var. latefasciata, Stgr., and var. brunneata, Pack , = suspnctata, Moschl., 
Stgr., I refer provisionally to citrata. Hampson (lml. Moths, iii., 
p. 878), who does not discriminate between truncata and citrata, cites 
subapicaria , Moore, calamistrata, Moore, cinereata, Moore, and albi- 
angulata, Warr., as vars. of truncata. I incline to call subapicaria an 
ample-winged var. of citrata, or a valid species, some details, perhaps, 
suggesting the latter ; it has the central area normally black, the pale 
spot behind it, on costa, sharply expressed, and sometimes broadened, 
often also, a clear pale apical mark just above the black one; the hind- 
wings are darkened, sometimes much darkened ; the angle in the line 
on their underside is only moderate. Cinereata, I suggest, is most 
probably “ bon. sp.,” though perhaps it is not absolutely impossible it 
might prove to be a var. of truncata. It is a very pretty characteristic 
form which the British Museum possesses, labelled “Bengal,” 
“Darjiling,” and “ Moupin,”* mainly whitish, faintly powdered, the 
basal and apical areas coloured in blackish and sienna, the outer sienna 
band reduced to two distinct blotches (costal and inner-marginal). 
According to Warren, it has also an aberration with median area dull 
yellowish (ab. fiavifusa, Warr., Nov. Zool., iii., p. 887); a strange- 
looking “ sport ” from Dharmsala, in the British Museum collection, 
may be a phase of this; it has no markings, except a dark basal, and 
an extended dark apical patch, a ferruginous mark on inner margin 
near tornus (characteristic of cinereata), two very obscure, pale ferru¬ 
ginous lines at inner margin, representing the termination of the usual 
double elbowed line, and a tawny suffusion over the greater part of the 
broad white area. Calamistrata might possibly be a darker form of 
cinereata, like which it has the dark inner marginal blotch representing 
the end of the outer sienna band; it is a clearly marked form—in this 
resembling citrata —the central part white, the sienna fairly bright, yet 
the shape of the markings is more suggestive of truncata. Warren 
(Nov. Zool., iii., p. 887) has erected a P. calamistrata ab. albimedia, 
with “ the median fascia broken up by white scaling,”! and “ the hind- 
wings pure white, whereas in calamistrata they are always more or 
less tinged with grey.” Hampson makes this calamistrata “ the 
nearest to the typical European form,” from which he merely cites 
its white abdomen and hindwings as differential. Albiangulata I 
only know from a solitary specimen at the British Museum from 
Yatung, Tibet; Warren, in erecting it, hesitated whether to make it 
a species, but Elwes, its captor, added a note in the affirmative, and 
I am inclined to agree, the shape of the markings being so distinct. 
Cidaria citrata—immanata is given by Staudinger as inhabiting 
central and northern Europe (except Hungary and south-west Russia), 
Iceland, Kamtchatka, Behring Island, Japan ?, Amdo, and central and 
western China, those from the last-named localities being “ var ? an 
* Some Dharmsala specimens that are added, are different, probably a form 
of citrata. The Moupin example was referred by Leech to his non-cutereata form, 
but his two forms seem to me not very distinct. 
f This is a curious differentiation, as Moore’s type specimen has nearly three- 
fourths of the median fascia white, being only fuscous in the outer half from costa 
to vein two. Also its hindwings are white, except at outer margin, so I suspect 
Warren must have been taking some aberrational form as typical, and has virtually 
redescribed the type.
