 recorded from the Transvaal.

 Larva. — Gynanisa maia, Fawcett, Trans. Zool. See. Lend. vol. xv. p. 804, pi. xlvii. fig. 6. 



Col. Fawcett has thus described the larva : — " Ground colour pale green, with paired dorsal series of 

 humps ; each somite, from 2nd to 12th, hearinfi four silver spikes with i/ellow points inclined hackivards, one 

 subdorsalli) and one laterally on each side; also a number of small silver spots placed irregularly over each 

 somite ; the first somite has no spikes, but is raised to a sharp ridge, ivith a black edge, ichich may be of 

 assistance to the larva in forcing its way through the ground. Spiracles purple, and immediately beneath them 

 a purple lateral line having on its loiver edge a yellow raised lateral line bearing a small oranqe-coloured 

 tubercle on each somite, and thickened considerably above anal claspers, where it has a series of small black 

 tubercles superiorly. Head green, with black side-streaks defining the eye. Under surface darker green ivith 

 minute white spots, and a row of small red tubercles, one on each somite just above the claspers, which are 

 green. Thoracic legs pale hrown banded with black." 



Hab. — Transvaal; Pretoria (Distant), Barberton (Eendall), Lydenburg District (Pret. Mus. and 

 Coll. Dist.). — Widely distributed throughout South and East Africa; recorded from British Central 

 Africa by Butler; and found by Donaldson Smith in his expedition from Somaliland to Lake Lamu 

 (vide Holland). 



The food-plants of the larva have been recorded as follows : — Johannesburg, mimosa 

 (A. Ross, in litt.) ; in Natal, Ekphantorrhiza burchelli, the common wattle (Fawcett) ; in 

 Transkei, mimosa (Barrett *). 



Double-brooded in Natal, the larvae appearing in November, and the imagines emerging 

 end of January ; the second brood of larvae appearing in March and emerging in the following 

 October (Fawcett).

About three species are at present included in this genus, all of which are Ethiopian, 

 and two found in the Transvaal.
