108 MR. G. T. BETHUNE-BAKER : A REVISION OF THE 



edged. Primaries with three increasing discal spots ; below the second and third are 

 two others divided by the lower median nervule, and above the third is a very small one 

 on the costa ; transverse fascia irregular, first spot small, second and third confluent, 

 inclined outwards, fourth shifted well outwards, fifth and sixth confluent and shifted 

 right inwards, but not detached, seventh shifted slightly inwards and oblique, 

 sometimes quite small ; submarginal row distinct, but with obscure margins ; submedian 

 area slightly paler. Secondaries with an obscure spot at the costal base ; four basal 

 spots, the fourth shifted inwards on to the inner margin, followed by three spots below 

 each other ; cell closed by a longish narrow spot, beneath which is a small triangular 

 one; transverse fascia composed of eight spots, the second larger than the first and 

 touching the upper outer extremity of the narrow spot closing the cell, third spot 

 shifted right outwards but not detached, fourth further out, fifth inwards, sixth outwards, 

 seventh angular spot inwards and touching the eighth long one ; submarginal row 

 rather obscure ; lobe-spot black ; a small black spot is also between the second and 

 lower median nervules, the space between and over which is filled with bluish or 

 greenish-metallic scales. 



2 . Exactly like the male, except that the green is replaced by a violet-blue patch 

 on the upperside of both wings, and the underside is somewhat lighter. 



This species was originally described by Horsfield as the female of eumolphus Cram. 

 It can readily be separated from all others of this group, except basiciridis de N., by 

 the green colour being limited to less than two-thirds of the primaries and to less than 

 one-third of the secondaries. It is much closer to de Niceville' s insect, in the description 

 of which species the comparison will be found : horsfieldi appears to be entirely confined 

 to the island of Java, and it is interesting to notice how very local all these green species 

 are with the exception of eumolphus.

c? . Upperside : both wings dark brown, with a bluish-green metallic patch occupying 

 the cell to the upper margin and one-third of the median area of the primaries. In the 

 secondaries this metallic patch extends from just above the cell to the submedian 

 nervule, but scarcely beyond the cell as to the outer margin. Tail brown, white-tipped. 

 Underside : both wings of a warm brown, with slightly darker spots and fascia palely 

 margined. Primaries with three good-sized discal spots increasing in size ; beneath the 

 second and third are two other large spots separated by the lower median nervure, 

 and above the third a small obscure spot ; transverse band irregular, composed of
