keels, the majority running the entire length. It is very 
delicately ribbed transversely by about thirty-six ribs. When 
first laid it is of a yellowish pearl-white colour, gradually 
becoming deeper, and when twenty-four hours old it assumes 
a light copper-pink hue, and finally turns to a rosy-orange 
pink. The shell glistens with blue in high light, the orange 
showing in shadow. The rosy colouring is retained until a 
day before hatching, wiien it then changes to a leaden-grey. 
The eggs hatch in six or seven days. 
Larva. Upon emerging, the little larva devours the greater 
part of the egg-shell as its first meal. During its first stage, 
lasting eight days, the larva feeds on the cuticle of the upper 
surface of the leaf. After its first moult, it perforates the leaves 
when feeding. 
After the fourth moult and fully grown, when thirty days 
old, the larva measures 33*40 mm. in length, and is almost 
cylindrical in shape, being only slightly attenuated at each 
end. It is entirely of a green colour, exactly similar in tint 
to that of the upper surface of a Clover leaf. The entire sur¬ 
face, including the head, legs and claspers, is densely sprinkled 
with extremely small black warts, each emitting a very fine, 
short white hair, giving the whole surface a somewUat velvety 
appearance. The side is adorned by a very beautiful and 
conspicuous spiracular stripe, composed of yellow and bright 
orange-vermilion streaks alternating, the yellow on the 
anterior half and the red on the posterior half of each segment. 
The spiracles are white. The upper edge of the stripe is out¬ 
lined with white,'and directly below the red mark is an 
intensely black spot on each segment, from the third to tenth 
inclusive. This particular larva described was thirty-one days 
in its larval state. 
Pupa. The pupa measures 22 mm. long. The head ter¬ 
minates in a slightly-upturned point; the thorax is swollen 
and somewhat rounded and very slightly keeled ; the wing 
is dilated along the inner margin and considerably swollen 
about the middle of the costal area. The colour of the head 
is dark olive-green above, sharply defined laterally by light 
greenish-yellow, and clear green underneath. The whole 
of the dorsal surface is a light green with a darker green line 
running down the back. There are from three to four small
