SPECIES 1.—DYPTERIGIA PINASTRI. Prater XXX., Fie. 16. 
Synonymes.—Phal. Noctua Pinasiri, Linn.; Hiibner; Haworth ; Stephens ; Wood, Ind. Ent. pl. 11, fig. 217 ; 
Donovan, 10, pl. 347, fig. 2. Noctua Dypterygia, Hufnagle. 
This species measures nearly 14 inch in the expansion of the fore wings, which are black or blackish brown, 
with the three stigmata indicated by darker edges; the costa with darker dots, indicating the place of the strigz, 
and several minute white ones near the tips ; the inner margin of the wing is pale ashy brown, as well as a 
large, irregular, subapical patch, somewhat resembling a bird’s wing expanded, near the angle of the fore wings, 
edged within with black, and with several black subapical dashes ; the hind wings are brown, with the margin 
broad and darker. The caterpillar is dark brown, with blackish dots, with two pale longitudinal lines and several 
oblique lateral ones. It feeds on various species of Rumex, and the moth appears in May. and June. It is rather 
rare, occurring in places where pines abound.

Figures 1, 2 and 4, are from specimens in the British Museum ; the others are all from specimens sent to me by Mr. H. Doubleday. The 
caterpillars arefrom Hiibner.—H. N. H. 
XYLINA, Trerrscuxe. 
This group, as restricted by Mr. Stephens, is distinguished by the quadrate thorax ; the short, nearly horizontal 
palpi, with the terminal joint more or less exposed ; the antenne simple or but very slightly serrated in the males ; 
the eyes naked, except in X. conspicillaris ; the fore wings rather long and narrow, with the tips obsoletely 
dentated ; and the caterpillar naked, or but slightly pilose. The group is, howeyer, by no means so natural as 
could be wished, since Putris and Lambda have respectively a very different habit from the others, Semibrunnea, 
for example ; which last possesses a much stronger resemblance to the Calocampz; in fact, N. putris, Linn., is 
given by Boisduval as an Agrotis, and Conspicillaris as a Luperina; whilst Mr. Curtis, who, in 1829, united the 
Calocampze, Xyline, and Dypterigiz into one group (Brit. Ent. 256), separated a portion under the name of 
Rhizolitha, in 1833 (Ent. Mag. i., 186),

This species measures from 13 to 14 inch in the expanse of the fore wings, which are of a very pale greyish 
white, with numerous small blackish dots on the costa, chiefly placed in pairs; near the base of the wing Is a
