Moths in the Joicey Collection. 291 
forming bright but slightly interrupted bands posteriorly on 
the segments; crests light greyish ochreous ; sides of base 
blackish ; underside white. Fore and middle legs largely 
blackened, the femur and part of tibia remaining white on 
outer sides; hind leg whiter, but irrorated or clouded with 
grey, 
Fore wing broad; SC? wanting (sport?) ; white, irrorated 
with olive-grey and very sparsely with black, the proximal 
and distal areas also with bright ochreous, the veins in these 
areas broadly, in the median area very slenderly, bright 
ochreous; an ill-defined blackish band or shade close to base, 
not reaching costa; antemedian line thick, black, at little 
beyond one-fourth, very gently curved, at M and SM? very 
slightly dentate inwards; median area more olivaceous 
costally and with long, not very strong, olive-grey cell-mark ; 
postmedian line black, from beyond two-thirds costa to about 
three-fitths hind margin, strongly dentate outwards on most 
of the veins, feebly so on SM?, nearest the termen at R® and 
the medians, retracted behind M?; subterminal white line 
distinct between M? and hind margin, running obliquely 
towards tornus, very. faint in the rest of its course; some 
ill-defined whitish dots to termen. 
Hind wing with subbasal shade slight, antemedian line 
wanting, no ochreous proximal area ; hairs of median area 
_ bright ochreous; postmedian line finer than on fore wing, 
otherwise similar ; distal area nearly as on fore wing. 
Underside dirty white, with rather broad black borders 
containing large white terminal spots, so that the black only 
runs to the termen between the radials, around M? (in both 
these places more narrowly on hind wing), and at tornus ; 
base, especially at costa, bright yellow; fore wing with a 
vather large dark discal mark. 
A’koon, Gold Coast, 17th Jan., 1919 (C. Harrison). 
The first-known African species of the genus to approach 
in colour P. venusta, Warr. The blackish subbasal markings 
also distinctive.

My type g, described in Wytsman’s ‘ Genera Insectorui,’ 
fase. 129, p. 149 (1912), from asingle somewhat damaged ¢ 
in the British Museum, has hitherto remained unique. A 9? 
from T'ananarive, recently acquired by Mr. Joicey, is some- 
what larger (33 mm,), rather broader-winged, the termen 
slightly more waved, that of the fore wing a little more con- 
vex (compare the sexual difference in G. spumata, Warr., and
