog.," p. 345). 



Aciptilia migadactyla, Haw., {spilodactyla, Curt). — This species is 

 very closely allied indeed to galactodactyla, but there is much more 

 fuscous shading in this, and the species, therefore, has a very suffused 

 appearance compared with galactodactyla. 



Synonymy — Migadactyla, Haw., ' Lep. Brit.,' p. 478; Tutt, ' Ent. 

 Record,' I., p. 93. Spilodactyla, Curt., ' Brit. Ent.,' IV., 161 ; Stphs., 

 * 111.,' IV., 371 ; Dup., XL, 314, 9; Zell., 4 Linn. Ent. Zeit.,' VI., 391 ; 

 H.-S. 25, V., p. 383. Obsoletus, Zell., ' Isis,' 1841, 859 ; Ev., ' Faun. Vol. 

 Ural.,' 609. This species was named obsoletus by Zeller in the " Isis," 

 but afterwards corrected by that author in the " Linnsea Entomologica." 

 There is very little doubt that the correct name of this species is 

 migadactyla, Haw. In 1890, I wrote with regard to the synonymy of 

 this species : — " Wocke (as I have just pointed out) not only refers 

 Haworth's pallidactyla to Hiibner's ochrodactyla, but, more mysterious
