28 VARIETIES OF 



round, the outer one kidney-shaped, both having a brown margin ; the 

 third stigma is terminated on the inner margin by a pale mark, and 

 the subapical striga is pale, the apex of the wings being dark, the 

 cilia pale, spotted with brown ; the hind wings and abdomen ashy 

 coloured." 



y. var. euphrasies, St. (non Dup.). Apalevar. of rumicis is referred 

 by Mr. Stephens to the Continental euphrasice of Treitschke and Du- 

 ponchel. It is very different to that species, but is a well marked and 

 uncommon variety of rumicis. The ground colour of a pale yellowish 

 grey, with many black transverse lines, but no dark patches ; the 

 anterior stigma obsolete. A pale lunule is developed at the end of the 

 elbowed line, and the last striga is pale, wavy and continuous. I have 

 some fine specimens of this unusual pale form, which appear to agree 

 exactly with the description of Stephens' specimen, except that they 

 have the anterior stigma indistinct, not obsolete. My specimens were 

 taken in Cornwall, by Mr. F. Norgate of Brandon. The true euphrasice 

 is figured by Hiibner : the male, fig. 529; the female, fig. 615, the 

 latter under the name of cyparissice. 



Viminia, Chapman (Arsilonche, Ld.), albovenosa, Goze (yenosa, Bkh.). 



The type of this species, as its name indicates, has white nervures 

 which show distinctly on the pale wainscot ground colour. The 

 depth of the ground colour varies from pure silvery white to 

 deep (inclining to reddish) ochreous. A great deal of difference 

 exists in the development of the dark shades under the base 

 of, and above the outer half of the median nervure, and towards 

 the apex. Mr. Warren, of Cambridge, informs me that "the 

 specimens of the second (autumnal) brood are those which have the 

 dark dashes more prominently marked, and the fore wings sometimes 

 more thickly peppered." This form (with the dark shades clearly 

 developed) is figured by Hiibner (fig. 380) under the name of degener. 



a. var. centripuncta, H.-S. The anterior wings of this variety 

 have a black spot in the centre of each wing. The description Dr. 

 Staudinger gives is " alas anteriores puncto nigro." This form has, I 

 believe, at the present time only been recorded from Eussia, but some 

 of my specimens from Cambridge have this spot faintly indicated. I 

 should not be surprised to learn that this variety exists in some of our 

 collections. 



/3. var. ochracea, mihi. The ground colour of this variety is red- 

 dish ochreous, and the wing- rays pale ochreous instead of white, as in 

 the type. This variety occurs in both broods, some of the specimens 

 being almost devoid of the dark shades very strongly marked. I have 

 to thank Mr. W. Farren, of Cambridge, for a loan of fine series of this 

 variety. 



y. var. argentea, mihi. Ground colour silvery white, with no 

 trace of ochreous. My specimen, which is probably of the autumnal 

 brood, is much suffused with dark scales directly above and below the 

 median nervure, also along the costa, and less strongly along the inner 

 margin. Taken very rarely with the type.
