TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA. 299 



median dorsal pink stripe from head to tail, bounded by an olive-green stripe on each 

 side. 1st segment reddish brown superiorly, with short tubercles on each side ; a pair 

 of short pink tubercles dor so -laterally, bounded inwardly by dark olive-green, and 

 joined by a fine pink transverse line on 2nd and 3rd segments; tail bifid. 



2nd stage. -Pale green above, darker green underneath ; all the markings described 

 in 1st stage defined by slightly darker green, except the olive-green area on the back 

 of the thoracic segments, which has become dark green in this stage, while the pink 

 median dorsal line and transverse stripes have become a rather startling whitish cross. 



ord (and final) stage. Shortly before changing into a pupa the larva loses all its 

 distinctive marks, and becomes very pale yellow all over, almost diaphanous. 



Feeds on Popovia caffra (Kaffir name, " small Maswinda "), a common shrub in the 

 coast district. 



Pupa. Bright green. On each side of back, from apex of dorso-thoracic projection 

 to anal extremity, a narrow yellow elevated stripe ; on summit of back a pair of similar 

 stripes commencing considerably apart near base of dorso-thoracic projection, and 

 converging till they meet at anal extremity. A series of diamond-shaped lozenges 

 down the back, medially, and a series of diagonal streaks subdorsally between the two 

 yellow stripes, and extending beyond them to the cephalic area. Duration of pupal 

 stage 21 days (24th January to 16th February). 



Common in Durban and the coast-zone. I have taken the allied species Papilio 

 leonidas in the same coverts and at the same time. It is, I should say, doubtful if 

 they are distinct species. P. brasidas is the commoner species in the Durban district. 

 1 have not met with either in the vicinity of Maritzburg. 



16. Papilio moeania (Angas). (Plate XLVI. figs. 37-39, larva; fig. 40, pupa.) 



Larva (early stage). General colour grass-green on back, incisions of segments pale 

 blue ; two dark chocolate-brown lateral stripes above spiracles (which are white). 

 Head, thoracic legs, claspers, and bifid tail brownish yellow. 1st segment yellow 

 dorsally, bearing two short tubercles on each side ; 2nd and 3rd segments bearing 

 dorso-late rally a pair of black spines, short, with orange bases, and joined by two broad 

 transverse streaks of chocolate-brown ; that on the 2nd segment having three brown 

 spots posteriorly, and that on 3rd segment five brown spots anteriorly, and being much 

 larger than the other, extending posteriorly over part of the next segment ; from this 

 three dark brown longitudinal lines, one dorsal and two subdorsal, extend to the 

 11th segment, where the two subdorsal lines become two chocolate-brown spots joined 

 by fine transverse lines, while the dorsal line (which is much finer than the others) 

 extends to the tail. A double lateral line of black spots along the segments, two on 

 each segment along the upper line, and one on each segment in the lower line. 



2nd stage. On casting its last skin, the larva emerges exactly the same as in the
