TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTEKA. 313 



dith form. Entirely black, with the exception of the red areas surrounding the 

 spiracles, and the head, base of horn, and anal extremity and claspers, which are dull 

 ferruginous ; dorsal line black ; subdorsal line and 1st somite dark grey. Plate 

 XLVIII. fig. 18. 



All these forms of larva were found at the same time feeding on Gardenia and also 

 on Kraussia lanceolata (Sond.). When ready for their transformations the larvae 

 burrowed underground, and there underwent their change to pupae ; the perfect insects 

 emerged in from 3 to 4 weeks. In order to test whether all the different forms of 

 larva produced the same imago, each form of larva was placed in a separate box 

 and carefully labelled, but when the imagines emerged it was impossible to detect any 

 difference between them. 



Pupa. Dark reddish brown. 



The imago seems common all over Natal. 



Family ZYGiENID^E. 



17. Ztg^ena (Anteris) ampla (Walker). (Plate XLIX. figs. 27, 28, larva; fig. 29, 

 cocoon.) 



Larva. Ground-colour white, with pink stripes and black spots. A white dorsal 

 line bordered by two subdorsal rows of black spots, two on each somite ; beneath these 

 a pink lateral line bordered inferiorly by a white spiracular line, on which is situated 

 a row of smaller black spots in groups of two on each somite. A subspiracular pale 

 fulvous line, and below it an interrupted line of black lunules, one on each somite ; 

 under surface and claspers white ; head black, with a white bifid frontal stripe. 



General form of larva thick in middle, tapering towards extremities, and very similar 

 to larva? of Lycsenidse in shape. 



Feeds on a bush with very large leaves with spiny edges (like holly) of which I 

 have not been able to obtain the name. 



The pupa is formed in a strongly-woven oval cocoon, usually pale fulvous, and 

 affixed to a leaf of the food-plant ; time passed in pupal stage about 25 days (March 

 3rd or 4th to March 29th, 1899). 



Found in large numbers on the food-plant in the Back Beach Bush, Durban. 



Family LASIOCAMPIDJE. 



18. Gonometa postica (Walker). (Plate XLIX. figs. 3, 4, larva; fig. 5, cocoon.) 

 Larva. There are two common forms of this larva in Natal, one with long grey 



hair and one with long fulvous hair. 



1st form. Ground-colour deep velvety black, thickly covered on sides with long grey 

 hair ; a thin black dorsal line and paired black subdorsal patches of short black hairs 

 on each somite from 4th to 12th. Head black, covered with brownish-grey hairs ;
