Notes in 1887 upon lepidopterous larve, dc. 541 
noted that the dark spiracular band on the thoracic 
segments was wider and that the horn was blacker. The 
oblique stripes were white. 
(2). A dark variety about equal to (4) of the previous 
lot. An exact comparison was very difficult, especially 
because of the change of colour during growth, and also 
- because the darkness varied in different parts of the 
larve, so that extreme darkness in one part might 
be compensated by unusual lightness in another. Thus 
this larva retained the traces of the green ground colour 
as in (2) of Division I. (fig. 3). Nevertheless the differ- 
ences between the dark larve were insignificant compared 
to the differences between them and the green larva. 
There was no trace of the transparent zone on the horn. 
(3). A dark variety about equal to (5) of the previous 
division. The ground colour was dark, but the two longi- 
tudinal stripes were very distinct, and the transparent 
yellow zone on the horn very conspicuous; but there was 
hardly any reddish brown colour at the side of the base. 
(4). This larva was darker than any of the previous 
division. The transparent zone on the horn was 
slightly marked. The larva is represented in Plate 
XVL., fig. 5. 
There were faint traces of a bifid termination to all 
the horns except that of (1) which was somewhat dis- 
torted. 
Ill. The six darkest larve of the 8rd stage.—Five of 
these larve were compared Oct. 8th, the 6th being still 
in the previous stage. The lengths of the larve are 
given below. 
(1). The lightest larva was an extremely interesting 
green variety, transitional from the 1st of the last 
division towards the dark varieties. It is represented in 
Plate XVI., fig. 2 x 2. Although much darker than 
either of the other two green varieties, there was never- 
theless a large amount of green colour spreading from 
the stripes. The reddish brown patch at the base of the 
horn was very distinct in this and the other four larve of 
this division. This larva was about 27 mm. in length. 
(2). This larva was about equal to the 5th of Division 
IT. Length 36 mm. 
(8) and (4). These larve were very dark, but the two 
longitudinal stripes were very distinct and of a bright 
yellow colour. The larve would be classified with (6) in
