is decidedly imitative of atropos-moth, so much so that I have taken it for atropos 
when at rest on a tree-trunk. At Cape Town both the dark forms (of solani and 
atropos larve) are rare in comparison with the green ones.” 
Subfamily MacROGLOSSIN&. 
16, CerHonopes uywas (Linneus). (Plate XLVIII. figs. 13-18, larva; fig. 19, pupa.) 
This well-known insect has been reared from six different forms of larva in Natal, 
which show almost every gradation from an almost wholly green larva with white 
subdorsal stripes to an almost wholly black one, in which the subdorsal stripes are 
replaced by very dark grey ones. 
The various forms will now be described in detail. 
Larva. 1st form. Ground-colour pale green, a white-bordered light blue dorsal line, 
and a thin white subdorsal line bordered superiorly by a thin carmine line, the combined 
lines ending in a yellow streak at the base of the horn. Spiracles white, bordered 
with red edges, that on 11th somite surrounded by a rufous area. Head green, 1st 
somite beset with yellow tubercles superiorly ; thoracic legs and claspers brownish ; horn 
green, curved and pointed, and beset with yellow tubercles. Plate XLVIII. fig. 13. 
This seems to be the Indian form described by Hampson in ‘ Fauna of British India.’ 
2nd form. Ground-colour pale green; a white-bordered blue dorsal line ; a subdorsal 
white line defined in places superiorly and inferiorly by small black oval spots ; under 
surface, legs, and claspers pale brown. Spiracles white, surrounded by oval red areas ; 
a yellow subspiracular line, interrupted and defined inferiorly with black, which curves 
up vertically on the posterior half of each somite from 6th to Yth, otherwise as in 
Ist form. Plate XLVIII. fig. 14. 
3rd form. Similar to 2nd form, but differing in the following characters :—The dorsal 
line is dark grey ; the black oval spots defining the white subdorsal line inferiorly are 
much more numerous and extend downwards between the spiracles till they meet a 
black subspiracular line. The red areas surrounding the spiracles more enlarged. 
Plate XLVIIL. fig. 15. 
4th form. Similar to 3rd form, but differing as follows :—Dorsal line darker, the 
black oval spots defining the white subdorsal line inferiorly are coalesced into a con- 
tinuous black lateral line ; and the whole body below it is pale brown, with only an 
isolated patch of green on each somite round the red spiracular areas. 1st somite 
yellow, covered with small yellow tubercles. Plate XLVIII. fig. 16. 
Sth form. Dorsal and subdorsal stripes as in 4th form. Ground-colour black ; 
a rufous area round each spiracle, and a few irregular yellow marks on each somite ; 
a few traces of the yellow subspiracular line, and a yellow patch at base of horn; 
claspers and anal extremity brown; head and Ist somite yellowish. Plate XLVIII.
