148 ME. G. T. BETHUNE-BAKEE : A EBVJSION OE THE 



The male of this species is a beautiful insect, the intense richness and depth of the 

 blue being very striking. I have one specimen from Java, in which the reddish purple 

 of the underside is entirely replaced by a curious subdued steely bronzy green, 

 something like the colour occasionally found in meander "Boisd. 



In de Niceville's collection are two males and one female from Tenasserim, and in 

 Staudinger's collection there is one male from Assam. 



The female has not hitherto been described, but Heir Fruhstorfer has sent me a fine 

 pair from Java for identification and I have described the female sent by him.

I have very carefully examined this species and compared it most particularly with 

 A. adulans described by de Niceville at the same time, and I cannot believe that they 

 are other than one and the same species. The main differences stated by him are that 

 the latter is darker and less reddish, and lacks the small costal spot over and beyond the 

 third cell-spot. Now I find that in all species that have a reddish, or a reddish tinged 

 with lilac or violet, underside, the colour is very liable to vary, and except in very fresh 

 specimens the lilac or violet colour is apt to ev r anesce and leave a merely reddish hue 

 behind ; then as to the lack of the costal spot, in one of de Niceville's specimens of adala 

 there is a very small spot present on the costa of one wing, and I have noticed in this 

 group of insects that this particular spot seems given to occasional disappearance. 



This species is very close indeed to arvina Hew., and will come next to it, indeed so 

 close is it that on first examination I quite thought it was the female of that species, 

 but closer inspection revealed that some of the specimens were males.

3 . Upperside : both wings pale azure-blue ; primaries with a broad black costa, 

 broader outer margin, and yet broader apical area; secondaries with very broad margins 

 all round, the costa being rather the broadest. Tail short, fairly stout, tipped with 

 white; at the end of the cell in the primaries is a distinct black spot invading the 

 blue. Beneath both wings fairly dark purplish lilac, with rather darker spots tinged 

 with red. The pattern is just the same as in adala de Niceville, except that there is a 

 distinct bend in the first four spots of the transverse band of the primaries and a very 

 slight fracture below the fourth spot ; there is also a slight trace of some submetallic 

 scales at the anal angle.
