whitish striga; the principal veins are whitish, which is the case with all of them towards the tip of the wing 
where they intersect a rich, broad, rosy bar, preceding the subapical striga, which is almost obsolete. The hind 
wings are brown ; the thorax rosy, with white markings. The caterpillar is green, with three slender, white, 
dorsal, longitudinal stripes, and a fulvous lateral one. The moth was first taken by Mr. Stephens in 1810, near 
Hertford. It has since been found in Surrey, Kent, Norfolk, Yorkshire, &c.; Chatmoss, Mr. Edleston. 

TRACHEA. Ocu., (wec. Borspuvar, HADENA, p. Gutn, Borsp.) 
The only species in this genus, as restricted by Mr. Stephens, has the head densely squamose, the thorax 
quadrate with a bifid crest in the middle, the segments of the abdomen tufted above, the fore wings elongate- 
triangular ; the antenne slender in both sexes; the palpi densely squamose; the terminal joint distinct, and 
knob-like. ‘The caterpillar is smooth, naked and coloured, with the penultimate segment angulated above as in 
the Mamestree. 
SPECIES 1—TRACHEA ATRIPLICIS. Pratze XXXIX., Fic. 6, 7. 
Synonymes.—Phal. Noct. atriplicis, Linneus ; Wilkes 3, pl. 2; Donovan, vol. 8, pl. 262, fig. 1; Haworth; Stephens; Curtis,

This very beautiful insect measures about 13 inch in the expanse of the fore wings, which are of a somewhat 
ashy tint, clouded with darker brown shades, and varied with yellow or greenish markings. Near the base of 
the wing is the first pale striga, edged with black and crenated ; beyond which towards the hind margin is a large 
pale patch with a dusky centre; the second striga is transverse and very undulated, succeeded by the 
characteristic portion of the wing, the ground of which is rich dark brown; the anterior stigma is small and 
annular, immediately behind which is a small supplemental stigma, margined with black, on which, and the 
preceding, rests a very distinct whitish oblique central patch ; the outer stigma is very large and luteous or 
greenish, with the centre varied with dusky ; the third striga is very much curved and denticulated, slender and 
pale, followed by a various coloured space, which is pale-green or luteous towards the anal angle; the subapical 
striga is slender, pale, and much waved, followed by a darker stripe, the apex marked with a double row of small 
black marks. The hind wings brown, with the margins darker coloured. 
The caterpillar is dark green, with a dorsal and lateral stripe of black, which is also the colour of the incisions 
of the body, a bright fulvous stripe running along the spiracles. One figured by Rdsel, is, however, of a flesh 
colour; it feeds on Atriplex hortensis, Rumex acetosa, &c. The perfect insect is rare, but has occurred in 
distant parts of the country, near London, Wisbeach, Cheltenham, in June and September. 


VALERIA, Geraar, Sreen., Guén. METELLA pars, Botspuvat, 
The typical and only British species of this genus, is at once distinguished from all the other Noctuide by 
having the antennz in both sexes bipectinated, (more strongly in the males); the tips of the pectinations 
thickened ; the palpi have the terminal joint exposed and elongate ; the thorax is robust and slightly crested ; the 
abdomen thick, and the fore wings notched along the apical margin. The caterpillar is naked, having only a few 
scattered hairs ; it feeds on trees.
