164 BRITISH MOTHS 
SPECIES ? 6.—HADENA OBSCURA. 
Synonyme.—Voctwa obscura, Haworth ; Stephens; Wood, Ind. Ent. pl. 52, fig. 1663. 
The following is Mr. Haworth’s description of this doubtful species: — “Closely allied to H. remissa, 
contigua, &c., and perhaps only a variety of one of them. The fore wings are more obscure or snnOae-ASAY, 
with a large paler patch at the base of the costa, adjoining to which within, are several ae black lines ; Me 
the posterior margin is a nearly obsolete, undulating, slightly-pallid striga; the hind wings ashy-brown.” No 
locality is given to the species by Haworth. 
SPECIES 7.—HADENA GLAUCA. Purarze XXXIII., Fie. 7, 8. 
Synonyme.—WVociua glauca, Hiibner ; Haworth ; Ochsenheimer ; Godart ; Boisduval ; Stephens; Wood, Ind. Ent. pl. 12, f. 239. 
This and several of the succeeding species constitute a small group, first pointed out by Mr. Haworth under 
the name of Noctuze fisso-notata, on account of the fore wings having a small, pale, notched mark in the 
centre ; they constitute Boisduval’s eighth section of Hadena. Their pupz also differ from the rest of the 
genus, having the hinder segments produced into prominent angles, giving them the appearance of being 
dentated. 
The present species measures about 11 inch in the expanse of the fore wings, which are of a glaucous brown 
colour, clouded with lighter shades; the costa marked with several black spots, indicating the origin of the 
ordinary strige, which are not very distinct, but are edged with black on both sides; the anterior stigma is 
rather obscure and edged with black, having a spot of the same colour behind, and adjoining to it, also edged 
with black ; the second stigma is large and pale, with a dusky centre, and edged with black ; beyond it the wing 
is paler, and has a very curved and not very distinct striga ; and towards the hinder margin is a not very distinct 
pale striga, having several black arrow-headed marks towards the anal angle, placed upon the less strongly 
defined W-like mark. The hind wings are brown, with a yellowish tinge. 
The caterpillar is yellowish-red marked with brown, with a paler dorsal line, and a blackish spot on each 
segment ; and on each side of this line is a whitish dot, edged with blackish. It feeds, in July and August, on 
Tussilago farfara and Cypripedium calceolus ; and the perfect insect appears in May and June. It is a rare 
species, but has occurred near London, Cheltenham, and Matlock. 
Note.—Mr. Curtis states that he possesses a fine male specimen of a Hadena taken at Kinnordy, which agrees pretty well with Godart’s 
figure of Hadena Lappo (vol. 7, pl. 116. f. 3), and which he suspects may be the male of H. glauca. 

SPECIES 8.—HADENA PLEBEIA. Puare XXXIII., Fie. 9 
SynonyMes.— Voctua plebeia, Linn. 3 Haworth; Stephens ; Curtis; Noctua nana, Esper (variety). 
Wood, Ind. Ent. pl. 12, fig. 240. 
Noctua dentina, Fabr. ; Hiibner ; Haworth (variety).

Noctua leucostigma, Haworth ; Stephens (variety). 
This species also measures about 1+ inch in the expanse of the fore wings, which are much more variegated 
than in the last species; the costa pale, with about eight black spots, the two basal ones succeeded by a waved 
striga edged with dark colour, which does not extend to the inner margin of the wing, but is inflexed towards 
the base, and succeeded on the disc of the wing by a pale patch with two black dashes ; beyond which is the 
second striga edged with dark colour, and nearly straight ; then follow the two stigmata, the basal one with 
a dark patch adjoining to it on either side ; the stigmata are pale; the outer one, however, brownish in the 
inside, the space before and beyond the basal one, dark brown, as also beyond the second one, which is divided 
by pale longitudinal stripes. The supplemental stigma is dark coloured and rather small, resting upon a blackish
