wing is greyish-black, with the basal third or half of the costa deep 
pink. Occasionally nearly the whole of the wing has a pink flush. 
CINABRA HYPERBIUS, Westw., var. 
The Rhodesian variety of this Saturniid is a very handsome moth, 
the upper-side of the hind-wings being bright yellow instead of red, 
with a narrow red hind-marginal band, and a sub-marginal bright lilac, 
mauve or slate-blue band, moderately broad in the male, twice as wide 
in the female. Separated from this by a band of the yellow ground 
colour is a rather narrow dark grey post-median band parallel to the 
outer-margin. | Base and inner-margin covered with pinkish hairs. 
A few female examples have the whole of the fore-wing tinted with 
bluish-grey or slate-blue. 
Wing expanse. < 88 (dwarf)-120 mm.; 9 114-128 mm. 
Average size 110-125 mm. 
C. hyperbius is an abundant moth at Salisbury (and is also found 
at Bulawayo), the larva feeding in considerable numbers on a small 
Protea, on whose succulent leaves it thrives and is very easy to rear. 
It is not infrequently found on Brachystegia randiz, but more difficult 
to rear on this food-plant. The eggs, which are broad and depressed 
at one end and narrow, rather pointed, at the other, are light olive- 
brown and are laid in even rows, from two to seven in a row, some- 
times about the end of October, more often in the first half of 
November, and they hatch out in about three weeks. 
Larva. First instar. Bright yellow above, with a lateral row of 
large black confluent spots. Each segment with six small yellow 
tubercles covered with long black sete. Head black. 
Second instar. Dark ochreous-yellow turning to brick-red three or 
four days after the moult, with inter-segmental black rings. A central 
black longitudinal band from head to last abdominal segment and a 
narrow black lateral band interrupted on each segment. Head black. 
Third instar. Entire body bright salmon-pink without black rings. 
Black dorsal, and lateral interrupted bands as in preceding instar. 
Tubercles bright salmon-red, black at apex, each bearing three or four 
stout black sete. On vertex of head a row of six small black 
setigerous tubercles. Head yellowish-olive. Towards the end of this 
instar the colour of the body becomes grass-green. 
Fourth instar. Head and body grass-green. The two posterior 
thoracic segments have six large orange-red tubercles each bearing a 
es Y
