Ladysmitli the infestation was especially heavy during the 

 season of 1915, the orchards in that town suffering severely. 

 An idea of its abundance can be gained from the fact that a 

 certain Mr. Sharp, during the winter cleaning of his orchard, 

 destroyedover 20,000 bags on a plot of three-quarters of an acre. 



In the course of time there is little doubt that this bagworm 

 will become adapted to the black Avattle, and it will then be a 

 far greater plague than the Wattle Bagworm, A. junodi. 



Parasites and Diseases. — Fortunately the Lictor Bag- 

 worm is very heavily parasitised. A lot of sixty-four bags, 

 collected in Pretoria, contained only ten apparently healthy 

 larvas, more than forty having been attacked by dipterous 

 parasites of the family Tachinidas. Furthermore, a species 

 of Pimp la, probably identical with that pai-asitising the 

 Wattle Bagworm, also attacks the Lictor, while two smaller 

 hymenopterous parasites have been reared in abundance 

 from this bagworm. It is also subject to a fungus disease 

 Avhicli at times destroys a great number. 



These natural agencies are at present vei*y effective in 

 keeping the species under control, and seasons of great abun- 

 dance are followed by years when it is hardly noticed. In 

 this respect the Lictor BagW'Orm is now in the same stage as 

 the Wattle Bagworm some ten years ago.

This species was once bred by the Avriter from a number of 

 bags found on a silver wattle (Acacia dealbata) at the 

 Westfalia Estates near Tzaheen, Zoutpansbei-g District, 

 Transvaal. The bags were clustered together for pupation, 

 attached to the sides and under surface of a branch by short 

 stalks. Unfortunately no larvee or pupas were preserved at 

 the time, and, as I have not had an opportunity to collect 

 this species again, the immature stages remain for the present 

 unknown. The specimens w^ere collected in March, 1910; 

 the adults emerged on April 20th.
