hairs and stout peg-like spines; abdominal structure not determinable from 

 the single specimen at hand. 



This species has been described mostly from ten specimens 

 mounted on slides. The color and other notes relating to the 

 external appearance of the different stages have been made from 

 living specimens in the field. The material was collected by the 

 writer on Loranthus sp., a parasitic plant related to mistletoe, 

 growing in this case on soursop (Anona muricatd) in the experi- 

 mental orchard of the Department of Science and Agriculture 

 Botanic Gardens, Georgetown, British Guiana, in September, 

 1918. 



The types are in the United States National Collection of 

 Coccidae. 



It may be of some interest to note that only this single colony 

 of the species was observed, although a number of parasitic plants 

 were examined in various parts of the gardens.
