specimen of this species, for which I have accordingly retained 

 the name. The tiueformosa is best known by the narrower fore- 

 wings, yellower markings, which also differ in detail, and especially 

 by the rouud white spot on the fold, which in Orac. ida, forms 

 part of a dorsal streak. A widely distributed species, but almost 

 always taken singly, without any clue to its habits ; occurs at 

 Sydney, Parramatta, and Bulli, and also near Brisbane and 

 Melbourne, from October to March without apparent interruption, 

 usually in thick bush.
