AND THEIR TRANSFORMATIONS. 133 
The only specimen of this insect yet indicated as British is one placed by Dr. Leach in the British Museum 
collection, the figure of which, given by Mr. Wood, exhibits a strong variety, if, indeed, it be specifically 
identical with the true Musiva. In this the anterior stigma is distinct, and preceded by a triangular black 
patch, and followed by a transverse patch of the same colour, by which it is separated from the second stigma ; 
there is also a black V-like mark behind the anterior stigma, and several short black spots towards the apical 
margin of the fore wings. The species occurs on the Continent in August. The caterpillar is figured by 
Hiibner of a yellowish green colour, with two longitudinal white streaks and a brown head.

This very distinct species measures 1} inch in the expansion of the fore wings, which are of a brownish 
purple colour, the costa, from the base to beyond the middle and the stigmata, being of a whitish buff tinged with 
reddish ; a black striga runs from the base along the middle of the Wing, cut in two near the base by the great 
median vein, and subsequently interrupted by the stigmata: near the apical margin is an ill-defined pale streak, 
and the apical margin has a row of black dots. The hind wings are almost white, with luteous ciliz. 
The caterpillar is dark green, speckled with white and black dots, a brownish dorsal line and pale yellowish 
lateral ones above the feet. The head brown. It feeds on celery, beet-root, endive, and other herbs, in May 
and August ; the insect appearing to be double-brooded, and flying at the end of June and beginning of 
September. It is a rather common species.

Orthosia gracilis, O. upsilon, O. lunosa and var., and O. pusilla, are from specimens in the cabinet of Mr. Bentley. The rest are from 
specimens, for which I am indebted to Mr, H. Doubleday, who has also procured for me the larva of S. gothica, which is figured in plate 29, as 
is also that of O. cruda (ambigua Hubn.). The larva of O. Upsilon is from Hiibner.—H. N. H.

The typical, and indeed only species, upon which the present group has been proposed by Mr. Stephens, has 
the fore wings more elongated and less truncate at the tip than in the Graphiphore, whilst its strong markings 
separates it from the Orthosiz, with which it is united by Boisduval. It is from this latter character that the

the males are strongly bipectinated, on which account it has been united wlth Episema; the thorax is very 
thickly clothed with woolly hairs, the hind wings are rather small, and the body rather short ; the palpi have 
the apical joint exposed, and slightly porrected in front of the eyes. The caterpillar is naked, and has the
