fully five dozen eggs upon the two plants. The larve commenced 
hatching out on the 13th June, thus remaining only about six days 
in the egg state. | 
Descriptions of the egg and young larva may be worth 
including, as they are stages which may have been overlooked by 
some. 
The ova are deposited singly, and generally on the upper 
surface of the leaves of clover; some were laid upon the stems, 
and a few on the under surface of the leaves, but I believe the 
upper surface of the leaf is the site generally chosen; both the 
eggs I found upon the plants were in that position. They are laid 
erect, and are fairly conspicuous when a few days old from the 
brightness of their colour. The egg is a; of an inch in height, 
and 4 its height in diameter, of an elongated ovate form, both 
ends much attenuated but rounded; it is slightly concave just 
below the summit; there are about twenty longitudinal keels, the 
majority of them running its entire length, a few beginning about 
% below the summit; it is very delicately ribbed transversely by 
about thirty-six in number. When first laid it is of a yellowish 
pearl-white, gradually becoming deeper in colour, approaching 
creamy yellow. When about twenty-four hours old it assumes @ 
light copper-pink hue, from which it gradually deepens into a 
rosy orange-pink, the high lights glistening with blue, the orange 
colouring showing in shadow; both the summit and base are 
tipped with yellow; it retains the beautiful rosy colouring until 
about a day before hatching, when it finally changes to a leaden 
or purplish grey. °* 
The two eggs laid at large hatched on the 11th June. The 
young larva upon emerging consumes the greater part of the 
shell, which is its first meal. It then measures 75 of an inch in 
length, and is pale ochreous or olive-yellow; the head black ; 
both head and body are covered with short club-shaped spiracles, 
the club formation being at the apex; the longest and finest are 
situated on the anal segment, those on the head being extremely, 
short but strongly clubbed. It feeds on the cuticle of the upper 
surface of the leaf. 
From this point I will only briefly give notes, as further 
descriptions would occupy too much space. 
The first moult took place.on the 21st June, making the first 
stage to be ten days, which probably was of longer duration than 
is usual, as the weather became dull and cold on the day of 
hatching, and, continuing so, undoubtedly retarded the growth of 
the larva during its first stage. The time occupied between the 
third and fourth moults was much shorter; the third moult was 
during early morning on July Ist, and the fourth moult (and last) 
took place on the 4th, the larva feeding for only two days, as it 
fixed for moulting on the morning of the 3rd, and changed its skin
