The gynandromorphous specimen here ligured has been kindly lent to 

 me by Mr. Paul Mowis, by whose native collectors it was obtained in 

 Sikkim. It is not of the usual bilateral form, but the markings of the 

 wiufs are more or less commingled. Each wing may be thus described: — • 

 The forewing on the left-hand side is mostly feminine, and is larger than 

 that on the right-hand side ; on its upperside it is normally marked, 

 except that there is a short male orange streak at about the middle of 

 the costa on either side of the b:ise of the first subcostal nervule, but 

 more anterior than posterior to that vein ; (in the underside this wing is 

 wholly feminine, except a narrow streak of the male yellow coloration 

 along the basal two-thirds of the costa. The hindwing on the left-hand 

 side is mostly masculine, wholly so on the upperside, and is smaller than 

 the opposite wing ; on the underside, however, the usual uniform male 

 yellow coloration is broken by a wide discal streak of the sexual feminine 

 white coloration, which commences narrowly at the base of the vv'ing, 

 occupies the posterior half of the discoidal cell, and ends widely near the 

 outer margin. The forewing on the right-hand side is mostly masculine, 

 but the basal anterior quarter of the wing has the normal feminine 

 powdery-black coloration, and there are feminine white streaks invading 

 the masculine orange area ; on the underside the coloration is about two- 

 thirds masculine and one-third feminine, there being a very broad band 

 of feminine (white) coloration extending completely across the wing 

 from the b:ise to the outer margin on the anterior half of the wing. 

 The hindwing on the right-hand side is mostly feminine, on the 

 upperside it boars a male narrow discal yellow streak, commenc- 

 ing at the base of the wing in the discoidal cell, broken before the end 

 of the cell, reapi)earing again in the discoidal intorsj)ace for a short 

 distance at its middle, and placed against that vein ; on the underside 

 the anterior third of the wing has the ground-colour masculine 

 (yellow), while the posterior two-thirds has it feminine (white).
