54 NEW SPECIES OF AUSTRALIAN RUOPALOCERA, 



fuscous-grey, the rest of the wing orange-yellow, with the mark- 

 ings as follows — the oval fuscous spot margined with white 

 near base of cell, a blackish spot margined with electric blue in 

 the middle of cell, and a similar one at end of cell as in q . The 

 blotches below the cell are not shown. The first series of spots 

 is represented by three blue-margined black spots, and the outer 

 series is faintty visible. 



Posterior wing. — Base of wing and J from liase lilac-fuscous, 

 faintly bordered with white from middle of cell to dorsum, a 

 whitish suffusion on dorsum near anal angle. The rest of wing 

 fuscous, mottled with fuscous-black, termen within the cilia marked 

 with a black line, fuscous-black at termination of the veins, 

 slightly lighter between them. 



Loc. — Como, near Sydney, N.S.W.; seven specimens (g 6: Ql, 

 which is probably undersized); in February and March. Types 

 in author's collection. The insects were all caught flying round 

 the tops of small Eucalypts, about 16 feet from the ground. 



The sexes of this insect correspond to one another in the same 

 way as do those of 0. abrota. The purple of the upper side of 

 0. abrota (<£) is replaced by the Morpho-blue of 0. ianthis, (£), 

 and the dark margin is narrower in 0. abrota (£). The pale 

 round spot of 0. abrota (£) is represented by an oval orange-yellow 

 in 0. ianthis (9). The termen of the posterior wing is more 

 serrated in 0. abrota. The underside of these two species is quite 

 different. 



The upper surface of 0. ianthis (g) in colour is allied to (). 

 amaryllis (£), but the latter has narrower dark borders. 



The underside is much nearer to that of 0. otanes than any 

 of the other species, but is generally darker in colour.
