304 L1EUT.-COL. J. M. FAWCETT ON THE 



and two small yellow processes on each side, in line with the subspiracular processes 

 on the other somites. Spiracles red; those on the 4th to 11th somites being sur- 

 rounded by an irregularly shaped red area. Head and legs concolorous with body. 



Larva figured has not attained its full size. 



Mr. Quekett writes : " The food-plants of this Buncea are, at Durban, Celtis kraus- 

 siana (Bernh.), and Ekebergia meyeri (Presl), and at and near Maritzburg a species of 

 Cussoma, on which I have taken the larva? in the Botanic Gardens." 



This larva, which much resembles that of N. wahlhergi, undergoes its transforma- 

 tion underground in a similar manner to that larva, and is double-brooded, the larvae 

 appearing in November and December, and the second brood in March and April ; 

 these latter individuals remain pupa? until the following October, my first specimen 

 emerging on 12th of that month. 



Piipa dark reddish brown; very similar to that of Gynanisa maia (Klug). 



4. Gynanisa maia (Klug). (Plate XLVII. fig. 6, larva ; fig. 7, pupa.) 



Larva. Ground-colour pale green, with paired dorsal series of humps ; each somite, 

 from 2nd to 12th, bearing four silver spikes with yellow points inclined backwards, one 

 subdorsally 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, with a black edge, which 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 lower edge a yellow raised lateral line bearing a small orange-coloured 

 tubercle on each somite, and thickening 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 with minute white spots, and a row 

 of small red tubercles, one on each somite just above the claspers, which are green. 

 Thoracic legs pale brown banded with black. 



Feeds on the common wattle (Elephantorrhiza burchellii, Bth.) and on several species 

 of thorny acacia. "When full-fed the larva biu*rows underground, and there undergoes 

 its transformation, making little or no preparation in the way of a web. 



The pupa is dark reddish brown, and is remarkable for the large size of the antenna? 

 covers. The moth is double-brooded, the larva? appearing in November, and the 

 imagines emerging end of January ; the second brood of larva? appearing in March and 

 emerging in the following October. At Fort Napier, Maritzburg, the wattle-trees were 

 completely cleared of their leaves by the March brood this year. 



If the collector possesses one female, any number of males can be secured by placing 

 the female in a box on the verandah. The writer has seen as many as twenty males at 

 one time fluttering round the box about 10 p.m. Next morning the verandah was 

 strewn with their wings, a cat, as was subsequently discovered, having caught and 

 devoured them.
