25. G. virescens buruensis Rothsch., subsp. nov. 



(? ? . A very large form, resembling G. pavonina, described by Dohrn from 

 Sumatra. 



Wings above. Forewing : outer margin concave ; greenish black, veins in 



outer half pale greenish olive buff. Hindwing : azure blue, faintly shot with 



green, base black for the greater part, this colonr forming an ill-defined streak 

 in cell along M ; disc with indications of black patches between veins, patch 

 M' — M- distinct in S, outer margin much less rounded than in virescens reducta 

 and V. virescens, almost straight in 6 . 



Underside. Forewing : black, veins blue, except SC - ' ; outer half of 



cellule SM'— SM- pale azure blue. Hindwing : cell black, middle line blue, 



costal margin black, except distally ; abdominal area black in basal half, this 

 colonr extending more distad between than upon the veins ; rest of wing blue, but 

 there are three large black discal patches between R^ and M-. 



Length of forewing : cJ, 41mm; ?,44mm.

26. G. virescens celebensis Rothsch., subsp. nov. 



(S ? . Wings above resembling buruensis in colour, shorter, hindwing more 

 rounded ; hindwing black from base to apex of cell, mesial line of cell and outer 

 third of wing blue, four black patches between R' and M- separated from each 

 other by the rather thin bine veins, and limited basally by the blue cross-veins. 



Underside purplish black. Forewing : basal two-thirds of costal margiu, 



outer part of cell-vein and snbcostals thinly, veins R' — M- broadly, glaucous blue ; 



outer half of cellule SM' — SM- also glaucous blue. Hindwing : outer marginal 



area glaucous blue, somewhat creamy at veins R" to M', the blue colour extending 

 proximad along veins, separating two patches from the purplish black basi-discal 

 area, a third patch between M' and M- not completely isolated, the base of vein 

 M^ and partition M' — M- of M not being blue ; cross-veins blue ; mesial line of 

 cell very thinly blue ; the blue scaling in abdominal area restricted to outer margin, 

 but extending down a little along veins. 



Length of forewing : t?, 33 mm ; ? , 31 — 38 mm. 



Hab. S. Celebes, August, September 1891 (W. Doherty), 1 S {type), 1 ? ;

 black scales instead of red. Forewing: ashy grey, paler towards the apex and
