186 THE ENTOMOLOGIST. 
and 54). Fritsche’s description extends ie sole lustre, sug- 
gestive of C. aurorina. heldreichi, to all the wings, and he com- — 
pares it to that of Apatura iris and A. iole. As we all know, 
typical ¢ Edusa are often suffused with a rosy glow, which may 
or may not be transient, if, as 1 suspect, the glow is apparent in 
all freshly emerged individuals of the gen. est. Mr. Fitch 
(op. cit.) confirms the occurrence of ab. Micans in this country 
in 1877. 
(z) Ab. 2 Divisa, Verity. Marginal band hind wings com- 
plete; sharply divided by series of light markings which together 
form a discontinuous line. 3 
(aa) Ab. 2 Semidivisa, Rocci (1920). With the same 
characters as Divisa on the hind wings. . 
(bb) Ab. 2 Internodimidiata, Verity. The lemon blotches 
confined to the inner margin of the band on the hind wings. 
(cc) Ab. 2 Semiobsoleta, Rocci (1920). Blotches on the 
marginal band of the hind wings completely wanting. 
(dd) Ab. 2 Seriata, Rocei (1920). A form of the type having 
the series of the small ferruginous spots on the under side of the 
hind wings, usually absent, complete. The series is normally 
complete in gen. vern. and gen. autumn. 
(ee) Ab. Deannulata, Rocei (1920). The small silver spot 
above the discoidal spot on the under-side hind-wings absent. 
The double silvered spots detached on the ground-colour. 
(ff) Ab. Bimaculata, Verity. As in (ee), but on the upper 
side of the hind wings. 
(99) Ab. digra, Verity. Underside of the fore wings irregu- 
larly spotted with pale black. On the upper side also in the 
discal area. A pathological example. 
(pD) Chiefly Variation of Size. 
(hh) Ab. Minor, Failla (1889) (= ? var. Pyrenaica, Gr. Gr.). 
I have already discussed this so-called aberration in its relation 
to Vernalis. A small form is constant in both sexes in the gen. 
vern. of the South of France, and is not uncommon in November 
emergences when they occur in Britain. Fitch figures in colour 
(loc. cit.) a female of what he calls the third brood, and gives in 
the text a woodcut of a male with much contracted hind wings. 
Unless ab. Minor is to be applied to all diminutive examples of — 
whatever generation—and I suppose the author so intended—it 
is somewhat difficult to separate this form from the following : 
(w) Var. Pyrenaica, Gr. Gr. (‘ Hore Soc. Russ.,’ 1893, p. 383). 
This is described as follows: 
‘“‘Varietas fere duplo minor. Alis ¢ pallidioribus, posticis 
in disco cinereo-sparsis ; 9? alis anticis ex flavido-rutilis, posticis 
griseis, leviter aurantiaco-pulverulentis ; maculis flavescentibus 
in limbo externo positis subnullis. Volat in alpibus Pyrenaicis.” — 
If identical, therefore, with ab. Minor, Pyrenaica falls to it.
