OF THE MALTESE ISLANDS. 73 
segments each provided with a pair of very large tubercles (Pl. II, fig. 5), the 
tips of which are furnished with a pair of broad flat appendages ; integument 
thickly covered with squamose spines (PI. IT, fig. 4). 
The larval skin attached to the pupa does not present any morphological 
differences from that of P. papatasti, as far as one can gather from its shrivelled 
condition. It possesses the same kind of caudal bristles and hairy body-spines.

This insect has been described so frequently that it seems unnecessary here to 
do more than add such particulars as have hitherto been overlooked, or 
imperfectly dealt with. In the first place it may be noteworthy to state that 
there are two distinct colour varieties of this common and widely distributed 
species :— 
(1.) A uniformly pale form, which may be considered typical ; 
(2.) A form which differs from the foregoing in having a dark coloured 
fringe to the costa and hind margin of the wing ; herein described as 
the dark form. 
FEMALE.— Typical pale form (immediately after death)—Almost uniformly 
pale translucent ochreous, thorax with a long dull red-brown median stripe, and a 
single spot of the same colour on either side, near the front margin of the thorax. 
Hairs on all parts of the body greyish, their arrangement similar to that of the 
male. Wing relatively broad (fig. 4, p. 62). Wing-fringe not markedly darker 
than the hairs on the dise of the wing. 
MALE.— Typical pale form (immediately after death).—Colour similar to that 
of the female. Clypeus with a tuft of 8-10 hairs ; head with a loose tuft, some 
of the hairs curving forwards, others backwards ; tuft on nape of slightly longer 
ones, chiefly curved forwards. Thorax densely clothed; the hairs arranged in 
loose tufts. Wing much narrower than in the female (fig. 4, p. 62). Abdomen 
uniformly hairy, with small tufts on the dorsum arising from the apical margin of 
each segment ; superior claspers densely hairy, with a few black hairs intermixed 
with the pale ones; these hairs are easily deciduous, with the exception of a 
large tuft which is more or less permanent in examples mounted in Canada 
balsam. 
FEMALE.—Dark form. General colour similar to that of the pale form. 
Wing fringes distinctly smoky grey ; some of the hairs on the veins are also 
dark grey or smoky grey.
