Notes in 1887 upon lepidopterous larve, éc. 525 
many Smerinthus larve is obvious, and hence the fact 
that the brown borders are certainly connected with the 
spots, becomes of great importance. There will be far 
more evidence of this in the next stage. The faintest 
trace of brown spots could now be seen upon another 
larva of the same division, but they were so slight that 
their presence would not have been noticed except for 
the clue afforded by the former larva. The seventh spot 
was only represented by a darkening of the green ground 
colour. The seven dark larve were also carefully 
examined, and traces of one or two brown spots were 
perhaps present upon two of them, but I could not feel 
sure of this. The upper part of the seventh stripe was 
present, probably upon all of them. 
On Sept. 23rd the seven dark larve were again 
minutely examined, and it was noticed that the upward- 
extending part of the subdorsal line,—in mature larve 
which had not yet entered the resting-stage before 
ecdysis,—was distinctly divided into oblique white 
stripes, of which each pair tended to meet and form a 
V, with the backward-directed apex interrupted by the 
dorsal line, due to the underlying dorsal vessel. In 
some larve five distinct, oblique, white stripes could also 
be made out below the subdorsal, and two more very 
faint ones in the most strongly marked individuals. The 
continuity between the upper and lower sections of an 
oblique line, above and below the subdorsal, was obvious 
in two or three of the segments. 
Very slight traces of brown spots,—often a mere dark- 
ening of the ground colour, with sometimes the faintest 
brownish tinge,—could now be made out on most of these 
larve. Hach spot was always placed just below the 
lower edge of the subdorsal, in such a position as to 
form the upper part of a dark border to the oblique 
white stripe, whether the stripe itself was present or not. 
The ten light larve were also examined at the same 
time. The brown-spotted larva was now in the resting- 
period. The dark pigment upon it had not undergone 
any further change since the last description of the 
larva on Sept. 22nd. There were now distinct traces of 
brown borders extending from the three posterior. spots, 
and very slight traces extending from the four others. 
No stripes could be seen except the upper part of the 
last, which was distinct. This larva in which the spots
