amaryllis, but the uppersides are different. It is also a variable 

 species, northern forms being lighter and larger. 



In .Spry and Anderson's ' Victorian Butterflies ' this species is 

 figured under the name of 0. amaryllis. 



It is by far the commonest of the three species, and I have 

 specimens from all the Australian States but Tasmania. It is in 

 both sexes somewhat like 0. ormtes on the upperside, and like 0. 

 amaryllis on the underside. The recognition marks may l^e 

 taken as the irregular discal band on the underside of the fore- 

 wing; and the pale silvery-blue colour. 



Great confusion has been caused regarding the three silvery- 

 blue species mainly through want of sufficient material. All 

 three species are from Queensland. 0. orcetes appears to be 

 confined to that State. 0. amaryllis ranges into the Xorthern 

 Rivers of New South Wales; while 0. hewitsoni is found all 

 through Australia. Miskin's great mistake was in failing to 

 recognise that it was only the females that had scarlet in the cell 

 on the underside of the fore wing, and thus making his 0. 

 amaryllis consist of the female of 0. hewitsoni as the male, and 

 the true 0. amaryllis as the female. Likewise he made 0. orcetes 

 comprise two different males. It is curious to note that the 

 underside of the hindwing is almost the same in the three species 

 except in the intensity of the brown colouration.

/J. Upperside. Forewing with costa convex, apex acute; 

 outer margin straight, slightly concave in the middle ; inner 

 margin straight : between costa and subcostal nervure a dark 

 margin, grey at base, and then black to the apex, where it is 

 widest ; outer margin black, about the same width as costal 

 margin; a prolongation of the black costal margin downwards 

 occurs at the end of cell; a few pale blue scales are sprinkled on 

 the black costal margin near the apex; the rest of the wing is 

 pale silvery-blue; where the nervules approach the black outer
