through the centre of a band of the ground colour ; 
the subdorsal lines are also white, as are also the 
broad spiracular lines, and there is another finer 
white line between the dorsal and subdorsal ones; 
segmental divisions yellowish; the spiracles very 
minute, black; ventral surface green, longitudinally 
striped with numerous very fine darker lines. 
Changes to pupa below the surface of the ground. 
The pupa is three-eighths of an inch long, rather 
stout, but tapering sharply towards the anal segment, 
which finishes with a fine point; the eye-, lee-, and 
wing-cases prominent ; colour dark mahogany-brown. 
Part of the imagos emerged in the middle of the 
following month (August), but most remained over 
the winter, appearing as moths at the end of May and 
beginning of June, 1876. (George T. Porritt, 10th

Plate CXXI, fig. 7. 
A captured moth Jaid me some eggs on the 10th of 
May of this summer (1864). 
The eges were at first pale straw-coloured, soon 
turned bright red, and afterwards became dingy. 
The larvae hatched on the 28th of May, and fed 
throughout most freely on common fern (Pieris 
aquilina) ; they rested at full length, but when dis- 
turbed twisted into knots and jumped about angrily ; 
they went to earth during the last week in June. 
The larve assimilate well in appearance to their 
food-plant, and must be hard to detect; when full- 
fed their length is rather over an inch, shape cylin- 
drical, and of uniform size throughout, except that 
the segmental folds look contracted, and the head is 
rather flattened. The ground colour is olive-green, 
the belly paler, more olive-grey ; some individuals had 
a slight reddish tint. At first sight the whole larva
