the same insect as that which has hitherto been termed 

 Auge or Lasinassa, with which the detailed description 

 in Mus. Ludovicae Ulricge perfectly agrees, while it will 

 not at all apply to the Bolina of Cramer. This error 

 originated with Cramer, who quotes Linngeus and Clerck 

 for his Pajnlio Bolina, which is a different insect, to 

 which it will now be necessary to apply the name of 

 Misippus, given to the female by Linnaeus. Cramer^s 

 mistake has been unfortunately adopted by all succeed- 

 ing authors, who seem never to have compared the two 

 insects with the original description and figure. The 

 alteration at this late period will, therefore, cause much 

 confusion, but unless the law of priority is abandoned, 

 no other course is open to me. 



This is an exceedingly wide-spread and variable 

 species. The male is tolerably constant, but presents 

 three decided modifications. That which extends over 

 the whole continent of India, is generally distinguished 

 by a row of white points behind the blue and white spot 

 on the hind-wing, and the white bands across the wings 

 on the underside are well marked. Those of the Malayan 

 and Polynesian countries never have the white dots, and 

 seldom have the bands beneath so distinctly marked. 

 Clerck^s figure closely resembles an Indian specimen 

 without the white dots. Cramer's figures represent the 

 two most common Malayan forms of the male insect. 

 Papilio Auge is the most abundant, and with it are 

 associated females of the type of his P. Iphigenia. 

 Papilio Lasinassa is a larger insect, in which the blue 

 gloss completely covers the white spots, the margins are 

 less deeply scallopped and less distinctly spotted with 

 white, while on the underside the white transverse bands 

 are nearly or quite absent, and the submarginal lunules 

 are larger, deeper, and placed closer to the submarginal 

 line. The large dusky and yellow-banded females, such 

 as P. Manlia, P. Eriphile, &c., seem to belong to this 

 form, which is most commonly met with in the Moluccas 

 and the Pacific Islands. The most common females of 

 the Indian form (P. Perimele, Cram. 67, B.) are also very 

 distinct looking insects. In the British Museum are 

 some remarkable specimens from the Philippine Islands, 

 in which the male has the spot on the hind-wings reduced 

 to a mere blue gloss without any paler centre, so that in 

 most lights it is invisible; but without a large series
