PoLYTHYSANA, Felder. 



30. Polijthysaiia ruhrescens. 



Attacusrubrescens, Blanchard, in Gay's 'Chili,' 7, p. 60; 

 pi. 4, fig. 3 (1854). 



Six males. 



" Common in the forests of Vaklivi'a, but very difficult 

 to take ; the males fly about the tops of the trees, in the 

 sunshine between the hours 12.30 and 2 p.m. only ; the 

 females are nocturnal ; larva unknown to me ; on the 

 wing in February and March." — T. E. 



81. Polythysana edonondsii, n. s. 



(? . Very near to P. andromeda, Philippi, but with 

 the outer border of primaries snow-white internally, 

 instead of being uniform with the rest of the wing ; 

 primaries above chiefly differing from P. ruhrescens in the 

 same character, but with the ocellus rounded ; secondaries 

 carmine, the interno-basal area and a band from just 

 before the middle of the abdominal border to the costa 

 black ; abdominal half of disc and external border bright 

 orange, with brown outer margin ; the external border 

 bounded internally with black, and touching the ocellus, 

 which is of a deep crimson-lake colour, broadly bordered 

 with black, and enclosing a white lunule ; body as in P. 

 ruhrescens ; under surface bright golden orange ; the 

 internal areas of all the wings and the costal area of 

 secondaries washed with rose-red ; ocellus of primaries 

 black, with lake-red centre, enclosmg a white pupil ; the 

 black internal edging widened into a broad almost 

 ^-shaped band ; the snow-white patches as above ; 

 secondaries with the ocellus reduced to a minute lake- 

 red oval spot, with white central line ; internal boundary 

 of external border silvery grey, with slender blackish 

 inner edge, mixed with lake-red scales ; outer margin 

 and fringe ash-grey. Expanse of wings, 80 mm. 



5 . Considerably larger than the male and with its 

 pattern, but with the general coloration of Saturnia 

 boisduralii ; the brilliant colouring is confined to the 

 ocelli of secondaries, the ground tint of these wings 

 being pale flesh-coloured, with the external half of the 

 disc up to the inner edge of the external area olive-brown. 

 Expanse of wings, 110 mm. 



One pair.
