Notes in 1887 upon lepidopterous larve, dc. 601 
patch on the anal flap, and the quadrangular brown patches above 
each brown anal clasper, are distinctly shown, together with 
the arrangement of the bristles and their tubercles. The segment 
of which the posterior part is just indicated, is the 8th abdominal; 
the narrow 9th abdominal is very distinct, and it is seen to be 
clearly marked off from the 10th abdominal segment, which is 
-made up of the parts around the anus, and the anal claspers. The 
bristles possess a very well-marked arrangement upon the dorsal 
part of the 9th abdominal segment. 
Fic. 7, x 5°8. A larva rather more than half through the 2nd 
stage, as seen from the left side. The white shagreen dots have 
now appeared and are distinct ; the white subdorsal line is promi- 
nent, and part of the 7th oblique white stripe can be seen. The 
horn is still curved very slightly forward, although this character is 
not indicated in the figure (see fig. 8). The tip is still bifid, 
and the surface is covered with thorn-like tubercles bearing 
bristles (see fig. 9). 
The head is still rounded and, of a generalised larval shape, as in 
the previous stage. 
The larva represented was one of the seven darker varieties, 
with dark pigment strongly developed on the head, thoracic legs, 
claspers, below the anal flap, and round the spiracles. The horn 
was black in all the larve. 
Fic. 8, x 5°8. A larva at the end of the 2nd stage, in the 
resting-period before ecdysis, drawn from the left side. The head 
is in the condition described in fig. 1. The larva was stretched to 
slightly over the average length. The figure is merely represented 
in outline, and the dark parts indicate the arrangement of the pig- 
ment. 
The subdorsal and 7th oblique stripe are indicated by a line 
along the lower edge in each case. The larva represented was that 
one of the ten lighter larve of stage II., which first developed brown 
spots in the position of the red spots upon Smerinthus larve. The 
spots subsequently extended into faint stripes, and the whole feature 
was far more developed in this than in any other larva of the 2nd 
stage. It is shown at its maximum in the figure. The relation of 
the spots to the borders is quite distinct and unmistakeable. The 
patch of pigment between the 2nd and 8rd thoracic segments, pro- 
bably belongs to the next stage, in which it becomes especially 
prominent. The shagreen dots are only seen in profile. The shade 
along the dorsal edge represents the dorsal line, due to a deeper 
shade of ground colour. 
Fie. 9, x 24°5. The caudal horn of the 2nd stage as seen from 
the front. The horn is still bifid, and terminates in two divergent
