Butterflies from the Andaman Islands. 357 



transparent, brown-white, palest below the median nervure : 

 the margins, the base (which is marked by a triangular carmine 

 spot), longitudinal rays in the cell, the nervures, and lines 

 between them dark brown. Posterior wing marked before 

 the middle by five white spots — one (the largest) in the cell, 

 one between it and the costal margin, two between it and the 

 inner margin, and one (the fifth) below the cell : the inner 

 margin, which is marked by a black spot, and a series of six 

 spots on the outer margin all dull carmine : the outer margin 

 dentate, deeply sinuated between the nervures ; the tail spatu- 

 late, its outer half white, tinted with carmine. 



Underside as above, except that the posterior wing has four 

 red spots at the base and seven white spots before the middle. 



Exp. 5 inches. 



This singular species, although reminding one at first sight 

 of P. Coon, is so like P. Memnon (var. Achates, Cramer) that 

 but for the long and narrow posterior wing it might easily be 

 mistaken for that species. 



Neptis Cnacalis. 



Uppersicle dark brown. Anterior wing with the longitu- 

 dinal spot from the base orange, unusually long, reaching con- 

 siderably below the middle of the wing, unbroken : crossed 

 beyond the middle by six spots of orange, the middle two 

 spots minute, and outside of this by a narrow band of lilac- 

 white. Posterior wing crossed before the middle by a broad 

 band of white. 



Underside. Anterior wing as above, except that the band 

 and spots are much larger and rufous white, the apex grey- 

 white, and that there are some grey spots near the costal 

 margin. Posterior wing with the base brown, undulated with 

 grey: below the band lilac-grey, traversed by two bands of 

 brown ; the outer margin brown. 



Exp. 144 inch. 



On the underside this species resembles N. Hordonia ; its 

 anterior wing is unusually prolonged at the apex. 



Adolias Acontius. 



Upperside. Female dark rufous brown. Anterior wing 

 with the usual spots in the cell : crossed from the middle of 

 the costal margin to a little beyond the first median nervulc 

 (towards the anal angle) by a band (broader as it proceeds) of 

 seven white spots — the first minute, the last, which is below 

 the median nervule, small : a band of three spots, commencing 

 nearer the apex, joins the band just described at its fourth
