edge sharply defined and curved slightly outwards ; anteriorly the band 

 reaches the middle of cellule 4, and posteriorly the inner margin where 

 it is most yellow in colour. 



Underside fuscous-black. Fore wing fuscous in the apical and 

 distal area. Band as above but sea-shell pink (xiv). Two white dots 

 at apex in cellules (5 and 7. Hind wing band sea-shell pink, anteriorly 

 limited by vein 4, edges sharply defined ; distal and posterior part of 

 band with orange spots on the veins, a streak on the submedian, and 

 along the inner margin. Two white apical dots in 4 and 5. A sub- 

 marginal row of five white dots, two in lc and others in 2, 3 and 4. 



Head fuscous-black ; a white line round the eye, broken above ; 

 a white dot at base of antenna, on the inside ; palpi orange ; antenna 

 black. Thorax chestnut-brown above, black beneath. Legs fuscous- 

 black above, except fore legs, which have the femur and tibia orange. 

 Abdomen chestnut above and laterally, orange-yellow ventrally. 



2 . Upperside with fuscous-black ground-colour, and white bands. 

 Fore wing with band broader than in the 3 , entering lower angle of 

 cell and not reaching the submedian, its edges sharply defined but 

 irregular, the part below vein 2 with inner edge more distal than in 

 the other. Hind wing with broader band than in the 3 , somewhat 

 as in eromena, but entering cell to beyond vein 2, and anteriorly 

 narrowing to beyond vein 5, with either a spot reaching vein 6, or some 

 white scaling in cellule 5 ; a slight yellow tinge on the outer edge 

 of the band in cellule lb. 



Underside with ground-colour as in 3 ■ Fore wing band a little 

 broader. Two white dots in 4 and 5, just within the pale distal shade, 

 a white dot in 6 near the margin. Hind wing band as above ; white 

 dots as in the 3 but larger, and another white dot in 3 joined to the 

 edge of the band. 



Fore legs with femur and tibia slightly tinged with yellow-brown. 

 Abdomen fuscous, ventral surface white tinged with yellow. 



Length of fore wing : ^,25 mm. ; 2 , 28 mm. 



Wanggar Eiver, 15 miles from coast, ca. 600 feet, January to 

 February, five 3 3 , seven 2 2 ; Nomnagihe, 2,000 feet, January to 

 February, four 3 3 , six 2 2 . 



P. poultoni was found flying with the Agaristid Imrnetalia saturata 

 longipalpis Kirsch. This species has a white-banded 3 and an orange- 

 banded 2 . 



A note on this mimetic association is contributed by Professor 

 Poulton to the present volume. 



The 2 of P. poultoni was found feeding on tree gum.
