142 FIDONIA BRUNNEATA. 
where the lines of the reticulation meet there is a 
little raised bright white knob (a peculiarity I have 
not yet observed in any other egg), the whole ege 
looking as if set with tiny pearls on a ground colour 
of shining salmon-pink. 
About the end of February, 1868, the eggs grew 
darker, and between March 2nd and 8th four larvee 
emerged, the fifth dying unhatched. After a little 
hesitation they began to eat buds of whortleberry 
(Vaccinium myrtillus), but somehow, within a few 
days, two of them died. ‘The two survivors, however, 
erew on steadily, and from being dark brown at their 
first appearance, after a moult or two began to assume 
a striped dress; the ground colour was now pale 
erey—almost white; the dorsal and supra-spiracular 
lines almost black, with an intermediate subdorsal line 
of brown; and the spiracular stripe tinged with 
ellow. | 
About the 24th of April the larger of the two larvee 
seemed full-grown. At that time it was rather over 
half an inch in length, of uniform bulk, cylindrical, 
the head horny, the skin smooth, but puckered along 
the spiracles. The colouring was disposed in a 
multiplicity of fine lines, which I now give in due 
order. | 
The dorsal line, widening in the middle of each seg- 
ment, dark green, closely edged with almost black 
threads; then a thin white line; then the subdorsal 
line of pale pinkish-brown outlined with darker 
brown; then another thin white line; then three 
olive-brown lines (the middle one palest, and the 
lower one darkest), partly showing distinct, and partly 
run together, so as to form a stripe just above the 
spiracles. 
The spiracular line broad, white, but tinged with 
yellow in the centre of each seoment. ‘The belly of a 
dirty white, with some oblique dashes, and lines of 
brown. 
This larva went to earth at the end of April, and
