AMBLYPODIA GROUP OP THE LYC^NIM. 85 



I have before me one specimen from Pulo Laut in which the brown surface below is 

 quite lustrous and the markings of the primaries are much more distinct. 



This species is nearest aroa Hew., but can be recognised immediately by the 

 exceptionally dark blue of the upper surface, in which it differs from all its near allies. 



Arhopala sceva, n. sp. 



Hah. Sumatra. 



Expanse, 6 & S , 40 mm. 



6 . Upperside : both wings purple of a reddish tint, in a side light having a 

 brownish shade ; primaries with a narrow brown costa and outer margin ; secondaries 

 with a broad brown costa and narrow outer margin ; the lower median nervule is 

 elongated into a distinct tooth, but apparently there is no tail. Underside : both 

 wings warm greyish brown with darker spots palely ench'cled. Primaries with three 

 increasing cell-spots ; below the second and third are two smaller ones divided by the 

 lower median nervule ; transverse band composed of six spots with a detached one 

 below the sixth in the submedian area ; first spot small and round, second, third, and 

 fourth each shifted beyond its predecessor and increasing in size, of a broadish oval 

 shape, fifth spot of same shape shifted inwards, sixth inclined slightly outwards, and 

 below this the seventh detached spot already referred to; submarginal row very 

 obscure. Secondaries with four basal spots, second and fourth shifted slightly 

 inwards, followed by three large spots below each other, of which the second and 

 third touch ; cell closed by a largish spot, below which is a very small one in the lower 

 median angle ; transverse band composed of eight spots, the second shifted well 

 outwards, third and fourth confluent, shifted well outwards again, fifth narrow, wedge- 

 shaped, shifted inwards, sixth outwards, seventh and eighth confluent and shifted 

 right inwards ; submarginal row less obscure than in the primaries ; anal spot deep 

 black, preceded by two others, more or less covered with metallic bluish or greenish 

 scales. 



$ . Upperside : both wings violet ; primaries with broad brown costa, broader 

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

 round. Underside as in male. 



This species has a very distinct underside ; the spots are prominent and the transverse 

 bands have an unusual look difficult to describe, especially in the primaries, in which 

 the spots are of a broad flattened oval shape.
