of taeniata Steph. (Vol. 4, pi. 8 e); their life-history is still unknown, but it may be conjectured that it will prove 
to be similar to that of taeniata and will possibly constitute it a separate genus, interrupta is considerably larger 
than fasciata, the markings more blurred, the pale band outside the postmedian broad (in fasciata narrow), the 
outer white spot reaching the 2nd median, the hindwing slightly darker, at least at the margin, the underside 
of the forewing slightly better marked than in fasciata. 
P. mediangularis Prout (Vol..4, pi. 12 c, as mediangularia). Probably near interrupta, but almost as 
strongly glossy as variabilis, than which it is larger, somewhat more tinged with red-brown and with scattered 
bluish scales; subterminal line bluish white, somewhat punctiform, but with a V-shaped mark pointing inwards 
at the 3rd radial. Szechuan, the type from Omei-shan. 
P. variabilis Warr. (27 h). As a good deal of confusion has prevailed regarding this Perizoma, I gave 
a rectification in Suppl.-Vol. 4 (p. 164) and am now providing an authentic figure of one of the originals from 
Tonglo, Sikkim, 10 000 feet. Smaller and perhaps even more glossy than mediangularis; the lustrous blue- 
white or greenish-white scales conspicuous on the forewing, especially between the 2nd submedian and the 
hindmargin, where they commonly coalesce into small spots which define the dark lines; similar dots usually 
present at the termen and always on the subterminal; median area scarcely darkened into a band. Hindwing 
above glossy white. Head not so light as in lucifrons. though the face shows a sprinkling of grey scales, which 
are occasionally somewhat more copious. — ab. (?) albimacula Prout. Central part of the subterminal, which 
in the type-form is somewhat wedge-shaped or may approach that of mediangularis, enlarged into a round 
spot. Tonglo, with the typical form; the original 3 are all 9, but this is probably a mere chance. One of them 
was figured by Warren as “variabilis" , but is really his “third form”, not his type; it is not even certain that 
it is conspecific, since it looks slightly rounder-winged. — condignata Prout (= seriatavar., Butl., nec Moore) 
(Suppl.-Vol. 4, pi. 16 a), from Dharmsala, was at first confused by me with albimacula but is very distinct, not 
unlikely a separate species. Very small (20—22 mm), without lustrous scales, basal and median areas of fore- 
wing darker banded, subterminal dots before and behind the central white spot enlarged, hindwing darker 
than in variabilis, beneath more weakly marked. The originals were collected by “sugaring”; they fed with 
the wings erected, like many Larentiines. I do not think it has been taken since. 
P. antisticta Prout (Suppl.-Vol. 4, pi. 16 a). 23—27 mm. Not quite so glossy as variabilis, anal tuft 
darker. Fore wing with a very conspicuous dark basal or subbasal band; median area generally broader, at 
least, anteriorly, its boundaries defined by dark costal and hindmarginal spots; subterminal slender and much 
interrupted, in the middle crossed by an irregular buff-tinged mark which runs broadly along the 3rd radial 
and throws out a curved projection to the 1st median. Hindwing slightly more grey-tinged than in variabilis, 
cell-dot and nearly always a dark terminal shade present. Punjab: Thundiani (?); also 1 $ from Sultanpur. - 
methemon subsp. (? sp.) nov. (27 li). Slightly broader-winged and less glossy, more variegated; forewdng with 
the pale areas tinged with buff, the greyish median shade not quite reaching the postmedian, which stands 
out with conspicuous dark marks on the veins. Hindwing above with distinct indications of a punctiform post- 
median. Kashmir (T. B. Fletcher): Gulmarg, 23 July, type 9 in my collection; Yusimarg, 6—15 August, 
a similar $ in that of the Agricultural Research Institute, Pusa. 
P. lucifrons Prout (27 h) differs from variabilis in its pale head and in having a conspicuous white spot 
or transverse line at the base of the abdomen above, followed posteriorly by a bright, somewhat tawny trans¬ 
verse line or narrow band. Forewing a little broader, hinclwing scarcely so white, with apex slightly cloudy, 
beneath more powdery. Smaller, less glossy and less brown than mediangularis, band rather broader, etc.; the 
smooth grey-tinged hindwing is similar in the two, but the line of the hindwing in perhaps rather more bent 
beneath and less distinct above. Kachin Hills (loc. typ.) and Sikkim. — lychnobia Prout (Suppl.-Vol. 4, pi. 16 a), 
from Tupako (Mupin), is somewhat darker, at least on the abdomen and hindwing, the characteristic maculation 
of the abdomen weaker; forewing with the relatively large white subterminal dots in cellules 3 to 5 and oblique 
buff spot outside them well developed. 
P. bicolor Warr. (27 i). Distinguishable by its glossy rufous tone, very restricted basal area, slight and 
punctiform subterminal and relatively broad, dentate-edged median band. Sikkim, a single taken at light 
at about 12 000 feet by Elwes. The British Museum has a 9 from Yatong, Tibet. 
P. apicistrigata Warr. (27 i). Very distinct in the form of the strong dark markings, notably those which 
accompany the subterminal; apparently not variable. Sikkim: Nepal frontier, 10 000—13 000 feet 
P. fulvimacula Hmps. (= fulvistriga Warr.) (Vol. 4, pi. 13 m, as affinis). This was erected by Hampson 
in 1896 as nom. nov. for the species which he erroneously described from the N. W. Himalayas in 1895 as affinis 
Moore (see below). The specimens before him in the British Museum came from Dalhousie and Dharmsala and 
as he had indicated no type. Mr. Tams has selected a Dalhousie 9 which best fits his description. Warren's
