A LIST OF THE BUTTERFLIES OF BORNEO. 165 
(i) hind-wing underside markings composed of black lnes 
enclosing white areas 
= continental race, mooret boisduvali. 
(11) hind-wing underside markings deep black 
= insular race, moorei mooret. 
boisduvalui var. atra, Druce, I take to be a variety of the in- 
sular race moorei mooret, characterised by an orange discal 
patch on upperside of fore-wing. ‘This is nicely demonstrated 
by a long series of males and females in the Sarawak Museum, 
im which the prominent orange discal patch of var. atra becomes 
smaller and smaller reaching the final stage of obsolescence in 
typical moorei. The undersides are exactly similar in all 
specimens male and female. 
If this view is correct, this species affords a parallet case of 
variation to that of Biduanda thesmia, (see p. 162). 
Injuries. (1) ¢, anal angle of right hind-wing bitten off. 
(11) 8, small symmetrical bite across the anal angle of hind- 
wings removing both tails.
