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). 



Ha gen as macareus, Godardt [sic] ; and macareus, var. xanthosoma. 

 Staudinger as macareus; and maccareus [sic], var. xanthosoma. Occurs 

 throughout the year in the plains (Selesseh aud 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 Bohorok. We have never seen a female. 

 The male may be a mimic of Danais vulgaris, Butler, or, as it has a 

 deep yellow abdomen, of Danais banksii, 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. 



611. Papilio {Paranticopsis) leucothoe, Westwood. 



P. leucothoe, Westwood, var. interjectus, Hourath, Berl. Ent. Zeitsch., vol. xxxvii, 

 p. 490 (1S93). 



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 Bekantschan ; 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 Eaphea. Rothschild records it from Sumatra as (b), 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 lai'ge 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 Bohorok
