AMBLYPODIA GEOUP OF THE LYCLENUm 43 



is not subject to such violent contrasts as in that insect, the tone being much more 

 uniform and the pattern more compact. Hewitson pointed out that the fourth spot 

 of the transverse band of the primaries was projected outwards; this, however, is not 

 always so. I have specimens from Sumba, Timor, and the Babber Islands, and in each 

 of these the band is unbroken, though for all my specimens from the mainland and 

 from Ceylon his remark is correct; the anal lobe, moreover, is always very much more 

 developed and is deep velvety black beneath. I have seen no specimen from the 

 Andaman Isles. De Niceville says (I. c.) that he has seen one which is smaller and in 

 which the area of the blue coloration of the upperside is different (does this mean 

 the specimen was a female 1 ?), and all the markings below are smaller, more compact, 

 and prominent. This specimen is not among those Mr. de Niceville kindly lent me, so 

 I can only record his note. 



[Since writing the foregoing note on the Sumba, Timor, and Babber specimens, I have 

 very carefully re-examined them, and am inclined to regard them as a transit from 

 this species to araxes Felder ; the upperside colour is almost the colour of amantes, 

 but the underside pattern is that of Felder's insect. The range of true amantes will 

 therefore be restricted to the mainlands and the Andaman Isles, the Makassar specimens 

 I believe to be the transition form. In the genitalia the clasps assume a sub triangular 

 form, whilst the base of the penis is angular instead of being almost straight.]

•5 . Upperside : both wings brilliant morpho-blue, shading into purplish near the 

 margins, in the costal, apical, and posterior marginal areas, costa itself finely black, 

 posterior margin less narrow. Secondaries : costa broadly blackish, posterior margin 

 narrowly black, abdominal fold grey. Underside : both wings pale brown, with darkish 

 spots with pale margins. Primaries with three discal spots increasing in size, all 

 margined with bluish or silvery white except on their costal edges ; below the spot 

 closing the cell is a triangular spot, touching the inner edge of which is a large spot in 

 the paler submedian area followed by another near the base ; transverse fascia ending 

 on or below the lower median nervule and consisting of six, seven, or eight confluent 

 spots regularly below each other with a slight outward tendency, the seventh and 

 eighth sometimes detached ; submarginal row indistinct ; the ground between these 

 two latter fasciae is greyish. Secondaries more uniform in colour with four basal spots, 

 the second shifted slightly, and the fourth considerably inwards, the latter beyond but 

 touching the internal nervure ; outside these are two large spots below each other; cell
