The bag of this pretty little species greatly resembles that of 

 Monda major, but is smaller, more pointed, and differently 

 constructed (PL XIII, fig. 20). It has been reported from 

 Delagoa by the Eev. Junod, in the following terms : 



" Le fourreaii de cette espece est plus petite encore (que M. 

 delicatissima) et se compose de bouts de bois entasses en pyramide 

 autour du sac interieur. L'image est blanc aussi avec une suffusion 

 de noir sur les ailes anterieures." 



In Natal this bagworm appears to be rare, and only twice 

 has a bag of this species been sent to me — the first collected 

 by Mr. Janse, in Stella Bush, Durban, the second by Mr. 

 Piatt, from the same locality. Both were males. The first one 

 disclosed the moth in February; the second was an empty 

 bag from which the male had emerged. 



The life-history, immature stages, female moth, food-plants, 

 and number of generations are unknown. 



The Bag. — The following description is based on an 

 empty bag from Avhich the male had escaped (text-fig. 24, a, b) : 



Length of bag 13 mm., width 6 mm., consisting of two 

 parts — an upper, almost spherical (the bag itself), and a long, 

 slender neck. The rounded part consists of a very thin layer 

 of silk, to which are attached small pieces of leaf, irregular in 

 shape and direction, which are fastened down over practically 

 their entire surface so as to conform to the rounded outline 

 of the bag. The majority of these are attached horizontally 

 or obliquely ; none were found directed verticall3\ On the 

 neck part these covering pieces are lacking; only some minute 

 particles are found interwoven with the silk. 



Inside this case we find a narrow, cylindrical inner bag, 

 extending as a continuation of the neck to the upper end and 

 slightly wider in the middle. This inner bag, which reminds 

 one of that made by A. junodi, extends like a cylindrical
