TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA. 315 



Larva. Ground-colour velvety black, with very long pale yellow hairs ; each somite 

 with two red and four greyish tubercles, from which spring the long silky yellow 

 hairs, except the 4th, 5th, 6th, and 7th somites, on which the two dorsal tubercles 

 coalesce, and from these spring four thick dorsal tufts of shorter grey hairs, and 

 11th somite, which bears a tuft of shorter blackish hairs. Head red above, black 

 beneath ; thoracic legs and claspers red, and a red transverse band on 12th somite. 



Feeds on common wattle (Elephantorrhiza burchelli). 



The pupa is formed in a slight web constructed from the hairs of the larva, and 

 is pale fulvous with black markings ; wing-covers greyish, with veins delineated by 

 thin black lines. The descriptions are made from two specimens reared in Maritzburg 

 in February and March. There is a female specimen of the imago in the British 

 Museum unnamed. 



Family HYPSID^l. 



21. Hypsa aphidas (Hopffer) = #. suhretracta (Walker). (Plate XLVII. fig. 16, 

 larva.) 



Larva. Chocolate-brown ; under surface greyish ; an indistinct dark dorsal line. 

 Three red tubercles, one dorsally and two subdorsally, on 1st to 3rd somites ; paired 

 red subdorsal tubercles, four on each somite, on a black subdorsal line, from 4th to 12th 

 somite ; a broad white spiracular streak on 5th, 6th, 10th, and 11th somites. Head dark 

 brown ; thoracic legs and claspers fuscous. A few sparse brown hairs on the body. 



Feeds on the common fig, both cultivated and wild ; the specimen figured fed on the 

 cultivated fig, but I have reared others which I found as pupse in hollows on the 

 trunks of the wild fig-trees round the gardens in the square at Durban. When about 

 to change, the larva rolls up a fig-leaf in which it spins a web, and the same process 

 is gone through in the hollows of fig-tree trunks. The specimen figured remained as 

 a pupa from 18th February to 22nd March. 



Pupa black, with polished surface. 



Imago fairly common in Durban and Maritzburg. 



Family ARCTIID^. 



22. Spilosoma puella (Druce). (Plate XLIX. fig. 15, larva.) 



Larva. Ground-colour dark fuscous, each somite with six large and two small black 

 tubercles surmounted by tufts of black hairs. A pale ferruginous dorsal line, darker 

 on the summit of each somite ; under surface paler ; head and thoracic legs black, 

 spiracles ferruginous. 



Feeds on the Grenadilla passion-flower,
