Notes in 1887 upon lepidopterous larve, dc. 547 
The other larva was light, and (at this time) interme- 
diate between the two lightest larve of Division I. 
Its appearance is represented in fig. 6 (natural size). Both 
these larve were kindly preserved by Lord Walsingham, 
and are now placed in the Natural History Museum, so 
so that they will be always available for comparison. 
Division LIT. of the earlier stages (omitting two larve, 
one having died in the 4th stage, while the green 
variety was put in spirits shortly after ecdysis: it is 
quite clear that the latter larva would have been dark). 
All four larve were dark varieties; three being very dark 
indeed, with small spots representing the subdorsal line, 
and hardly any trace of the oblique stripes. In one case 
these spots were almost absent, and there was no trace of 
the stripes. The fourth larva was remarkable, in that the 
subdorsal line and stripes were distinct, the former for its 
whole length, although the larva was a dark variety. 
This latter larva is represented in fig. 8 (natural size). 
All the fourteen larvee were arranged in the order 
of relative darkness as follows :—

The asterisks are affixed to the larve which were 
figured ; they are shown in figs. 6—10 on Plate XVI. 
The larve marked ° possessed a light-coloured and 
extremely prominent subspiracular line; in the others 
this line varied from a light brown colour, almost like 
the marked larve, up to a distinct brown tint; but 
this feature was always extremely distinct, and formed 
by far the most prominent marking of the larve. The 
horn is now curved and shining, like that of Sphinx 
ligustri_in the last stage. The prothoracic dorsal plate 
is very distinct and polished (see figures).
