margin blackish. — $ larger (expanse of wings: 26, length of forewings: 14% mm), the wings still lighter, veins 
3 and 4 of the hindwing on a very short footstalk. Formosa, in April, May and November. Types in the 
German Entomolog. Museum at Berlin-Dahlem. 
P. fulvonigra Sioinh. (44 c). E and $ show blackish antennae, the palpi, frons, head, thorax and 
forewing above being ochreous, the hindwing black with a broad ochreous margin. Abdomen black, anal brush 
of the $ yellow. Under surface of body and of the wings, as well as the legs yellow, both wings proximally 
somewhat blackened. — The Erf vary somewhat. Expanse of wings: E 24%, $ 29.4 mm. Guadalcanar-Island 
(Salomons). 
P. pulverea Hmps. (45 b). white, head and thorax somewhat brownish-yellow, antennal pinnae 
brownish; anal brush of abdomen orange. Forewing rather densely strewn with large, yellowish-brown scales, 
and with a brown median and postmedian band which is curved distally convex. Hindwing white, with brownish 
margin and fringes. — In the $ the anal brush is yellowish or brownish, the forewings are less dusted with 
brown and their bands indistinct. Christmas Island. 
P. irrorata Moore. $: white. Forewing with numerous black spots. Antennae, palpi, head and thorax 
light yellow. Base of abdomen white, end brown, anal brush deep yellow. Legs white. Expanse of wings: 
32.6 mm. Java. 
P. gracilior Pag. from the Aru Islands, has an expanse of 19 mm (E), a whitish antennal shaft 
with darker pinnae, thorax, legs, wings and fringes white, the anal angle and posterior margin, however, 
faintly yellowish. Beneath as above, the veins a little darker. [It is perhaps an Euproctis !]. 
P. isabellina Heyl. $. It is said to be closely allied to P. jumosa Sn. (which, however, is said to 
be an Euproctis ), but the forewing without white transverse lines, the discocellular spot smaller, hindwing white 
and beneath without a black dot, thorax with a yellow anal tuft and like the thorax less dark, the whole under 
surface more intensely white, the hindwing even silvery whitish. Expanse of wings: 32 mm. Padang Pandjang, 
Sumatra. 
P. lutea F. (= [Artaxa] chrysospila Wkr., chrysophaea Luc. 1892 nec Wlcr.) (45 d). E- yellow. 
Antennal combs black. Anal brush very long. Fore wing with two white, thin, distally curved bands, the first 
of which is antemedian, the other postmedian. Hindwings project beyond abdomen. Expanse of wings: 
24% mm. Varying very much both in size and colouring. In both sexes there is a form with dark-speckled 
hindwings. Cairns, Kuranda, Townsville, Rockhampton, Brisbane, Queensland. — iobrota Meyr. is a form of 
P. lutea, with ferruginous-ochreous forewings, body and extremities; forewings with ochreous undulate trans¬ 
verse lines at % and 2 / 3 of the length of the forewings. Hindwings dark ferruginous. Antennal pinnae black 
(E). •— The $ is in the forewing like dark Erf of lutea, in the hindwing darker brown. E 19 to 24, $ 24 to 
28 mm. Cooktown and Eiunundi in Australia. 
P. paraneura Meyr. Like P. lutea (45 d), but the first line of the forewing is more uniformly curved, 
the second is in the middle sharply angular, in the terminal parts sinuate; in the E there is in the lower half 
before the first and behind the second line one nebulous ferruginous band each; $ of a deeper colouring 
than P. lutea, and the area between the first and second line of the forewing is dorsally usually ferruginous, and 
the lines are very indistinct. E 22 to 23, $ 28 to 40 mm. Fly River, New Guinea. 
P. pyraustis Meyr. E 19 mm. Body and extremities orange; antennal pinnae 8. Forewing triangular 
with an obliquely rounded margin, rather dark ferruginous, in the basal half except along the costa strewn 
with ferruginous-orange hair, costal margin orange like the whole fringes. HindAving dark grey; fringes 
grey with a light ochreous distal margin (apex). Queensland. 
P. radiata B.-Balc. (45 b) ; $: body yellow like the forewing which shows traces of a pale median 
oblique line and of a more distinct similar postmedian line; the spaces between the veins are filled up with 
orange. Hindwings lighter yellow. Expanse of wings: 50 mm. British New Guinea, in July. 
P. squamosa B.-Balc. (45 b). E'- body orange-brown. Forewing light straw-coloured with an orange- 
yelloAV patch at % from the base of the proximal margin; the spaces betAveen the veins are light orange. Hind¬ 
Aving light straw-coloured, at the base and in the middle deeper yellow. $: paler; the spaces between the veins 
of the foreAvings speckled with darker scales. Expanse of wings: E 39, $ 49 mm. British NeAv Guinea, in March- 
April and August, at an altitude of 600 ft. 
P. lutearia B.-Bak. (45 b). body light orange. Forewing orange, at the posterior margin most 
intensely so. Surface of Avings rough. Hindwing chrome-yelloAv. Expanse of wings: 36 mm. Ekeikei, British 
New Guinea, January and February.
