Eemarks : Senator R G. Churchill, of Berea Park Eoad, Durban, 
wrote to Claude Fuller in November, 1913, regarding this species. He 
says : " My attention has been drawn to an insect blight on many of the 
large shady Umkuhlu-trees in the grounds and avenues in Durban — some 
trees looked as if seriously injured by it. It begins on the main trunk and 
works its way up and outwards to the young top shoots, which eventually 
become white with it." In the specimen I have before me the insects are 
clustered on the stems and flower-buds, the ovisacs forming large, con- 
spicuous masses. Adults with ovisacs, ova and larvae are present 
(October 31, 1914). The larva of a coccinellid is present, but not in 
large numbers. 
Fuller says the trees, when badly infested, are quite conspicuous, and 
that predaceous or parasitic insects must become numerous, for the serious 
infestation of the trees disappears, almost suddenly, about January.

The South African insect which is referred to this species was found 
in Natal by Claude Fuller on croton, citrus, iron weed {Sida rhomhifolia 
Linn.), Convolvulus sp., and guava ; and has recently been found by the 
writer on grass in Pretoria. When adult it is a striking insect owing 
to the dark subdorsal patches and the very long delicate filaments which 
adorn the body (Fig. 4). These filaments are shed and matted into a 
kind of nest, in which the insect sits while spinning the ovisac.
