Notes in 1887 upon lepidopterous larve, dc. 529 
small, especially on the 7th abdominal segment. The 
anal flap was without the dark cloud, and+he dark mark 
below it and on each of the four anterior claspers, was 
very faint. The thoracic legs were paler than in the 
last individual. Upon the head there was only a faint 
cloud on the ocellar area. The latera] mark between 
the 2nd and 8rd thoracic segments was present; the 
patches on each side of the spiracles were fainter and 
very slight, and they were entirely absent in the case of 
the 1st spiracle. On the other hand the 6th abdominal 
spiracle was dark-brown, almost black. 
(3). The appearance of the 3rd larva is represented in - 
Plate XV., fig. 10, x 8. There was a slight dark cloud 
upon the border to each oblique white stripe ; it appears 
upon the border just as it enters the posterior of the 
two segments in which its course lies, and just above 
the level of the subdorsal line. The stripes and borders 
were less distinct than in the larva last described, but 
they are represented more distinctly in the figure, so that 
in this respect the appearance of the 2nd larva is given, 
rather than that of the 38rd. The red spots were much 
larger than in the two larve described above. The last 
spot was much fainter than the others. The head was 
bright yellowish green, as in the other bluish larve ; and 
as in the young bluish or whitish larve of Smerinthus 
ocellatus. The dim lateral shade was developed to the 
extent shown in the figure. The spiracles were like 
those of the 2nd larva, but the patches were more 
distinct. The distinction between patch and spiracle 
could not be indicated on a drawing of the size of the 
figure. The smoky patch was very faint in the case of 
the prothoracic spiracle, but it tended to pass backwards, 
so as to nearly fuse with the patch between the 2nd and 
8rd thoracic segments. The median dorsal line was pre- 
sent, as in all these larve. The ground colour was not 
quite such a whitish blue-green as in the last individual. 
The extremely Smerinthine appearance of these three 
larvee is well shown in fig. 10. 
(4). The fourth larva was less decidedly bluish green, 
and tended somewhat towards an intermediate variety. 
The horn was very black, and the transparent zone was 
only slightly marked. The red spots were rather larger 
than in the larva last described, but they were otherwise 
similar. There was only a slight dark shade upon the
