130 J. N. ELIOT 



Ph. fissizonata viridens ssp. n. 



(PI. 2, fig. 20) 



$ smaller than the preceding subspecies, with fore wing length 30 mm. On the upper surface 

 the markings are pale green of a deeper shade than ever occurs in other forms of the amphion 

 complex. On the fore wing the cell streak is reduced to a single small green spot at cell-end 

 (as in Ph. amphion), but the streak beyond cell is only a little smaller than in ssp. fissizonata ; 

 the postdiscal markings are as in fissizonata, but the submarginal series is prominent and 

 irregular, the part below vein 4 being inclined inwards and the spot in space 6 slightly shifted in. 

 On the hind wing the discal band is outwardly slightly concave and the veins crossing it are 

 blackened, though not nearly so heavily as in the preceding subspecies ; the postdiscal band is 

 obsolete except for a small green spot in space 5. The under surface is entirely different to the 

 preceding subspecies, showing an unexpected reversion to the pattern of Ph. shepherdi. The 

 ground colour is pale brown, with the base of the forewing costa pale buff. The fore wing cell 

 streak is rather weakly indicated and is divided in the middle. On the hind wing the discal 

 band ends on vein 6 ; the postdiscal band consists of narrow crescents and in spaces 3 and 4 

 there are darker brown blotches between the discal and postdiscal bands, which are continued 

 distad by brown shading along vein 4 into the outer part of space 3, exactly as in shepherdi. 



Holotype $. Solomon Is. : San Christoval, iv-v.1908 (A. S. Meek). One other 

 female with same data. 



The subspecies is strikingly different from those found in the rest of the Solomon 

 Is., and the resemblance on the under surface to the forms of the complex found in 

 New Guinea and N.E. Australia suggests that San Christoval has undergone a 

 prolonged period of isolation from the rest of the group during which an ancestral 

 form has been able to survive with little change. The subspecies is possibly worthy 

 of species rank. There are no examples in BMNH from the large and little-known 

 island of Malaita ; it is conceivable that a form linking viridens with the other 

 subspecies may be found there.

Judging by the male genitalia the two species in the genus are not closely related 

 to one another.
