*122. Papilio (Euploeopsis, subg. no v., de Niceville) telearchus. 

 P. telearchus, Hewitson, Trans. Ent. Soo. Lond., new series, vol. ii, p. 22, pi. vi 

 fig. 3(1852). 



Three males of this fine species from Tavoy, and one from Ponse- 

 kai. P. butleri, Janson, figured in Distant's ' Rhopalocera Malayana,' 

 pis. xxvii, xxviia, is a near ally of this. 



123. Papilio (Menamopsis, subg. nov., de NicevilleJ tavotanus. 

 P. tavoyanus, Butler, Ann. and Mag. of Nat, Hist., fifth series, vol. x, p. 373, n. 3 

 (Nov., 1882). 



P. clarce, Marshall, Journ. A. S. B., vol. Ii, pt. 2, p. 42, n. 7, pi. iv, fig. 5, male 

 (Dec, 1882). 



Through an accident and from no fault whatever of Major Mar- 

 shall's, Mr. Butler's name for this species has priority of publication. 

 Major Marshall's paper describing it and other Tenasserim species was 

 written and read many months (nearly a year) before Mr. Butler's 

 paper appeared. 



One male from Ponsekai. 



Papilio (Paranticopsis) xenocles, Doubleday. 



*124. Papilio (Paranticopsis') megarus. 

 P. megarus, Westwood, Arc. Ent., vol. ii, p. 98, pi. Ixxii, fig. 2 (1845). 

 Many males from Ponsekai and the hills. 



125. Papilio {Paranticopsis) macareus. 

 P. macareus, Godart, Enc. Meth., vol. ix, p. 76, n. 144 (1819). 



Many males from the hills and Ponsekai. They are much smaller 

 than Bornean specimens, and have less white in the interspaces of the 

 hindwing than those from Sikkim. 



*126. Papilio (Ghilasa) onpape. 

 P. onpape, Moore, Proc. Zool. Soc. Lond., 1878, p. 840. 



Several males from Tavoy, Ponsekai, and the hills. They vary 

 considerably in the amount of white on the fore wing, which is usually 

 more abundant in Tenasserim than in Indian specimens. At best this 

 species is only a local race of P. panope, Linngeus, which itself is a varia- 

 ble and probably dimorphic species.
