grey r;itl)er lluin ihe brown of M. iyaita, and the nielallic mar- 

 gins of llic coloured spots are much inoro conspicuous. 



M. chri/sovof,ii,s (){ OvosG Smith (" Rhopalocera Ivxolica, ' 1899, 

 pi. xlix.) described from a single female from Cooktown, is, in our 

 opinion, but a slight variety of M. Ujidta ; we have a female from 

 Cc'pe York and another from Kuranda, but no niale has yet been 

 taken, and that sex is needed to proveord is i)rove its identity 

 with the typical M. iynila. 



'I'ypical M. uftiiia, according to the original description by 

 Leach, has portions of the veins of the hind-wing marked with 

 copper. 'I'he types came from the neighbourhood of Sydney, 

 and the usual Sydney form is thus marked, though specimens 

 will) the c.o|)per absent are by no means uncommon in New 

 South Wales and Victoria. 



M. olliljl is evidently inleiulcd by Miskin to apply to that form 

 of M. iijvita in which the coppery markings of veins are absent, 

 but the locality of the type is unfortunately uncertain — " Newcastle, 

 N.S.W., and Fremantle, \V. A." The probable type (a male) is 

 still in the Australian .Museum, but is without a locality label ; 

 above it is of a slightly different shade of purple, has more clearly 

 defined dark margins, and has an obscure bluish tornal jKitch on 

 the hind-wing ; beneath the ground colour is different, the S|)Ots 

 are narrower, and the s])Ot between veins (> and 7 of the hind- 

 wing is much nearer the tern)en ; but the position of this spot is 

 by no means constant in .)/. Ignita. Pending further material 

 from Western Australia we think it best to consider this specimen 

 an individual aberration of J/, ignita. 



We have a male and ii female from Brisbane that differ hom 

 typical M. ignita in being very highly coloured beneath. From 

 Mackay we have two females much larger than, but otherwise 

 ahnosl identical with, J/, eri/thrina, but here again we need 

 the male to confirm our opinion. I'Vom Mackay we have a male, 

 and from Sandgate a female, for which, in the absence of further 

 examples, we hesitate to claim specific rank ; they have the pale 

 spots beneath very narrow, and the coloured sub-terminal band 

 of lore-wing beneath is on the inner instead of the outer side of 

 the sub-terminal interrupted line of metallic spots ; they form a 

 connecting link between the ])ur|)l(' .1/. i(/n.it<i and the bronze 

 piuple .J/, '■inriiriis. 



tiiioi.oc.icAL Mai' of Victoria. — .\ new geological map of 

 Victoria, on the scale of 16 miles to 1 inch, has just been issued 

 by the Mines Department, at the nominal price of one shilling. 

 Owing to the adoption of a larger scale, it has been possible to 

 include more details than hitherto, hence the usefulness of the 

 map is greatly increased.
