AND THEIR TRANSFORMATIONS. 155 
more or less varied with a buff edging, which is united to an interrupted oblique striga, reaching nearly to 
the apex of the costa. Between the outer stigma and the margin of the wing are several black dashes, 
above which, in some specimens, is an oblong patch of buff, as in our figure. The hind wings are 
snow-white, with the veins and slender hind margin blackish; the cilia White. Varieties occur, in which 
the wings are much more saturated in their colouring. Of these, the individual figured by Mr. Wood 
differs materially from our figure. Mr. Stephens, in his Catalogue, gave one of these varieties as the 
Ph. N. perspicillaris of Linnzus ; he, however, referred :t, in his Illustrations (under No. 6183 instead of 6182), 
to a variety of this species, remarking also in the latter work (vol. iii., p. 94), that the Linnzan species was 
probably a species of Calophasia, and that he believed it was contained in Mr. Swainson’s cabinet*. The eyes 
in this species are pubescent, and the male antennz subserrated. The species thus forms a distinct section, and 
indeed, as above mentioned, it forms a distinct section in the genus Luperina of Boisduval +, who gives April as 
‘the time of its appearance in the perfect state ; whilst our English authors mention the end of May. It isa 
very rare species, but has occurred in Bulstrode Park, and near Birch Wood in Kent. The caterpillar is dirty 
green, with a pale lateral line edged with brown. It feeds on Astragalus, Onobrychis, &c.

Synonymes.— WVoctua semibrunnea, Haworth; Stephens, Ill. H. 2, pl. 21, fig. 3; Wood, Ind. Ent. pl. 11, fig. 221. 
This species measures 1.7. inch in the expanse of the fore wings, which are remarkably long and narrow, 
the anterior or costal division being of an ashy brown colour, and the hinder division dark brunneous ; they are 
slightly clouded with darker tints, especially in the region of the stigmata, all three of which are present but 
very indistinct; the veins are dotted with black, and near the apex of the wing they are striped with thin black 
lines ; towards the inner margin, however, these stripes become much broader, and are interrupted towards the 
anal angle ; the apical margin is marked by a row of deeply-angulated dark spots; the hind wings are paler 
and shiny, with the base and cilia pale, and with a dusky central lunule ; the abdomen has a row of blackish 
tufts down the middle ; the wings beneath are paler, with a dark spot on the middle of each. This is a rare 
species, but has been taken at Coombe Wood, and also at Mickleham, in October, by Mr. Douglas, from the 
flowers of the ivy. 

SPECIES 6.—XYLINA PETRIFICATA. Purate XXXI., Fie. 4. 
Synonymes.—WVoctua petrificata, Wien. Verz.; Fabr.; Ochs.; | Noctua petrificosa. Hubner.

fig. 222. Noctua socia, Hufnagle. 
This species, which has been confused with the preceding, measures 12 inch in the expanse of the fore wings, 
which are of a greyish ochre colour, with darker clouds, with a dark longitudinal stripe towards the base, and 
another behind the stigmata, which are pale ochre-coloured, the space between them being dark ; the costa is 
marked with several blackish dots ; beyond the stigmata is a double curved row of dots, and beyond these a series 
of dark cuneated marks, forming an angulated striga, emitting several paler streaks; the margin itself is dotted 
with brown ; the hind wings are brown, with the base paler, and a subcentral row of obscure dots on the veins ; 
the abdomen is ochre-coloured, without the dark tufts. Very rare, but taken in Devonshire by Captain Blomer 
and Mr. Marshall, as also in Norbury Park by Mr. Walton, in September. 

* Boisduval gives N. perspicillaris as one of the three species of his genus Cloantha. Mr. Paget has taken it at Yarmouth. 
+ Guénée unites it, with Pinastri, into a section of his extended genus Cloantha.
