pair extend from the costa and posteriorly coalesce Avith the discal pair 

 which are as irregular and dislocated as in the fore wing ; terminal mark- 

 ings similar to those on the fore wing : but the double subterminal series 

 of dark spots more lunular and a prominent round black subterminal spot 

 crowned with ochraceous in interspace 2. Antennte. head, thorax and 

 abdomen dark brown ; the shafts of the antennre speckled with white ; 

 beneath : the palpi fringed with black, thorax dark greyish-brown, abdo- 

 men white. Female. U^^perside : brownish purple, sometimes fuscous. 

 Fore and hind wings : as in the male with anticillary dark lines, but difi'er 

 as follows : — fore wing : an iridescent bluish sheen from base outwards to 

 disc ; hind wing : a slender more or less prominent white line edging the 

 anticiiiary black line on the inner side, a subterminal geminate double 

 black spot in interspace 1 and a similar larger single spot in interspace 2. 

 Underside : ground-colour paler and brighter than in the male, the mark- 

 ings similar but more neatly and generally more clearly defined ; both fore 

 and hind wings in most of the specimens that I have seen with a Avhite 

 terminal line before the anticiiiary dark line. Antennte, head, thorax and 

 abdomen much as in the male. Expanse : male and female, 20-25 mm. 



This is a variable insect both in the shade of the groiuid- colour and in exact 

 shape and disposition of the markings as is pointed out by Colonel Bin- 

 gham. He says " In females from the Andamans, the ground-colour on the 

 underside of the wings seems always to be a rich, golden ochraceous. I 

 have also seen specimens of the female from Continental India, Assam 

 and Burma, with the ground-colour of the same shade. The markings on 

 the undersides of these specimens are always narrower, neater, more 

 clearly defined ; and the pairs of white lines, instead of being edged on 

 the inner sides of each pair by fuscous are margined by black lines. Also 

 certain specimens from Sikkim. from Ceylon and from the Andamans 

 resemble very closely, both in ground-colour and in markings of the under- 

 side, the figure of A^ nora, Felder, on plate xxxiv, fig. 34 of the 'Novora 

 Reise' volume on the Lepidoptera. 1 believe Felder's species is simply a 

 variety of A'', ardatesy As for the form N. noreia, Moore, cle Niceville 

 says : " Of all these, the only one that presents any difficulty in identifica- 

 tion is A", noreia. That species has no tail, aiid I have always consider- 

 ed it to be a dimorphic form in both sexes of A', ardates, Moore." From 

 breeding in Kanara, Bombay, the " rich golden ochraceous " colour of 

 the underside seem to be due to heavy rainfall and is always confined to 

 the female. 



Eyy. — TnTh&n-shaped. The surface covered all over with reticulations 

 forming cells, the walls moderately broad and high, especially just at the 

 change between the fiat, somewhat depressed top surface to the perpendi- 

 cular sides where the intersections are thickened and prominently raised 

 into little round-topped prominences which are erect, slightly flattened 

 above and below and shining ; these prominences lose themselves towards 

 the base as well as very soon after they get over the rim on to the fiat top ; 

 the highest prominences are quite the height of one cell diameter where 

 they are ; the largest cell is just over the rim on the side of which it takes 

 up, indeed, most of the height — the cells in this particular row are all 

 hexagonal and from each knob or intersection-prominence radiate thin 

 lays to the intersections surrounding it ; all the other cells are, nearly 

 without exception, more quadrangular and decrease in size from the brim 

 to the centre of the top, but not rapidly, those around the central, irre- 

 gular, low-walled surface containing the micropyie being 7 or 8 in number 

 and somewhat distorted, the smallest of all ; the rows of cells are arranged 

 more or less — this is not quite regular — either in wide sweeping curves, all 

 having their origin at the micropyie theoretically and curving out like
