158 THE ENTOMOLOGIST. 
of the superiors, having only this elegant lunule to relieve it, 
makes ab. romanana one of the most beautiful of all the forms 
of this exquisite species. It is extremely well figured by Hubner, 
fig. 88. As his book is so rare and costly I have figured an 
example. 
So far as I am aware ab. romanana is an extremely rare 
form in Britain. I have three examples which came from the 
New Forest. There is also one in the National British Collec- 
tion, but I do not know of any others. 
Ab. griseana, n. ab. 
I give this name to a form which is exactly similar to the 
type, but it has the ground-colour of the superiors, which in the 
type is green, light slate-coloured grey. 
I have only seen two examples of this form, both of which 
are in the collection of Mr. South; the type is labelled 
**98.8.1914”; both are from the New Forest. — 
A figure is not given of this aberration, as the point of 
differentiation from the typical literana, L., i.e. the grey ground- 
colour of the superiors, does not show by the half-tone process. 
Ab. fulvoliterana, n.ab. (Plate I, fig. 4.) 
Synonomy.—Hubn., Tort., fig. 91, 1797 (literana) ; Hubn., 
Verz., p. 886, No. 3750, 1826 (erugana). 
The only author who seems to have dealt with this aberration 
is Hubner, but owing to want of knowledge of what were and 
what were not species his nomenclature is extremely mixed. 
In ‘Tort.’ he figures it (fig. 91),. but calls it literana; then, 
subsequently, in ‘ Verz.,’ p. 386, No. 3750, he writes—‘‘ figs. 92, 
91 aerugana’”’; but fig. 92 represents a form quite different from 
91. As he, however, in giving the name aerugana places 92 
before 91, it is obvious that in priority the former must take the 
name aerugana. and that the latter is at present without a name, 
and therefore I have given it the above, and describe it as 
follows : 
As literana, L., but with a fulvous longitudinal band on the 
superiors commencing in the centre of the base and forking 
immediately after leaving it; one branch dies out on the costal 
margin about two-thirds of its length from the base, the other 
branch being carried down the centre of the wing until it almost 
reaches the hind margin, where it terminates. 
This extremely handsome form comes nearest to ab. tricolo- 
rana, Haw., but is distinguishable at once from it by the clear 
sreen ground-colour and the absence of black dots, which are 
found in that aberration. Hubner’s figure admirably portrays it. 
It is not very rare in the New Forest, from whence I have a 
beautiful series of twelve examples.
