244 Mr. W. H. Mlskin's Note on a 



D. Plexippus ; it is true that affinis is quoted as a van 

 of this latter species, but Mr. Masters appears not to have 

 observed that in the appendix to Kirby's work the error 

 is rectified. 



Mr. Masters is wrong in making Chrysippus and Petilia 

 distinct species ; they are one and the same. Petilia ( StoU. ), 

 the Australian form of this world-wide species, differs but 

 little from its congeners of other countries, but appears to 

 me to assimilate more closely to the Afi-ican form, with 

 which it agrees in the almost total absence of the row of 

 marginal white spots on the posterior wing ; this charac- 

 teristic seems most prominent in the Mauritius form, where 

 we see the white spots distinctly and perfectly developed. 



Our insect, described by Macleay under the name of 

 Hamata, is sufficiently constant in its smaller size and 

 slight difference of mai'kings to be retained as a variety 

 of the Indian insect it so nearly approaches, but it appears 

 to me, on comparison, to resemble more closely Cramer's 

 Melissa, than Limniace. 



In the genus Ewplo^a Mr. Masters is again abroad : 

 Angasii (Feld.) and Corinna (Macl.), given by him as 

 distinct species^ are both undoubted synonyms of E. Syl- 

 vester (Fab.). 



E. Hyems (Butl.) gives precedence to Felder's name, 

 Arishe, the latter having priority of date.* See App. 

 Kirby's Cat. 



Acraa Theodote (WaUen). — I think Mr. Masters is 

 right in his remarks respecting this insect ; it is certainly 

 a mythical species. 



Cethosia. — Another species should be added, viz., Cyane 

 (Dru.), var. Penthesilea (Cram.), upon the authority of 

 Mr. Macleay (King's Surv. Aust. p. 463). 



Messaras. — I think our species is Madestes (Hew.), 

 not Maonites. 



Pyrameis Cardui. — Our form is sufficiently distinct 

 from the European to be at any rate considered a var. ; I 

 think, therefore, that Prof. M' Coy's name of Kershawii 

 should hold good. 



Diadema.~T\iQve are undoubtedly but two Australian 

 species, both perfectly distinct : the one, Alimena (Lin.), 

 varymg but little in its individuals, if at all, and confined 

 to the northern parts of the colony; the other varying in 

 the g only (of w hich there are three tolerably constant
