OXIGRAPHA LITERANA, L. 
buff ground-colour of the superiors, it resembles in all respects 
ab, squamana, Fab. ~ 
The only specimen I have seen of this aberration is one which 
~ came from the New Forest during September, 1919, but Kennel, 
‘Pal. Tort.,’ taf. v, fig. 4, figures a very similar but slightly 
browner form, which he incorrectly terms irrorana, Hub., from 
‘* Schilka, Collection Grand Duke Nikolai Mikhailovitch.”’ 
Ab. irrorana, Hub. (Plate I, fig. 8.) 
Synonymy.—Irrorana, Hubn., Tort., fig. 96 (1797); Hibn., 
Verz., p. 886, No. 3751 (1826) ; Curtis, Guide, p. 173 (1829) ; 
Stephens, Cat., p. 188, No. 7097 (1829) ; Rennie, Conspect., 
p. 180 (1832); Curtis, Brit. Ent., pl. 440, and No. 4 (18383) ; 
Stephens, Haust., iv, p. 165 (1834); Wood, Ind. Ent., fig. 1100 
(1839) ; Westwood, Brit. Moths, pl. 96, fig. 12, and p. 164 (1845) ; 
Staudinger, Cat. Lep. Hur., p. 94 (1861), and p. 284 (1871) ; 
Frey, Lep. Schweiz., p. 284 (1880); Snellen, Vlinders, p. 176 
(1882) ; Spuler, Schmett. HKur., p. 242 (1908) ; Wagner, Lep. Cat., 
par. x, p. 69 (1912). 
Hiibner’s fig. 96 is unmistakable, but there is no description. 
The figure shows the superiors with greyish-green ground- 
colour thickly sprinkled with intensely black dots. It has the 
usual transverse lines, which are generally not apparent in 
British examples, or that are only faintly indicated in a few 
instances. Ab. irrorana is perhaps the most beautiful of all the 
literana forms, the black dots on the light green ground showing 
up very prominently, and contrasting exquisitely with them. 
It is well figured also by Curtis and Wood. The former’s figure, 
which is slightly enlarged, is the best of all. Both these authors, 
of course, depict the English form. 
Trrorana is not by any means an abundant form; it occurs in 
most of the localities in which the species is found. I have eight 
examples from the New Forest.

Ab. squamulana, Hub. (Plate I, fig. 9.) 
Synonymy.—Squamulana, Hubn., Vogel, fig. 14 (1793); Hiibn., 
Tort., fig. 95 (1796) ; Hubn., Verz., p. 886, No. 8749 (1826) ; 
Frey, Lep. pee p. 284 (1880) ; : Snellen, Vlinders, p. 176, 
No. 11 (1882) ; Wagner, Lep. Cat., par. x, p. 69 (1912). 
Hubner, of course, does not describe this aberration; his 
figs. 14, ‘Vogel,’ and 95,‘ Tort.,’ are identical, except that in the 
former the dise of the superiors is greyish, whilst in ‘ Tort.’ it is 
dark sage-green. In ‘ Tort.’ he names figs. 92, 98, 94 and 95 
as squamulana, but only the last figure agrees with his figure in 
‘Vogel.’ Fig. 92 is what he subsequently in ‘ Verz.’ ‘named 
aerugana. In this work he retains the name squamulana for the 
other three figures. These three figures represent forms about
