the base of the wing to the inner subterminal, transverse, lunular 

 white line. $ . Does not seem to differ from the $ of the typical 

 form. Still other specimens, the difference in which may be due 

 to locality or season (I have not been able to examine a sufficient 

 number of dated and exactly localized specimens to make certain) 

 seem to be intermediate between typical macropliihalma and 

 typical kerriana, Distant. These specimens differ from macro- 

 plithalma as follows : <$ . Upperside : anticiliary black lines on 

 both fore and hind wings distinctly broader, more pronounced. 

 Underside : transverse white lines on both fore and hind wings 

 much broader with a tendency to become diffuse and shift inwards 

 or outwards and thus change the pattern ; this is especially con- 

 spicuous on the hind wings of some of the specimens where the 

 typical pattern is altogether confused and lost by the presence of 

 additional short lunular white lines, and the shifting obliquely 

 inwards or outwards of some of the lines that make up the typical 

 pattern. There is, however, no abrupt change, intermediate 

 specimens seem to link the most aberrant with the typical. Some 

 of the specimens before me show also a tendency to the development 

 of transverse series of dark subterminal spots on the underside of 

 the fore wing as in N. kerriana, Distant. $ . Similar to the $ 

 of the typical form but on the upperside the iridescent blue at the 

 base of the wings changes gradually to whitish on the disc and 

 beyond the apex of cell. Underside : with broad transverse white 

 lines as in the male varieties.

j . Upperside : pale violet ; in one specimen with white spots 

 in the cell and on the disc of the fore wing, and on the hind wing 

 with a white bar on either side of the discocellulars and a trans- 

 verse, ill-defined, discal series of elongate white spots that increase 

 in length anteriorly till in interspace 6 the white occupies the 

 whole of the basal half. Tore wing : costa and termen evenly 

 edged with dark brown, slightly broader at the apex of wing. 

 Hind wing: costal margin dusky ; a transverse, anteriorly ill-defined, 

 subterminal series of dark brown spots and a distinct comparatively 

 broad auticiliary line of the same colour. Underside : very pale 

 greyish brown. Fore wing : a very broad transverse vertical 

 discal bar extended from vein 1 to vein 7 ; a much shorter bar on 

 the inner side of the discocellulars and another postdiscally 

 extended between veins 3 and 7 ; terminal margin broadly white, 

 transversely traversed by two parallel rows of linear spots ; 

 finally, a very prominent anticiliary black line. Hind wing : so 

 very densely crossed by more or less coalescent white bars as to 

 reduce the ground-colour to a series of transverse, irregular, 

 greyish-brown striga? on a white background ; terminal markings 

 consist as on the fore wing of a double parallel transverse
