Notes in 1887 upon lepidopterous larve, de. 589 
compared, except the single one in Division III., which 
was still in the 3rd stage. 
I. The six lightest and bluest larva of the 8rd stage.— 
Of these larve three were large (about 88 mm. long), 
and three small (about 80 mm.). They are arranged in 
the order of relative darkness, the lightest larva being 
described first. 
(1). The lightest and greenest larva was one of the 
small ones mentioned above ; it was painted Oct. 10th, 
and is represented in Plate XVI., fig. 1, x 2. The 
arrangement of the dark markings and relation to the 
green ground colour is sufficiently indicated in the 
figure. This was the lightest of all the larve in the 4th 
stage, and it is seen to be transitional from the darker 
larvee of the last stage, while it is also connected with 
the darker larve of this stage by a very complete series 
of gradations, the chief of which are indicated in figs. 1, 
2, 3, 4,5, of Plate XVI. The larve were still covered 
with shagreen tubercles as in Smerinthus and Sphinx 
ligustri; these are not shown in the figures. 
(2). All the five remaining larve were dark varieties ; 
the least dark of these was (2), one of the small larve, 
which possessed distinct stripes and borders, together 
with faint traces of the green ground colour, while the 
subdorsal became distinct in its anterior part. This larva 
is represented in Plate XVL., fig. 8, x 2, and it is seen 
to afford a beautiful transition towards the darker larve. 
(3). One of the larger larve possessed a very distinct 
subdorsal line, and a fairly distinct subspiracular, both 
these lines remaining light and contrasting strongly 
with the dark larval surface. The red spots could be 
made out plainly, but they were very dark, almost black. 
(4). Another of the large larve was similar, only the 
two longitudinal lines (subdorsal and subspiracular) 
were not so bright and distinct. 
(5). The third of the larger larve, in which the 
stripes and red spots were so dark that they could 
hardly be distinguished from the general surface of the 
larva. The two longitudinal lines were distinct, and of 
a bright yellow colour, as in Plate XVL., fig. 4, which 
represents one of the larve of Division III. 
(6). The third of the smaller larvee was much like the 
last only still darker, although the stripes were more 
distinct.
