592. Papilio ( Euploeopsis ) penomimus, Martin. 
P. penomimus, Martin, Einige neue Tagsclmietterlinge von Nordost-Sumatra 
(Munich), pt. 1, p. 2, n. 2 (1895). 
This butterfly, though it has the facies of the species included in 
the dissimilis group (subgenus Chilasa ), may belong to the paradoxa 
group (subgenus Buplceopsis) , as it has the hindwing at the termination 
of the upper subcostal nervule produced, that being a characteristic 
feature of the species of the latter group. P. penomimus reminds one 
somewhat of P. ramaceus , Westwood, Trans. Ent. Soc. Lond., 1872, 
p. 95, pi. v, fig. 3, from Borneo, which species, however, is placed by 
Rothschild under P. leucothoe, Westwood. It is very rare in the forests 
of the plains and on the outer hills, occurs near Selesseh, at Bekantschan, 
and at Bandar Quala in Serdang from January to March and again in June. 
Dr. Martin bred it from some larvee found by Herr 0. Puttfarcken 
at Bandar Quala in Serdang in May, 1894. They feed on a low shrub 
in the forest called by the Malays “ Dahoen Laksah,” are velvety green 
and deep indigo blue, with round lateral red spots, and short fleshy 
tubercles. The pupa is similar to that of P. butleri , Janson, being sus¬ 
pended by a black girth to a stalk of the food-plant, the three posterior 
abdominal segments greatly flattened on the side touching the stick. 
As the stalk was still green, the pupa also was mostly green with 
brown and white markings. The imago emerged in 16 days. 
From what I can gather from Mr. Rothschild’s paper on Papilios, 
the three last named species all belong to P.paradoxus, Zinken-Sommer, 
sub-species telesicles , Felder. Mr. Rothschild’s collection appears to 
contain only three males and one female of the group from Sumatra, 
of which he enumerates the female as P. paradoxus telesicles , Felder, 
(r 2 ), 9-ab. daja, Rothschild. He does not say what his males are. 
When he wrote his paper Dr. Martin’s description of both sexes of 
P. penomimus had not reached him. Dr. Martin writes to me that 
after examining Dr. Staudinger’s collection at Dresden, he considers 
that the three species we have enumerated above are all one, and that 
in Sumatra it is trimorpliic in the female. What he has described as 
the male of P. penomimus is an error, all his specimens of that species 
being females. Rothschild names Distant’s figure in Rhop. Malay., pi. 
xxviia, fig. 6, male “ (w*), ab. distanti” ; and Distant’s figure pi. xxvii, 
fig. 6, female , “ ( u *), ab. nepticula.” As regards P. tenigma , Wallace, 
Rothschild records it as “ (g 8 ), c? -ab. enigma, Wallace.”
