528 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 
610. Papilio ( Paranticopsis ) xanthosoma, Staudinger. 
P. maccareus [sic], Godart, var. xanthosoma, Staudinger, Iris, vol. ii, p. 7 (1889). 
Hagen as macareus , Godardt [sic] ; and macareus , var. xanthosoma. 
Staudinger as macareus ; and maccareus [sic], var. xanthosoma. Occurs 
throughout the year in the plains (Selesseh and Paya Bakong), on the 
outer hills, and as far south as Soengei Batoe, also in the Gayoe terri¬ 
tory ; most abundant in November, March and April. In November, 
1894, two Malay collectors brought in 104 male specimens collected in 
six days from Kepras near Boliorok. We have never seen a female. 
The male may be a mimic of Dana is vulgaris , Butler, or, as it has a 
deep yellow abdomen, of Danais hanksii, Moore. They fly exactly like 
a Danais , but betray themselves to the collector by coming to wet spots 
on roads, which Danais seldom do ; also when settled they keep their 
wings in constant motion, whereas a Danais always rests with folded 
motionless wings. Rothschild records this species from Sumatra as (c), 
P. macareus xanthosoma , Staudinger. 
61J. Papilio ( Paranticopsis ) leucothoe, Westwood. 
P. leucothoe , Westwood, var. interjectus , Honrath, Berl. Ent. Zeitsch., vol. xxxvii, 
p. 490 (1893). 
Hagen as leucothoe ; and leucothoe , var, interjectus. Distant. Stau¬ 
dinger. A variable species as regards the extent of the white markings 
in all the localities where it is found. Occurs in the forests of the 
plains (Selesseh), and outer hills (Namoe Oekor), not much higher 
than Bekantsclian; also in Asahan and Indragiri.' Rather rare in 
February and March, aud again in September. Its habits on the wing 
are similar to those of P. butleri , Janson. It is doubtless a good mimic 
of a brown Euploea. Rothschild records it from Sumatra as (6), P. leu¬ 
cothoe interjectus , Honrath. 
612. Papilio ( Paranticopsis ) delessertii, Guerin. 
Grose Smith. Hagen as laodocus. The P. delessertii of Guerin 
described originally from Pulo-Pinang, has priority over P. laodocus , 
De Haan, by one year. The butterfly is a beautiful mimic of 
Ideopsis daos , Boisduval. The female is paler than the male, from which 
it may instantly be known by the two spots beyond the discoidal cell 
bisected by the lower discoidal and third median nervules in the 
forewing being fused into a large quadrate patch. Found throughout 
the year in the plains and outer hills, most abundant from February 
to April, Dr. Martin took it himself near Paya Bakong not far from 
the sea. Very common on the western boundary of our area at Boliorok
