EIJOPALOCERA MALAY AN A. 



Male, Besembling P, esperi, but the under surface of the posterior wings hairing a more or less 

 distinct double row of marginal spots, the innermost being bounded by bluish luuules. 



Female- Resembling P. esperi, but the anterior wings having the white subapical fascia absent and 

 transferred to the inner marginal area ; posterior wings having the reddish anal -angular patch larger than 

 in P. esperi t und containing a dark spot. Wings beneath as in P. esperi, but with the corresponding 

 differences aB above.

These lost five species ? or varieties? here described ami figured exhibit in a marked 

 degree the gradual transference of the male characteristics to the female sex. /\ wjenor, ? , 

 and 1\ pfucniz, £ , show the strongest sexual divergence, whilst P. cilix, S t P. esperi, ? , and 

 P. mestor, 9 , more closely, — and in the order named,— approach the hue and markings of the 

 male,

Male, Differing principally from the same a ex of the preceding species? or forms described by 

 having the red anal-angular patch on the under surface of the posterior wlaga much more restricted. 



Female, Anterior wings above resembling those of P. phoenix, ?, but somewhat paler; posterior 

 wings caudately produced, creamy white, the neuration (broadly), a basal patch occupying nearly half of 

 cell, a broad submarginal fascia,— widest and terminating at the median nervules, — anal angle and a 

 spot above it on abdominal margin, and the caudate appendages, black; a patch on abdominal margin 

 (containing the black spot), two marginal lnnulate spots divided by the median nervules, and sometimes 

 more obscure marginal lunulate spots extending to apex, reddish ; fringe of both wings greyish. Wings 

 beneath as above, the posterior wings with red basal spots, Pronotum and bead black ; abdomen above 

 yellowtsh'grey, with a dorsal blackish fascia ; body beneath and legs fuscous or black.

The question whether this is merely another female form of P. agenor requires solution. 

 Evidence in favour of its being so is found in the statement of Wallace,! that in a closely 

 allied species, P. memnon, I " the males, the tailed and tailless females, have all been bred from 

 a single group of the larvse by Messrs. Payen and Bo ear me in Java," 



♦ Aa proposed by Mr. Butler. The under surface of the posterior wings only given- 

 t Trans. Linn. Soc, vol. xxv. p. 0 (1805). 



I P. memnon is closely allied to P. agenor, and represents the insular species, whilst P. agenor is the continental form.
