AND THEIR TRANSFORMATIONS. 247 
PHYTOMETRA CRassIuscuLA, Haworth; Stephens (Ophiusa cr.) ; Wood, Ind. Ent. pl. 17, fig. 436. 
Expansion of fore wings 13 inch ; gray-brown, with two darker, broad, nearly straight fascize across the fore 
wings, with a small central dark dot, and a short black streak near the tip of the costa, formed of triangular dots. 
: 
This is common in North America, whence I have received several specimens. Mr. Stephens’ specimen, stated 
by him to have been captured in the north of England, was, I am informed by Mr. H. Doubleday, obtained 
from Mr, Weaver, who had it from some dealer in the north. 
PHYTOMETRA GRANDIRENA, Haworth ; Stephens (Ophiusa gr.) ; has the fore wings blackish-gray, with two 
oblique divaricating pale fascia, between which is a large black kidney-shaped spot ; hind wings pitchy brown, 
with a pale line at the base and apex, and a large central spot. Described by Mr. Haworth from a specimen in 
Dr. Leach’s collection, stated to have been caught at Bristol, and two others from Georgia in North America ; 
whence the indigenousness of the former individual is very questionable. 
Puatmna Noctua LEvcomELas, Haworth; Stephens (Catephia 1.); Wood, Ind. Ent. pl. 54, fig. 54; 
N. alchymista, Hb.; N. convergens, Fab. ; Anophia leucomelas, Guénée. Fore wings blackish-brown, with 
black waves, and a large white spot ; hind wings white at the base, with a broad black border. One or two 
specimens in the old collections were thus named; but one of these now in Mr. Bentley’s collection, is, as 
Mr, H. Doubleday informs us, quite distinct from the Linnean leucomelas, and in fact belongs to a group which 
is purely American in its geographical range. 
CATEPHIA TRIFASCIATA, Stephens ; Wood, Ind. Ent., pl. 17, fig. 437 ; expands 14 inch in the fore wings, 
which are glaucous ashy, with three brownish fasciz ; the hind wings brown, with the margin darker, and two 
pale strigew. This is also, most probably, a North American species. Mr. Stephens received his specimen from 
Mr. Kirby, who is said to have taken it at Barham, in Suffolk. 
DESCRIPTION OF PLATE LV. 
Insects.—Fig. 1. Mormo Maura (the old lady, or great brown bar). 2. The Caterpillar. 
=" Fig. 3. Catocala Fraxini (the Clifden nonpareil). 4. The Caterpillar, 
of Fig. 5, Catocala Nupta (the red underwing). 
“ Fig. 6. 
Catocala Elocata. 
Prant.—Fig. 7. Alnus glutinosa (the common alder). 
©. Fraxini is from the beautiful specimen, recently captured by Mr. 8. Stevens; the others are from the cabinet of Mr. Bentley, with the 
exception of Elocata, from a foreign specimen in the British Museum, there being no well-authenticated British specimen. The Caterpillar of 
Maura is from Hiibner, that of Fraxini from the beautiful figure of Sepp. H. N. H. 
MORMO, Ocusenuemer. MANIA, pe. Trerrscuxe. 
I have already alluded to the relation which exists between Noctua maura L., the type of the present group, 
and N. typica; and, now that figures of the larve of both species are before the student, it will be at once 
perceived that the distinction between the former and the Catocale is much greater than that between the two 
first-mentioned insects. M. maura differs also entirely in its habits from the Catocale, entering houses, and 
flying by night, whilst the Catocale are day-fliers. Mormo has the palpi elevated, with the terminal joint 
distinct and ovate conic. The thorax and abdomen crested, the extremity of the latter not conical ; the wings 
deflexed when at rest, forming a triangle, with the margins crenated ; the fore wings short, broad, and stigma- 
tiferous; whilst the larva is naked and cylindrical, and marked with dark oblique stripes, and with sixteen feet.
