had been thus given some years before by E. Doubleday in an 

 unpublished British Museum List. O. idmo appears as a noraen 

 nudum in ' The Genera.' Mr. Miskin does not appear to have 

 noticed this, for in this Society's Proceedings (1890, p. 24) he says 

 that specimens of both sexes of 0. orontas are in the Australian 

 Museum. I have very carefully examined the specimens in the 

 Australian Museum without finding any but females of 0. idmo, 

 and a male identical with Hewitson's figure of 0. orontas. Mr. 

 J. J. Walker has caught this species in West Australia, other- 

 wise it is known from South Australia and Victoria. 

 Exp. $ 26 mm., 9 27 mm. ($ 2, 9 1). 



Ogyris otanes, Felder.

In shape the male is like a small male of 0. (jenoveva, with 

 scarcely so long an anal projection; colour above brown, with a 

 very faint purplish reflection; the female has the yellowish patch 

 just beyond cell on f orewing, and centrobasal areas purplish. On 

 the underside the markings are obscure except those of cell of 

 forewing. My specimens are in very poor condition, but Felder's 

 figures are excellent. Miskin was quite wrong in supposing that 

 this was a southern form of (>. (jeiioveva. I most certainly agree 

 with Lower who says that Tepper's 0. halmaturia comprises 0. 

 otanes $ and 0. idmo ^. 



Loc. — South Australia and Kangaroo Island.
