The female approaches, according to Martin's descriiition (I.e.), ratlier nuu-h 

 the preceding species; both sexes are, however, easil\- distinguishable from P. Iconpsaca.t 

 by the red mark at the base of the hindwings beneath. The hindwings of the male 

 are rather variable in pattern, and sometimes without any spots above, as in P. acheron 

 Grose Smith, which Hagen (I.e.) calls a melanistic variety of P. fmhesl. 



Like the females of P. lam.psacas Boisd. and P. memnon L., the female o( forbe-si 

 has at the base of the forewings above often a triangular patch.

S. Differs from P. forbesi Grose Smith especially in tlie huffish area of the 

 underside of tlie hindwings being much restricted, and in tlie forewings lieing 

 darker. 



S . Unknown. 



Hah. North Borneo: JMount Kina Balu (6 6), Mount .AIulu (3 S ). 



If P. acheron, which is still scanty in collections, turns out to be as variable as 

 P. forbesi, it will be difficult to draw a i)arting line between the two insects.
