the head and thorax very pale ochreous or whitish, the ground colour 
of fore-wings whitish tinged with grey or ochreous, and a fascia rising 
on the inner margin of fore- wings a little before the middle, and crossing 
the wing nearly parallel with the hind margin. Briefly I would de- 
scribe them as follows : — 
Suhroseana, Haw. Fore-wings broad, costa and hind margin rounded. Ground 
colour whitish-oclireous, tinged with reddish beyond the middle, and with the 
entire apical portion reddish-brown. Fascia broad, reddish-brown, not very 
oblique, and barely touching the costa. Apical fringes dull ochreous spotted 
with reddish-brown. Hind-wings dark grey. 
Heydeniana, H-S. Fore-wings broad, costa and hind margin rounded, whitish, 
deHcately reticulated with grey, and with a faint rosy or pinkish suffusion, 
especially towards the apex. Fascia greyish-brown, slender, slightly inter- 
rupted and bent back near the costa. Apical fringes very slioH, ochreous 
dotted with grey, and with a distinct dark line along their base. Hind-wings 
pale grey. 
In this species I cannot entirely confirm Mr, McLachlan's descrip- 
tion. The rosy suffusion is very distinct in my specimens, but totally 
different from the rich orange-red or reddish-brown of the apical portion 
of the wings of suhroseana. 
Ciliella, Hiib. Fore-wings long and narrow, and much pointed at the apex. Costa 
and hind margin nearly straight. Whitish-ochreous, fascia very oblique, 
parallel indeed with the hind margin, and barely reaching the costa j yellowish- 
brown or reddish, varying greatly in colour and distinctness. Beyond it, on 
the inner margin, and before the anal angle, is a triangular spot, and along 
the hind margin an indistinct band, both of the same colour as the fascia. 
Apical fringes very long, dull yellow. Hind-wings pale grey. 
Degreyana, McL. Fore-wings long and narrow, margins nearly straight. Greyish- 
white with a pink tinge, which becomes very decided towards the apex. 
Fascia reddish-brown, t^ery slender, indistinct beyond the middle of the wing, and 
becoming obsolete before the costa. Apical fringes bright ochreous. Hind- 
wings dark grey. 
Thus suhroseana and Heydeniana have broad wings and rounded 
margins, the former having an orange-red apex and spotted fringes, 
and the latter very short fringes with a dark line at their base. 
Degreyana and ciliellahaye long narrow wings with straight margins, 
the former a slender abbreviated fascia and pink apex, and the latter a 
broad entire fascia and marginal band, both parallel with hind margin. 
Finding last spring that the supposed suhroseana which I have 
been in the habit of occasionally taking was likely to prove a novelty 
(Heydeniana), I resolved to work carefully for it, and, if possible, take 
a lot for my friends, this being apparently practicable, since it appears
