TEANSFOKMATIONS OF SOME SOUTH-AFEICAN LEPiDOPTEEA. 171 



Bun^ea tyrriiena Westwood. (Plate VI. figs. 30, larva, early stage, enlarged, xf ; 

 31, 2nd stage ; 32, 3rd stage ; 33, full-fed ; 34, pupa.) 

 Buncea tyrriiena Westwood, Proc. Zool. Soc. 1849, p. 51, pi. viii. f. 1. 



Larva. 1st stage. Head black ; body pale ochraceous, with paired conical humps from 

 2nd to 11th somite ; each hump has a tuft of short black bristles on its apex ; a 

 subspiracular row of tubercles bearing tufts of short black bristles, and a tuft of bristles 

 at the anal extremity. Spiracles black, surrounded by a narrow buff-coloured ring, 

 which is again surrounded by a row of semilunular spots ; legs and claspers buff- 

 coloured. 



2nd stage. Head and body green, the apices of the paired humps orange, with tufts 

 of short black bristles as in the first stage ; spiracles red ; a subspiracular yellow line 

 bearing a small tubercle, with a tuft of black bristles on each somite; an oblong silver 

 spot on 5th somite (but this character is often absent) ; legs and claspers green. 



3rd stage. Head and body green, merging into light blue dorsally ; the conical humps 

 have disappeared, the tops of the somites being much lower and each crowned by a 

 small yellow tubercle ; four oblong silver spots (two on each side) on the 2nd, 3rd, 5th, 

 9th, and 10th somites, and two on the 12th somite; a roughish yellow wedge-shaped 

 horn at the anal extremity, with some small red tubercles on it ; abdominal area darker 

 and covered with minute silver spots ; legs pale ferruginous ; claspers green. 



Ath and final stage. Head and body similar in colour to the last stage, being generally 

 pale green above and darker green underneath. In some specimens the light blue of 

 the dorsal area disappears, being replaced by pale yellowish green, in others it remains 

 constant ; the dorsal prominences are much reduced and bear no tubercles on them ; 

 there is usually an oblong silver spot on the 5th somite (but this character is not 

 constant, some specimens having no silver spots at all) ; the minute silver spots on the 

 abdominal area have also disappeared. 



This larva in the last two stages bears a marked resemblance to the larva of 

 Gynanisa maia (Klug). Feeds on Celtis kraussiana (Bern.), Natural Order Urticacese. 



Pupa. Dark red-brown or black, of the usual Saturniid form. The transformation 

 is effected underground. 



A common moth in the Durban district, but I did not meet with it in Maritzburg. 



Henucua smilax Westwood. (Plate VI. fig. 35, larva.) 

 Henucha smilax Westwood, Proc. Zool. Soc. 1849, p. 59. 



Larva. Head red ; body, ground-colour pale ferruginous, covered by numerous 

 irregularly-shaped, dark violet-blue spots, surrounded by narrow pale yellow lines ; 

 each somite bears six longish red tubercles with black apices, bearing a tuft of five or 

 six short, black, stinging hairs or spines, which inflict a painful sting if the larva is 

 handled carelessly ; legs red ; claspers pale ferruginous.
