600 Notes in 1887 upon lepidopterous larve, ce. 
measurement given in the paper. The deep bluish green colour is 
peculiar, and the size very small for so large a species. 
Fic. 2, x 5:8. The larva of S. convolvuli, as seen from the 
right side, and at the end of the 1st stage. The larva, which was 
stretched to rather more than the average length, was in the 
resting period before ecdysis: it was nearly ready for the change ; 
the head of the 2nd stage has been drawn out of that of the 
1st stage, and is now seen beneath the swollen anterior part of the 
prothorax: the 6 ocelli are distinctly visible beneath the skin of the 
prothorax. The black caudal horn, with its bifid termination, and 
very peculiar, although slight, forward curve, is distinctly shown ; 
but the fine hairs upon it could not be indicated with this degree 
of magnification. The chief bristles springing from tubercular 
bases, are quite distinct. The subdorsal is visible, although it is 
probably a feature of the next stage, seen through the transparent 
skin. 
Fie. 8, x 50. The horn of a similar larva in the Ist stage, as 
seen trom the front. The shape is shown in outline ; the details of 
the structure are throughout similar to those indicated in the 
upper part. The taper from base to tip is seen to be slight. The 
fork at the tip is very marked, the figure representing the larva 
with the deepest notch. The commoner form of termination is 
that shown in the next figure. The two terminal bristles are stout 
and large; their ends slightly clavate. The horn is thickly 
covered with fine short hairs springing from small tubercles. 
‘Fie. 4, x 50. The tip of the horn of a similar larva seen 
from the same aspect. This represents the commoner form of tip, 
with the notch slightly indicated. In other respects the structure 
is identical with that represented in the last figure. 
Fie. 5, x 245, The prothorax and head of a larva, similar 
to that shown in fig. 2, in the resting-period, as seen from above. 
The head of the next stage being drawn back, the ocelli are visible 
upon each side of the anterior part of the prothorax. Posteriorly, 
upon the same segment, the first spiracle is seen, upon each side. 
The figure represents one of the five larve which, in the 1st stage, 
possessed the brown prothoracic dorsal plate, and the brown anal 
patches. The plate is distinctly shown, together with the bristles 
which border it, which are similarly placed in larve without 
the brown plate. This structure evidently represents the plate 
which is so conspicuous in wood-boring and burrowing larve, Tor- 
trices, &e. 
Fic. 6, x 24°5. The parts around the anus in one of the same 
five larve, as seen from above and behind. This larva was also in 
he resting-period before the 1st ecdysis. The triangular brown
