FOUR NEW SPECIES OF ARROPALA. 

 BY G. T. BETHUNE-BAKER, F.L.S. 



Arhopala sangiea, n sp. 



cj . Upper-xide : primaries exceedingly pale silvery-blue, almost as pale as 

 argentea, Stgr., bluer towards the outer margins, ■with a subtriangular apical patch 

 of rich, deep, dark purple; costa very narrowly black, outer margin broadly black, de- 

 creasing in width very rapidly from the second median nervule. Fringes black, tipped 

 ■with white from the second median nervule. Secondaries very pale, beautiful slightly 

 silvery-blue, losing the silvery tint beyond the extremity of the cell. Costa greyish 

 to the subcostal nervule, outer margin very finely black. Tail, at the end of the 

 third median nervule, rather long, black, tipped ■with white, on each side of which 

 is a small blackish marginal spot. Fringes black tipped ■with ■white, abdominal fold 

 ■whitish. Underside dark greyish-brown, with all the spots and fascise broadly 

 marked out with white, as follows : primaries, a fine short white line from base to 

 the second cell spot, three large increasing cell spots, over the second and third are 

 smaller spots up to the costa, all these spots are bordered broadly laterally with 

 white, so as to appear more fasciae than spots, the transverse fascia very irregular, 

 the first small spot beginning very near the third cell spot, the second shifted 

 outwards, third and fourth confluent, shifted still further out, fifth right inwards, 

 its outer lateral edging being almost confluent with the inner edging of the fourth 

 spot, and its inner edging being practically confluent with the outer edge of the 

 third cell spot, sixth spot shifted yet further in, with its inner white border pro- 

 jected right inwards to the second cell spot ; submarginal fascia continuous, very 

 distinct from the costa to the inner margin, rather broadly edged with white, and 

 following the line exactly of the wing margin ; outer margin bordered with white, 

 very finely intersected by the nervules ; subdiseoidal area with a whitish patch in 

 the middle ; submedian area white, with a brown central spot. Secondaries with a 

 short white streak over the costal vein, extending about a third along the costa. 

 Four basal spots, none completely encircled, the upper three touching each other, 

 the fourth shifted inwards, being hook-shaped, and touching the last spot of the 

 transverse fascia, these are followed by three spots below each other across the centre 

 of the cell, cell closed by a large quadrate spot, laterally edged, below which the 

 usual one is marked by a long white dash extending nearly to the transverse fascia, 

 which is very irregular, the first spot having its inner edge confluent with that 

 of the second spot, which is also confluent with the outer edge of the quadrate cell 

 spot, second spot larger, with its outer edge shifted outwards, third and fourth spots 

 shifted right outwards and confluent, the inner edge touching the outer edge of the 

 previous spot, fifth shifted inwards, sixth slightly inwards, but inclined rather 

 outwards, seventh angular spot shifted right inwards, quite dislocated, and confluent 

 with the eighth long spot, which forms as it were a long extension of it ; submarginal 

 fascia distinct, broadly bordered with white ; marginal line white ; lobe spot and 

 one on each side of tail velvety-black, the middle one being almost obliterated by 

 very pale silvery-blue metallic scales, the other two edged above by the same 

 coloured scales. Expanse, (J , 44 mm.
