very wide ; tlie anterior pair of spots of the discal series continued to 

 the costa ; the margin bears three interrupted series of spots. Sind- 

 iving with a costal band at the base of the wing; an obscure grey 

 fascia posterior to this ; the discal band very narrow on the abdominal 

 margin, very broad on the costa ; followed by a grey line ; the spots of 

 the submarginal band wider and more lunular than above ; two prominent 

 marginal lines, the outer the wider. 



It is difficult to say to what group N. niscea belongs. The discal 

 band of the forewing being divided into three pairs of spots allies it 

 to the N. cohcmella group, the pure white markings and general fades 

 ally it to the N. nata group. It is also near to N. nandina, Moore, 

 orio-inally described from Java and Darjeeling, but the middle pair of 

 spots of the discal series on the forewing being conjoined instead of 

 well separated will immediately differentiate between the two species. 

 On the whole it appears to be nearest to N. pampanga, Felder, from 

 N.-W. Luzon, as figured in Herr Greorg Semper's " Schmett. der 

 Philippinischen Inseln," pi. xxix, figs. 6, male ; 7, female, from which 

 it may instantly be known by the discal band of the hind wing on the 

 underside being half the width at the point where it touches the 

 abdominal margin that it is in that species. 



Described from two examples received from Herr H. Fruhstorfer, 



7. Argynnis niphe, Linnaeus, Plate III, Figs. 1 and 2. 



The gynandromorphous example of A. niphe, Linnasus, here figured 

 was reared by Mrs. S. Robson at Bankipur, Behar, Northern India, 

 and emerged from the pupa on the 2nd March, 1893. It is thus refer- 

 red to* by that lady in describing her experiments in breeding this 

 species : — " One lusus ^laturce, a male, had one wing as in the ordinary 

 male, and the other as in the ordinary female ! " 



This insect has the right-hand pair of wings masculine, the left- 

 hand pair feminine. In the masculine half of the insect there is, 

 however, in the forewing on the upperside a slight admixture of femi- 

 nine coloration, the round black spot in the lower discoidal interspace 

 in the outer discal series of spots has a streak of white on either side 

 of it, and on the disc are many irregular blue-black streaks more or less 

 connecting the black spots. The hindwing is quite normal. On the 

 underside of the masculine forewing there is the commencement of a 

 well-defined white subapical band as in a normal female example, and 

 the discal black spots have, as on the upperside, some irregular blue- 

 black markings attached to them. The hindwing on the underside is 

 quite normal. The feminine pair of wings are smaller than the mascu-
