NOTES ON THE VARIATION OF PERONEA CRISTANA, FAB. 37 
Exactly as semiustana, Curtis, but with pure white vitta, 
button, subsiding tufts, head and thorax. The specimens are all 
without data, but Webb says: ‘‘Several specimens have been 
taken in the New Forest.” Mr. South has an example of this 
form, which also came from the New Forest. 
Ab. webbiana, n. ab. ‘This form is similar to the last, with 
the exception that the vitta, button, subsidiary tufts, head, palpi 
and thorax are cream-coloured instead of white, and the ground 
colour of the superiors is darker. There are half a dozen 
examples in the collection, two from Folkestone (Purdey), one 
Epping Forest, no doubt from Clark, and three without data. 
I believe this is not an uncommon aberration at Folkestone, and 
I have obtained two this year from the New Forest. The form 
is of course named after Sydney Webb. 
Ab. fulvana, n. ab. Exactly as desfontainana, Fab., but with 
only a trace of a button. The examples, nine in number, 
were labelled by Webb ab. sericana, Hub. They are old specimens, 
set on white pins, without data, except that one is labelled 
‘** Sheppard’s sale” and another ‘‘ Bond Collection’; the form 
is a not uncommon. one in old collections, but I do not know 
of any modern examples, and presume it came from a locality 
that no longer produces cristana. 
Ab. ustulana, n. ab. This form is the one that at present is 
usually, but erroneously considered to be ab. provittana, Dsvgs. 
It is exactly as ab. semiustana, Curtis, but has a cream-coloured 
vitta, head, palpi and thorax; it is a well-known and striking 
form, not uncommon in the New Forest, from which | have a 
series of fifteen specimens. ‘There were four in the Webb 
Collection, three of which were labelled ‘‘ Bond Colln.”’; the other 
was unlabelled. 
Webb states (loc. cit.), vol. xlii, p. 266, “The old students 
of cristana regarded a ‘similarly colored’ (to proxanthovittana, 
Clark) ‘ brown tufted insect’ as vanthovittana, Desvignes. 
As the true xanthovittana, Desvignes, is without, or has only 
a small button, it follows that the form quoted by Webb is at 
present without a name, for clearly he refers to a form with a 
button of average size; his suggestion (loc. cit.) that the name 
proxanthovittana, Clark, should be transferred to it being homony- 
mous is invalid in accordance with the Jaws governing nomen- 
clature. I therefore give it the name fulvopunctana, n. ab., and 
describe it thus. 
Superiors reddish brown, with the bases, costal blotch, and 
some smaller areas of a slightly darker brown colour, giving the 
whole wing a somewhat mottled appearance ; the button is bright 
red-brown ; the head, palpi and thorax are a dark cream colour 
with red-brown scales intermixed ; the vitta is a rich vellow. 
There are sixteen examples in the series; all old specimens, 
three of which date before 1850. All are without data with the
