TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA. 305 
- folding over a blue transverse streak at the incisions of the somites. Head and 
thoracic legs ferruginous, spiracles white, with ferruginous centre. 
Tn the early moults this larva is ferruginons, the head and thoracic legs being black. 
Feeds on Sclerocarya caffra (Sond.), called in Natal “the wild mango tree”—a 
common tree in the coast districts, but not found higher up. 
When about to change the larva spins a greyish-white silky cocoon, with a line of 
ventilation-holes round the exit end, which it attaches longitudinally to a twig of the 
food-plant. The pupa is chocolate-brown and of the usual shape. This moth appears 
to be double-brooded, the larva appearing in November and February, and the perfect 
insects in January and the following October. 
Common at Sydenham, near Durban. 
2. NUDAURELIA WAHLBERGI (Boisduval). (Plate XLVII. fig. 4, larva; fig. 5, pupa.) 
Larva. Ground-colour deep velvety black, each somite bearing four branched 
ferruginous spines with reddish bases, two subdorsally and two laterally, from 2nd to 
12th somite inclusive, the spines on the 2nd somite having black bases. Between the 
subdorsal and the lateral row of spines are placed a collection of small yellow spots on 
each somite; the red bases of the subdorsal and lateral spines being joined on 10th 
and 11th somites. Spiracles white: a subspiracular row of small yellowish tubercles 
bearing a few whitish hairs, one on each somite. Head and legs concolorous with 
body. 
Feeds on English oak, but has also been taken in large numbers on peach-trees, in 
gardens in Maritzburg—both these trees being imported species in Natal. When full- 
fed it burrows underground, where it makes a sort of web !, inside. which it undergoes 
its transformation. Individuals which changed about 14th March reappeared as 
imagines on 6th May and subsequent days. 
Pupa dark chocolate-brown. 
Common in Maritzburg. 
3. BuNnmA CAFFRARIA (Stoll). (Plate XLVII. fig. 8, larva.) 
Larva. Ground-colour deep velvety black ; each somite, from 4th to 12th, bearing 
eight yellow tubercular processes, two subdorsally, two laterally, and four (in two rows) 
on each side subspiracularly. The 2nd somite bears four black processes, two sub- 
dorsally and two laterally; the 3rd somite bears four black processes, as in the 2nd, 
‘ «The group of Antherwa to which this species belongs—Nudaurelia—is noted for forming no cocoon, 
and the closely allied species A. (IV.) cytherea, menippe, and tyrrhea, as well as Bunea caffraria, as far as I 
have observed, simply bury themselves without any attempt at forming even a ‘ web.’”—R, Trrmen.
