part of each lobe; the mandibles brown. A broad, velvety 
black band extends throughout the dorsal area, and is inter- 
sected by the pale, greenish yellow indistinct dorsal line; it 
is also edged ou each side with a clear yellow stripe, which is 
again divided into black squares by clear yellow segmental 
divisions; these black squares vary in intensity in different 
specimens, in some only occupying the anterior of the 
segment, the other half being of the ground colour; all have 
a mark of the ground colour, varying in size, on the posterior 
part of the segments. The sides are minutely dotted with 
gray, and there is a very indistinct yellowish line along the 
spiracular region. Ventral surface, legs and claspers green; 
of a darker shade than the ground of the dorsal surface. 
When young the black dorsal band, so conspicuous in the 
adult larva, is absent. Feeds on alder; and shortly before 
spinning up the colour entirely changes, becoming dark 
green with purple tinge, and the segmental divisions purple. 
My larve spun loose cocoons amongst the leaves, &c.; but 
in a state of nature they probably form them amongst 
moss, &c., on the trunks and about the roots of alder.—Geo.

Description of Varieties of the Larva of Notodonta Car- 
melita.—Var. 1.—Ground colour white, with a greenish 
tinge on the back, becoming more perceptible towards the 
anterior segments. Down the centre of the back is a blue 
line, extending to the last segment, distinct on the middle of 
the segments, and becoming fainter, or sometimes entirely 
disappearing in the inter-segmental divisions. On each side 
of this line there are scattered a very few, exceedingly small 
white tubercles, each bearing a hair. On each side of the 
central line is another of a much lighter blue, and beneath 
this the ground colour changes to bluish green, or sometimes 
yellowish green. The spiracles are situated a little below this 
line, and their colour is black, and each is surrounded by a 
whitish line, and again a red line around this, the red being 
more marked round the spiracles situated on the posterior 
segments. Between the spiracles is a yellow line, which is 
continued uninterruptedly over the non-spiracular segments. 
Beneath the spiracles the tubercles are more numerous, and 
in those segments bearing neither legs nor claspers a belt of 
tubercles is continued under the belly. The legs and claspers
