only slight varieties of the same species. Kirby's inclusion of 

 Hewitson's 0. Otrontas with 0. Idmo is either a misprint or mis- 

 take, and intended, it seems to me, for 0. Otane><, as 0. Otrontas 

 is without the large pale spot in the forewings of the female, 

 which is so conspicuous and characteristic a mark in both the 

 others. For the same reasons the latter have no connection with 

 my 0. halmaturia, and Mr. Lower's distribution of the sexes is 

 entirely fanciful. I have observed 0. Otanes (identified by the 

 Hon. AV. McLeay) at N'uriootpa numerously for several seasons 

 from 1873 to 1889, and of 0. Idmo, Hew., is a pair in the 

 Museum (presented by the late Mr. McDougall) from Southern 

 Yorke's Peninsula. Having seen the sexes repeatedly in coitu 

 at the former locality, I should think myself capable of dis- 

 tinguishing them. But at Nuriootpa I have never observed any 

 females without the pale spot, or at Kangaroo Island any sj^otted 

 ones, although for several days keenly on the hunt ; but often 

 had the opportunity of seeing the males attend or chase the un- 

 spotted females in the neighbourhood of Queenscliffe. The 

 Kangaroo Island species, my 0. hahnaturla, ditiers also from 

 Idmo-Otanes in coarser and more distant scales, besides form and 

 colour. 



Unless, tlierefore, 0. Jiahnaturia be identical with 0. Otrontas, 

 Hew., which I still doubt, not having seen specimens of the latter, 

 I regard it as a good sp(>cies on account of accurate oljservations 

 in the field. The Port Lincoln specimens belong most likely also 

 to 0. halmaturia.

From a careful study in the field, and a comparison of figures 

 and descriptions, it appears to me that both these names refer to 

 the same species. I had the opportunity for observing these 

 butterflies on several occasions at Coromby, Victoria, where they 

 were rather numerous, and frequenting all sorts of culti\'ated 

 plants and flowers in the bright sunshine, both sexes being inter- 

 mixed (i.e , both " species "), and attending each other promis- 

 cuously. On the other hand I received the same forms from 

 Southern Yorke's Peninsula, caught in the same locality, and by 

 the same person. The female "^?>irt?'y//i.??" is distinguished by 

 red bars on the underside of the forewings from all other species, 

 and is so figured by Hewitson and Angas. The male " Oraetes^ 

 figured by Hewitson, is always found attending the former, lience 

 the conclusion that both are the sexes of one species. The 

 difference of the colouring of the upper side of the females is 

 due to abrasion or its absence, and then more or less hyaline or 

 opaque. The female being the more characteristically marked,
