528 Notes in 1887 upon lepidopterous larve, dc. 
were present ; upon the 7th abdominal segment the spot 
was only represented by darkened ground colour ; upon 
the 6th abdominal it also possessed a very faint reddish 
tinge, which was rather more distinct upon the spots on 
the other abdominal segments, although the red area 
was always extremely small. There was a faint dark 
cloud on the anal flap, and a dark mark below its 
lateral margin. Each of the four anterior claspers 
possessed a dark semilunar mark. The thoracic legs 
were red, becoming black at the base, and the ridge to 
which each pair of these legs is attached, was also dark. 
The first and the two last spiracles were brown, the 
others very dark brown, producing the effect of black. 
There were two slight smoky patches, the one anterior 
and the other posterior to each of the spiracles; espe- 
cially faint in the case of the prothoracie, and especially 
pronounced in the case of the 1st abdominal spiracle. 
Upon the head the ocellar area was dark and an 
almost imperceptible tinge spread upwards from this 
area over the side of the head. The subdorsal line was 
faint except in its anterior part; the oblique white 
stripes and their borders were also faint, but distinctly 
visible. No traces of an 8th stripe could be made out, 
as in the early stages of Smerinthus and S. ligustri. A 
faint dark tinge was present between the 2nd and 3rd 
thoracic segments at the spiracular level, and this, 
spreading outwards, formed a somewhat distinct patch 
on each side of the larva. This patch was separated 
from the prothoracie spiracle in front, and the Ist 
abdominal spiracle behind, by a distance which corres- 
ponded to that between the abdominal spiracles, and 
thus the existence of an additional spiracular patch, 
making a complete series with equal intervals, was sug- 
gested, as in the case of certain varieties of Smerinthus 
populi. (See Trans. Ent. Soc. Lond., 1885, p. 305). 
The ground colour was yellowish green beneath, light 
bluish green above, the demarcation being sharp, and 
taking place at the subdorsal level, as in many larve of 
Smerinthus ocellatus. A median dorsal line, somewhat 
darker than the adjacent ground colour, was present. 
(2). The second larva was rather bluer beneath: the 
white stripes and their borders of dark ground colour 
were very distinct, as was the whole length of the sub- 
dorsal line. The red spots were very distinct but very
