HAIiPYIA BANKSIJE. 
165 
colour is greenish-yellow, each segment with an 
oblique whitish stripe directed backwards. All the 
segments have round white spots surrounded with 
hlack 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 hlack ground. 
The anal segment bears a small black horn, and 
wants the upper lateral spots. This caterpillar feeds 
on the Banksia Ilicifolia, and when near its trans- 
formation, it is, to use Lewin’s words, of consider- 
able hulk, 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. 
ARCTIIDiE. 
Many of the families into which the nocturnal 
Lepidoptera have been divided by authors, however 
distinct they may appear when viewed at their ex- 
treme points of difference, comprise species of so 
ambiguous a character, that it is not easy to pre-
