is that while qtiailraiia alnioist iuvariahly shows a distinct white line, 

 jnst inside the dark line at the base of the cilia, extending downwards 

 from the actual apex of the fore-wing to about the middle of the 

 ternieu, no such line is to be seen in its ally. 



The Avieniore examples of ericetana, H.-S., show only a limited 

 amount of variation in the matter of colour : none of them differ 

 greatly from Herrich-Schaft'er's description (loc. cit.) and figiu'e 

 (f. 136), though none aj)pear to be precisely typical. I should 

 describe their groiuid-colour as silvery whitish drab, shoAving, in some 

 individuals, a partial purplish-red tinge, which varies in intensity, 

 tends to spread to parts of the cilia of all the wings and to the upper 

 half of the basal patch, and occasionally aifects strongly even the 

 head and thorax. The principal markings are bright russet-brown, 

 often more or less suffused, in parts, with blackish. In his table of 

 species of the Tortricina, in Schinet. Deutsch. u. d. Schweiz, von 

 Heinemann gives (p. 29) the ground-colour as " shining, violet-reddish 

 white or light violet-grey," which proves that he was acquainted with 

 a form almost, if not cjuite, identical with one included in my own 

 description, as well as with the typical one described by Herrich- 

 Schiitt'er. Differing widely from these, Frey's eight exponents, hailing 

 from Frankfort ((^, ? ), Breslau ((^), the Griarner Alps ((5^), the 



Engadine (S), Zermatt (cJ), and ?"''?'' " ( c? ' ? )' I'epresent a 



very much darker and more unicolorous form. The ground-colour of 

 the males is of a dull grey — exactly similar to that of Frey's specimens 

 of E. fmcfifasciana, which only differ from my English ones in their 

 much larger size — and the markings are merely of a darker shade of 

 grey, somewhat mixed Avitli brown. Frey's two female examples of 

 ericetana show the same relative difference from the males as are seen 

 in the Aviemore form. They have a more mottled appearance, owing 

 to the ground-colour being a little paler, and to the markings, which 

 are rather stronger in colour and more clearly defined than in the 

 males, showing up much more distinctly against it. In both sexes, 

 however, the contrast between the ground-colour and the markings is 

 immeasurably greater in the typical form, and in those nearly 

 approaching it, than in the varietal one in the Frey collection. 



In Verh. Zool. G-es. Wien, 1872, pp. 733-734, Staudinger brought 

 forward Steganoptycha languentana as a species new to science, and in 



* From a comparison of many labels written by Frey, it is clear that lie here intended to 

 express doubt about the locality of these two individuals, and not about thoir identity or date 

 of capture, &c. It may, therefore, be of interest to point out that Bi-emgartcn is definitely 

 recorded as a station for the species under notice, by Frey himself, in Lep. Schweiz, 326 (1880).
