AMBLYP0D1A GROUP OF THE LYC.1NID.P. 41 



as I can trace, appears to be confined to Ceylon and the South Andaman Isles, though 

 a specimen I have from Nias comes very close to it. 



The genitalia of all these are indistinguishable from each other, and they also are 

 exceedingly close to A. micnlc Blanch. ; the tegumen of centaurus is not so large and 

 the clasps less excised at the extremities.

6 . Upperside : both wings dull violet ; primaries with the costa and outer margin 

 very narrowly brown ; secondaries with the costa widely and the outer margin very 

 narrowly brown ; abdominal fold grey. Tail longish, very broad, black, tipped with 

 white; nervures on each side slightly elongated, so as to form very short tooth-like 

 projections. Lobe moderately well developed. Underside : both wings dull, very pale 

 brownish grey, uniform in tint, with darker spots palely encircled. Primaries with 

 three increasing cell-spots, the third quadrate; below the second and third are two 

 large spots divided by the lower median nervule ; transverse band composed of six 

 confluent spots, forming an almost straight fascia of equal width placed somewhat 

 obliquely outwards ; below the band is a seventh spot shifted inwards ; marginal and 

 submarginal bands very obscure. Secondaries with four basal spots, the lowest shifted 

 inwards, followed by three smallish spots below each other ; cell closed by a narrow 

 subquadrate spot, below which is a small one ; transverse band highly irregular and 

 peculiar, composed of two large spots below each other which touch the narrow sub- 

 quadrate spot, below this and shifted outwards is a broad irregular fascia occupying the 

 place of spots 3-6 inclusive, the seventh angular spot is shifted inwards and is almost 

 confluent with the eighth long spot ; marginal and submarginal fascia very obscure : 

 anal lobe blackish, edged above, and the space between it and the second median 

 nervule tilled in, with bluish metallic scales. 



2 . Upperside : both wings bright pale shining blue, darker towards the edges ; 

 primaries with the costa broadly blackish, increasing towards the apex, where there is 

 a large blackish patch and the outer margin is very broadly blackish ; secondaries with 

 the costa very broadly dark brown and the outer margin narrowly so, but increasing 

 somewhat towards the anal angle. Underside as in the male. 



This species is evidently the Australian form of centaurus Fab. The colour above 

 is duller and paler and the dark outer margin is of a width intermediate between that 

 of that species and of pirithous Moore. On the underside the colour is very much paler 

 and is altogether more uniform in tone, the pattern is smaller in the primaries, there 

 is no metallic edge to the cell-spots, and in the secondaries the lobe is mon
