STUDIES ON INDO-AUSTRALIAN LEPIDOPTERA II. J1

97. P. sylvia tigrina Voll. — 64 cf cf and 99 Kloofbivak Jan., Febr. and March 1913 ; 

 Bivakeiland Febr. and March 191 3; locality? 15 Sept. 19 12. cf and 9 Coll. Baggelaar. Ail 

 the spécimens belong to the form tigrina, first described by Mr. Snellen van VOLLENHOVEN 

 from Salawati and figured in „Tijdschr. v. Ent." IX, pi. 10 fig. 2. The figure in ^Seitz" is 

 not that of the typical form of tigrina Voll., because the colour from the cells to the margins 

 must be much darker, like in the race pardalis Fruhst. The yellow colour in the two big 

 circumcellular spots is not présent; thèse spots are pure white or faintly greenish blue. The 

 number of the subcostal spots varies from two to three. The female spécimens of tigrina 

 generally are not so dark as the cf cf and resemble more the figure in „Seitz", but the 

 yellow colour in the spots is not présent. I hâve also compared the spécimens from Central 

 Xew Guinea with the type in the Leyden Muséum of Natural History. Minetra tigrina Voll. 

 is not a species, but belongs to P. sylvia Cram., because there are no spécifie anatomical 

 différences. The différences in the copulatory apparatus are local and not spécifie, which may 

 be seen by examining a séries of spécimens from différent localities from Malaka to New 

 Guinea. It is always dangerous to examine only spécimens from Ceylon [P. cyaneus Moore) 

 and from New Guinea, because, in doing so, the différences found, (which certainly exist) 

 between the two races, are to wide asunder and are not connected by a séries of existing 

 intermediate différences.

98. E. aeropus eutychius Fruhst. — 3 cf cf an d 2 99 Beaufort River 12 Nov. 1912; 

 Kloofbivak 29 Nov. 1912 and 18 Febr. 191 3 ; Mr. G. VERSTEEG leg. 17 Nov. 1912. 2 cf cf Coll. 

 Baggelaar. Two female forms are represented, namely ergena Fruhst. and albifera Fruhst. 

 Both the 99 are rnuch larger than the cf cf •

99. D. ninus distinctes Rôb. - - 1 cf Kloofbivak 7 March 191 3; 1 9 Coll. Baggelaar. 

 The spécimen from Kloofbivak is just like the one figured in „Seitz", IX, pi. 114, fig. b2. 

 The female spécimen, collected by Mr. Baggelaar is larger, but with the same pattern.

 Bivakeiland 1 March 1913. 3 cfcf Coll. Baggelaar. The spécimens are ail différent as to the 

 pattern. The three çf cf from N.W. New Guinea do not possess brimstone-coloured spots in 

 the discus of the anterior wings. In two spécimens are to be seen only two subapical small 

 brimstone-coloured spots and a subcostal one near the top of the cell ; this spot is présent 

 in ail the spécimens but differs in width. In one spécimen is a séries of five spots near the
