problem was undei'takenby him, the results of which he embodied 

 in an article of some fifty pages, which appeared in the 'Agri- 

 cultural Journal of the Union of South Africa' for June, 

 July, and August, 1913. In this article over forty pages 

 were taken up with general discussion and the economic 

 aspect of the bagworm, while about nine pages were devoted to 

 the life-history of the insect in question. 



These published accounts of the bagworm, based as they 

 necessarily were on more or less chance and discontinuous 

 observations, do not entirely agree with each other, nor are 

 they fully in accord with our observations dviiing the past 

 seasons. They unavoidably treat the insect almost exclu- 

 sively from the economic point of view, while the scientific 

 •aspect has not received the consideration which it so richly 

 deserves. 



(2) Systematic Position. 



The species belongs to the family of PsychidfB, sub- 

 family Psych in [6, and was described by Heylaerts in the 



"'Ann. Soc. Entomol. Belg.,' vol. xxxiv, p. cxxx (1890) as 

 Eumeta junodi. Janse in his 'Notes on the South 

 African Psychidse' places it in the genus Acantho- 

 psyche, while in Fuller's articles, mentioned above, it is 

 always referred to as Chalioides junodi, but I do not know 



•on which authority. The species has been described from 

 male specimens only; the female has not been described.
