Indian tea districts. The patches of snowy white male puparia, all ranged in 

 definite order, form conspicuous objects on the dark green tea leaves {fig. 8). 



Though occurring rather commonly in Ceylon, I have never seen this insect 

 in injurious numbers. More serious damage has been reported from the Indian 

 tea districts. 



The male scales are very much more numerous than those of the female. A 

 large group of male scales is often accompanied by only a single female, which 

 is probably the parent of the colony. Possibly the female larvae have wandered 

 further afield. 



This species is very closely allied to aspidistrcs. The chief superficial 

 distinctions are the unusually long and narrow puparium of the female, the 

 disposition, and the very prominent ridges of the male scales. The structural 

 differences are not very important, the principal being the relatively larger 

 number of orifices in the upper lateral groups of the circumgenital glands. It 

 should, perhaps, rank merely as a well-marked variety of aspidistra;. 



A form in which the female puparium is white was collected in Nuwara 

 Eliya upon Eurya japonica, a plant allied to tea.
