Indian form, Avith which I hare compared specimens; 

 our species is a somewhat variable insect. 



Mr. Masters is doubtless correct in sinking the name 

 Scottianus (Feld.), considering it a synonym of Mac- 

 leayanus. 



Xuthus (Lin.). — I think this insect must be permitted 

 to remain on the list of Australian butterflies, however 

 improbable the chances of its having been taken in Aus- 

 tralia may appear. In the Cat. Pap. B. Museum a spe- 

 cimen contained in the national collection is authori- 

 tatively announced as from Port Essington. 



Dissimilis (Lin.) — This is another species given as 

 Australian in the Cat. Pap. B. M. p. 71, of which Mr. 

 Masters makes no mention. Whether it is a reliable 

 Australian species or not I am imable to say, but, like 

 many others reputed as Australian, of which perhaps 

 casvial or accidental specimens only have been taken, or 

 others which have been caught elsewhere and described as 

 Australian in error — of Avhich cases have occurred — they 

 must remain, at any rate provisionally, in the list of 

 Australian insects until more reliable and authentic infor- 

 mation concerning them can be procured. 



In the subfamily Pierin(R INIr. Masters ignores the 

 genera Tachyris (Wall.) and Delias (Hiib.), ■v\'ithout 

 giving any reason ; why, I cannot understand, as these 

 genera appear quite sufficiently distinguished by the dif- 

 ference in the neuration of wings. 



In the genus Terras, Mr. Masters includes Hecabe (Lin.) 

 and Sari (Horsf.) as distinct species; there can be no 

 doubt that the latter is the Australian form oi Hecahe, and 

 differs very little, if at all, from that well-kno-vyn insect. 



Two species in this subfamily quoted by Kirby appear 

 to have been overlooked by Mr. Masters, viz. — 



Delias Fragalactea (But!.), (Thyc. F.), Ann. Nat; 

 Hist. ser. iv. voL iv. p. 243 (1869). 



Pieris JavcB (Sparrm.).— (Pap. J.), Amoen. Acad. vu. 

 p. 504, note 1 (1767). The $ appears to have been 

 described by Donovan, under the name of Pap. DeiopeiUi 

 in his Ins. N. Holland, t. 21, f 2 (1805). . 



Fam. DANAID^. 

 Genus Danais (Latr.). 

 Mr. Masters expresses surprise that in Kirby's work 

 D. affinis is treated, as he says, as a synonym or var. of
