Habitat : Stephansort, German New Oruinea. 



Expanse : <?, 2*4 ; ? , 2*5 inches. 



Description : Male. Uppeeside, both wings black, with shining 

 pearly- white markings. Forewing with a short clavate streak towards 

 the base, a quadrate spot at the middle, and a large triangular spot 

 beyond the end of the discoidal cell ; two small outwardly-obliquely- 

 placed subapical spots ; two much larger, the upper the larger of the 

 two, well-separated rounded discal spots divided by the second median 

 nervule; three widely-separated submarginal dots. Hindiving with a 

 broad even-edged discal band, of equal width throughout, occupying 

 seven interspaces, commencing on the inner margin and ending on the 

 subcostal nervure; a submarginal series of five small round spots. 

 Underside, forewing as on the upperside, but the four spots on the disc 

 a little larger ; the submarginal series consisting of six spots. Hindwing 

 with a short streak towards the base of the wing in the subcostal inter- 

 space ; the discal band a little broader than on the upperside, and with 

 a small additional portion in the subcostal interspace ; an obsolete series 

 of elongated spots between the discal band and the submarginal series 

 of spots ; the latter consisting of eight spots, which are larger than on 

 the upperside. Female. Upperside, forewing differs from the male in 

 the submarginal series of spots being six in number instead of three. 

 Hindwing has the discal band extended by an additional portion in the 

 subcostal interspace in one specimen, but not in the other ; the posterior 

 edge of the discal band irregular, in the male it is even. Underside, 

 forewing as in the male. Hindwing with the additional portion of the 

 discal band in the subcostal interspace much larger than in the male. 



N. nausicaa differs from N. lactaria, Butler, in the forewing in 

 having the two discal spots divided by the second median nervule much 

 smaller and consequently well separated, in N. lactaria they are con- 

 joined ; in the hindwing in having the discal band of the same width 

 throughout and reaching the abdominal margin, in N. lactaria
