HARPYIA BiLNKSIJE. J 65 



colour is greenish-yellow, each segment with an 

 oblique whitish stripe directed backwards. All the 

 segments have round white spots surrounded with 

 black on the lower parts, and on each side rather 

 above the middle, from the fourth to the eleventh 

 segment inclusively, there is a cluster of three or 

 four round white spots placed on a black ground. 

 The anal segment bears a small black horn, and 

 wants the upper lateral spots. This caterpillar feeds 

 on the Banksia Illcifolia, and when near its trans- 

 formation, it is, to use Lewin's words, of consider- 

 able bulk, very showy, and in general a great de- 

 vourer. He found it change to a pupa in February, 

 spinning on the surface of the earth a slight web or 

 cell, and collecting about it some fragments of earth 

 and leaves in order to disguise it. It remained in 

 this dormant state thirty-six days, and was on the 

 wing in March. The moth occurs in the neigh- 

 bourhood of Sidney.

Many of the families into which the nocturnal 

 Lepidoptera have been divided by authors, however

 treme points of difference, comprise species of so 

 ambiguous a character, that it is not easy to pre-
