44 ME. G. T. BETHUNE-BAKEE : A EEVISION OE THE 



closed by a quadrate spot, below which is a small triangular one ; transverse fascia 

 consisting of the following spots — two large upper almost confluent ones, two others 

 below shifted outwards, fifth spot small, shifted inwards a little, sixth very slightly 

 outwards, the angular seventh spot well inwards and almost confluent with a long 

 eighth spot which touches the internal nervure ; submarginal row very indistinct ; 

 anal spot black, over which are scattered metallic-blue scales, as also over the marginal 

 area up to the second median nervule, and these have an internal edging of dark brown 

 bordered with white and following the course of the transverse fascia up to the 

 internal nervure. 



The second median nervure is elongated a little, so as to form a short tail beyond the 

 white-tipped longish one. 



? . Upperside : both wings rich dark brown ; the primaries with a bright pale blue 

 patch on the lower half of the wing, extending two-thirds along the inner margin, 

 while in the secondaries this blue patch extends almost to the posterior margin 

 below the lower discoidal nervure. Underside as in male. 



This species is very close to amantes, but may be distinguished from it at once by 

 the very brilliant morpho-blue of the male, Hewitson's insect being very much darker ; 

 whilst in the female of Felder's species the blue is very much less in extent, is not 

 lustrous, and is paler. Felder also points out another distinguishing character, viz. 

 that the transverse band of the primaries is straight and not broken as in amantes Hew. 

 Araxes is also decidedly the larger insect of the two. I have specimens of it before 

 me from S. Celebes, N. Celebes (Minahassa), Banka Isle, and Mangioli, Sula Isles, 

 but I cannot trace it elsewhere, so that its distribution appears to be very confined 

 and local.

6 . Upperside : both wings deep blue with a slight mixture of purple with narrow 

 black borders, the costa of the secondaries is rather broadly black. Abdominal fold 

 up to the submedian nervure brown. The submedian nervure and the second median 

 nervule is each elongated a little, so as to form a very short tail on each side the 

 usual tail. Underside : both wings brown, paler on the primaries below the lower 

 median nervule, all the spots very slightly darker brown and margined with whitish. 

 Primaries with three largish discal spots increasing in size ; below the spot closing the 

 cell is another small one, and below that a third larger spot occupying the terminal
