192 EIPEESIA TEEEESTEIS. 



in a quantity of loose, curly, woolly filaments secreted 

 by the parent insect. 



Habitat. On the roots of stephanotis, palms, and 

 adiantum, under cultivation under glass. It was 

 found on the two first-named plants in the London 

 district by Mr. Chas. 0. Waterhouse early in the year 

 1895 ; those on adiantum roots at Dublin in 1901. 



In my original description (1. c.) I stated that the 

 anal lobes of the adult female were small and normal ; 

 haying a longer series before me, I now find that this 

 is not the case, and that the lobes of the old adult are 

 almost as strongly pronounced as those of the young 

 adults ; but, as already stated, this somewhat abnormal 

 character is much more strongly emphasized than it 

 otherwise would be by the deeply-seated anal orifice. 



The habits of the species have already been dealt 

 with in Vol. I, p. 63, of this work.
