NOTES ON THE VARIATION OF PERONEA CRISTANA, FAB. 35 
Xylophasia sublustris, Ksp.—Very local at Favour Royal (K.). 
Xylophasia monoglypha, Hufn. —-Abundant everywhere, vary- 
ing from a pale form to vars. infuscata, White, and ethops, Tutt ; 
the latter not uncommon at Lough Fea and also near Favour 
Royal (K.). 
Xylophasia hepatica, L.—Kane records this species as very 
local at Altadiawan and Favour Royal. 
* Aporophyla nigra, Haw.—Rare at sugar, Killymoon. 
Miselia oxyacanthe, L..—Abundant at sugar and ivy bloom ; 
one ab. capucina, Mill., near Killymoon ; a dark form approach- 
ing this at Favour Royal (K.). 
Agriopis aprilina, L.—Rare in the county (K.); a single 
example at sugar near Lissan.

NOTES ON THE VARIATION OF PERONEA CRISTANA, 
FAB., WITH DESCRIPTIONS OF SIX NEW FORMS, 
AND THE REASONS FOR SINKING THE NAMES 
AT PRESENT IN USE OF SIX OTHERS. 
By W. G. SHeupon, F.Z.S., F.E.S. 
(Continued from p. 16.) 
Ab. ulotana, Clark. After very careful study I am convinced 
that this aberration is identical with ab. sericana, Hub. 
Clark describes this (loc. cit., p. 291), ‘‘ anterior wings dark 
slate-colour, with a bright red streak which proceeds from the base 
to the large button, which is also red’’; and of ab. sericana, Hub., 
he says, “‘ fore wings of a purplish grey, but with a bright orange 
median longitudinal line from base to beyond the middle of wing, 
edged above with a darker line running up to apex.” 
To the ‘‘ purplish-grey”’ colour of sericana one must give a 
certain latitude, for, as is well known, Hubner’s figures vary a good 
deal, and in the six copies of his work I have been able to consult, 
no two give the ground-colour of this figure exactly the same ; in 
one at least it is practically identical with Clark’s type of wlotana, 
which, moreover, has the front of the superiors ‘‘ edged with a 
darker line running up to the apex,” described by Clark as charac- 
teristic of sericana. By far the most striking character of ulotana 
is the “ bright red streak which proceeds from the base to the 
button,” and this is identical in both forms; the name wlotana, 
Clark (1901), should therefore sink in favour of the much older 
one of sericana, Hub. (1796). 
Ab. nigropunctana, Clark, comes near to ab. fulvostriana, 
Desvignes. Clark says “it is easy to distinguish it from albipunc- 
tana, Stephs., and ochreapunctana, Clark, because it has an almost 
black button and the others have light ones,’’ but he does not
