116 A LIST OF THE BUTTERFLIES OF BORNEO. 
Col. Bingham, “until extensive breeding experiments are under- 
taken it ‘will be impossible to attain any certainty as to whether 
there are two or a dozen distinct forms.” In treating the Indian 
species, this authority divides them into two species only, and | 
have endeavoured to treat the Bornean forms in a similar way. 
Col. Bingham separates the two species thus :— 
A. 692. Underside fore-wing: discal and subterminal mark- 
ings or bands parallel, not anteriorly conyergent = C. 
thetis, 
B. ¢@. Underside fore-wing: discal and subterminal mark- 
ings or bands anteriorly convergent = C, bulis. 
366. Guretis thetis, Drury. 
Papilio thetis, Drury, Ill. Exot. Ent, a1, p: DG; qlee eece: 
Oy 4, g (773) 
Papilio phaedrus, Fabr. Sp. Ins.a. p. 125 (1 7eite 
Curetis saronis, Moore, Proc. Zool. Soc. Lond. p, 587 
(alain) 
Curetis glariosa, Moore, op. cit. p. 522, pl. 48, fig. 1, ¢ 
(1883). 
Curetis arcuata, Moore, op. cit.. p. 523, pl. 48,. fig. 3 
(1883). 
form (a) tagalica, Feld. 
Anops tagalica, Feld. Reise Novara, Lep. ii. p. 221, pl. 
XXVIII. figs. 19, 20 (1865). 
Labuan (Low); Banguey Island (Waterstradt). 
I have not seen an example of tagalica, Feld. but H. H. 
Druce writes:—* C. tagalica is scarcely distinguishable from 
C. phaedrus, Fab., on the upperside, but on the ‘underside Bor- 
nean specimens are usually very strongly suffused with blackish 
brown.” 
Then Bingham says:—*“ C. phaedrus, Fabr., varies so little 
from thetis as to be scarcely ranked even as a variety.” So 
C’, tagalica may be regarded as a form only, of thetis. 
form (b) nesophila, Feld. 
Phaedra nesophila, Feld. Wien. Ent. Mon. VI. p. 289 
(1862). 
Curetis barsine, Druce (nec Feld.), Proc. Zool. Soe. Lond.

(Low, Waterstradt and Wahnes) ; Lawas, Trusan, Limbang, 
Baram, Banting, Santubong, Kuching, Satap, Quop (Sar. 
Mus.).
