PTOCHOPHYLE. By L. B. Prout. 
155 
A. Section. Antenna of $ not pectinate. 
Pt. marginata Warr. (16 g). Hindwing almost regularly rounded. Very distinct in the unusual shape marginala. 
of the grey distal border of the forewing. Only known from the Khasis. 
Pt. pulverulenta Warr. (16 h). A very obscure and little-known species, founded on a $ from Perak, pulverulenla. 
to which has been added a closely similar one in better condition (here figured) from Kuching. Sarawak. Not 
quite so small as inornata, the costa of the forewing relatively somewhat more elongate; perhaps merely a race 
thereof. Colour and (so far as discernible) the markings similar. Underside unmarked. 
Pt. inornata Warr. (16 h) has much of the aspect of a rather round-winged Sterrha, but the marginal inornata. 
dots (which are moderately large) are placed on the wings, not on the fringes, and are interneural, while very 
minute dots are also discernible on the vein-ends, pointing to the Anisodes relationship. Underside paler, with 
the slightly elongate cell-marks reproduced and with the broad, pale subterminal accompanied proximally by 
an ill-defined, twice outbent darkish shade. Founded on 3 <$<$ from the Tenimber Islands, which are a little 
darker and more uniform-looking than the other forms, unless perhaps the sole specimen known from the Kei 
Islands. - sordida Warr., from the Louisiades (type from Rossel), is perhaps synonymous, but looks a little sordida. 
lighter and more ochreous-tinged, the postmedian dots a little more connected by a line and separated from 
the median shade by an appreciably lighter band. Here, too, may belong a $ from Ron 1. and a A from Rook I. 
Unfortunately I have not seen any quite fresh example. stolida {Warr., MS.) Prout (16 h) is closely like stolida. 
sordida. perhaps not separable, but has the characteristic pattern of the underside more sharply expressed on 
the forewing, the hinclwing beneath rather white, the subterminal here, and sometimes on the forewing beneath, 
inclined to extend to the termen. Bougainville (type series) and Guadalcanar, presumably also on some of the 
intermediate islands. 
Pt. exitela Prout (16 h). Distinguished by the broad pale wings, the cell-dot- of the forewing rather exitela. 
large, black, that of the hindwing white, slightly elongate; hindwing with termen subcrenulate; underside with 
the subterminal enclosed between flesh-pinkisli shades, the proximal one interrupted or macular. Celebes: 
Dongala, S. of Palos Bay. 
Pt. prouti B.-Bak. (16 h). Smaller, yellower, the distal margin of the forewing somewhat more gibbous, prouti. 
Variable in the amount of purple grey clouding; in the more typical forms this is only conspicuous in the vicinity 
of the anal angle of the hindwing. — In ab. griseofusa nov. the clouding covers almost the entire surface of both griseofusa. 
wings as far as the subterminal and, by way of compensation, the terminal area remains almost as clean yellow 
as the subterminal, prouti is known from British New Guinea (the type from Dinawa) and Mt. Goliath. 
Pt. albidisca Warr. (16 h). Rather larger than exitela, forewing longer costally, hindwing somewhat albidisca. 
more crenulate. Much more clouded with greyish fawn, sometimes with some blackish maculation towards 
the tornus of each wing; a pale (buff or yellowish) band between the median and postmedian of fore wing; cell- 
spot of forewing large, greyish, indefinite, that of hindwing white. British New Guinea (the type from Biagi) 
and the Snow Mountains. 
Pt. strigata Warr. (16 h). More ochreous than exitela , the diffuse greyish markings much stronger, strigata. 
particularly in the type, which is unfortunately the only $ yet known. The £<$■> of which we figure one from 
Kulambangra. vary very little. The underside is considerably more strongly marked than that of exitela-, the 
shade or band which accompanies the subterminal proximally is uninterrupted, the terminal shade slightly 
interrupted. Solomons, distributed, the type from Guadalcanar. 
Pt. tristicula Swinh. (16 h). A small and inconspicuous species. The almost straight median shade, tristicula. 
particularly on the hindwing, where it touches the white cell-dot, is distinctive, as also, in strongly marked 
specimens, the character of the grey clouding of the tornal region, that of the fore wing enclosing a pale spot 
in the submedian area; this is present also in weakly marked specimens, though less conspicuous. Hindwing 
not angled at 3rd radial. Described from Bombay; distributed in Ceylon, India, Burma, Luzon, Sambawa, to 
which range additions will certainly be made. 
Pt. volutaria Swinh. (16 h). Very similar to tristicula except in shape; forewing with termen sinuous, volutaria. 
the apex acute, the midtermen gibbous; hindwing angled at 3rd radial. Also described from Bombay and known 
from Ceylon and several stations in India, besides the Malay Peninsula. 
Pt. virgata West (16 i). Hindwing angled about as in volutaria, or rather — on account of a faint con- virgata. 
cavity in the termen between the 2nd subcostal and the angle — appearing a little more irregular. Wings more 
regularly reticulated, postmedian of forewing distinct, with yellow maculation proximally, hindwing also -with 
a conspicuous yellow spot just outside the cell. Benguet, Luzon, 1 Probably quite near the following.
