422 Elwes & de Niceville — List of the Lepidopterous [No. 5, 



H. marathus, Doubleday and Hewitson, and we do not yet know whether 

 it is constantly distinct from the typical form. 



Penthbma darlisa, Moore. 



*49. Parthenos gambrisius, var. lilacinus. 



Papilio gambrisius, FabriciuiS, Mant. Ins., vol. ii, p. 12, n. 113 (1787). 



Parthenos lilacinus, Butler, Trans. Linn. Soc, Zoology, second series, vol. i, p. 

 544 (1877). 



P. apicalis, Moore, Proc. Zool. Soc. Lond., 1878, p. 829. 



Two males from Ponsekai of the varietal form lilacinus, showing 

 no approach to the other varietal form apicalis described by Mr. Moore. 



50. Hypolimnas bolina. 



Papilio holina, Linnaeus, Syst. Nat., ed. x, p. 479, n. 124 (1758). 

 A pair from Tavoy and Ponsekai. 



51. YOMA VASUKI. 



r. vasulci, Doherty, Journ. A. S. B., vol. Iv, pt. 2, p. 259, n. 9 (1886). 

 A single male from Sinbyoodine of this beautif al species. 



52. Rhinopalpa polynioe. 



Papilio polynice, Cramer, Pap. Ex., vol. iii, pi. cxcv, figs. D, E, male (1779). 

 One male from Tavoy. If B. fulva, Felder, is hereafter proved to be 

 distinct from U. polynice, the species in question may be called by the 

 former name. 



53. Cethosia biblis. 



Papilio hihlis, Drury, 111. Ex. Ins., vol. i, pi. iv, fig. 2, male (1770). 

 One male from Ponsekai. 



54. EuRiPUS halttherses. 



E. halitherses, Doubleday and Hewitson, Gen. Diurn. Lep., vol. ii, p. 293, n. 1, pi. 

 xli, fig. 2, male (1850). 



Hestina isa, Moore, Horsfield and Moore, Cat. Lep. Mus. E. I. C, vol. i, p. 161, 

 n. dSd, female (1857). 



Euripus euploeoides, Felder, Eeise Novara, Lep., vol. iii, p. 415, n. 638 (1866) ; id., 

 Distant, Rhop. Malay., p. 134, n. i, pi. xiii, fig. 6, mule ; 7, female (1883). 



One female from Tavoy agrees perfectly with Distant's figure, and 

 almost exactly with the commonest though extremely variable form of 

 the female of this species occurring in Sikkim which Mr. Moore des- 

 cribed as a distinct species under the name of E. isa. Mr. Distant, after 

 devoting nearly a page to a description of this form, ends by saying that 

 E. euplaoides is clearly a local race of E. halitherses, but we cannot allow 

 this to be the case, as it is not peculiar to any one region or locality. A 

 local race is a race which is limited in its range, whilst this seems to be 

 merely an inconstant variety in the female sex.
