216 BRITISH MOTHS 
of littoralis, pudorina, and phragmatidis, from the cabinet of Mr. I. F, Stephens, comma from Mr. H. Doubleday, and obsoleta from the 
British Museum. In some varieties I have thought it unnecessary to figure such as arcuata, a variety of impura, ochracea, another variety 
of pallens, and fulva, another variety of pygmina. Unipuncta, some time since considered British, is proved to be a North American species, 
having accidentally obtained a place in some old cabinets. The caterpillars are from Hiibner and Freyer; that of impura accords with some 
specimens obtained in the Hammersmith marshes by Mr. 8, Stevens. H.N, H. 
LEUCANIA, Ocusennemer. LEUCANIA and NONAGRIA, pars. GuENEE. 
This genus is closely allied to Nonagria, in which group, indeed, the French Lepidopterists introduce some of 
the following species. The typical Leucaniz are, however, distinguished by their small size, the antennz nearly 
alike in both sexes ; scaly above, and thickly ciliated beneath ; the thorax is not crested, the abdomen long and 
slender in the males, the fore wings narrow and acute at the tip. The caterpillars are described by Stephens as 
not being internal feeders, slightly pilose, and feeding on leaves, and the pupa is inclosed in a web, according to 
Ochsenheimer. How far the latter characters will apply to all the following species is doubtful, since our 
figures, 4, 12 and 14, evidently represent two different types of larvee. 
SPECIES 1—LEUCANIA STRAMINEA, Prare XLVII., Fie. 1. 
Synonyme.—Leucania Straminea, Treitschke ; Boisduval ; Nonagria Vectis, Curtis, Brit. Ent. pl. 459; Stephens; Wood, 
Freyer. Ind. Ent. pl. 52, fig. 1669. 
This species measures 11 inch in the expanse of the fore wings, which are alternately marked with numerous 
longitudinal ochreous and cream-coloured lines, the nervures being pale ; the central nervure suffused with reddish 
ochre, as well as the one next the interior margin, which is slightly freckled with black: at the disc is a fuscous 
dot, and an imperfect curved line of similar dots, between it and the posterior margin, which bears seven black 
dots, the posterior angle emarginate ; hind wings white, lightly tinted with ochre, and freckled with brown below 
the centre, where there is a pale spot shining through from beneath, The obscure line of fuscous dots is continued 
across their wings ; they are somewhat oval, and there are a few dark dots on the margin, Curtis, Brit. Ent. 459. 

Taken in the Isle of Wight and at Whittlesea Mere in July, also in the Hammersmith marshes in June, by Mr. 
S. Stevens—in company with Leucania obsoleta. } 
SPECIES 2.—LEUCANIA COMMA. Puarte XLVIL., Fie. 2. 
Synonymes.—Phalena Noctua comma, Linneus; Treitschke ; Noctua turbida, Hiibner (teste Stephens). 
Haworth; Stephens; Wood, Ind. Ent., pl. 15, fig. 359. Noctua congrua Hiibner ? 
Noctua pallens, Esper. Noctua impura, Hunber (teste Boisduval), 
This species measures nearly 14 inch in the expanse of the fore wings, which are of a pale ashy brown, with 
a black central line at the base, extending behind the median vein, as far as its first branch; a similar but shorter 
and slenderer line extends behind each of the longitudinal branches, beyond the middle of the wing ; the costa is 
paler luteous brown ; the disk darker brown; the veins whitish, with a slender margin of pale brown on each 
side. At the extremity of the discoidal cell is a black dot; the apical margin of the wing has a row of minute 
black dots, between which extend the white veins into the ciliw; the hind wings are of a shining 
gray brown, 
with pale ciliz ; the thorax has a slender dark arch in front. 
The caterpillar is naked, reddish brown, dotted and striped with black on the back; the first seoment 
scutellated with black, with three white lines; it feeds on the common sorrel]. The moth is rather abundant, 
and appears in June and July.
