114 ASPIDIOTUS SPINOSUS. 



Gardens, Kew. Was first recorded in 1889. Subse- 

 quently it has not been met with either at Kew or 

 elsewhere in the British Isles. 



It is a North American species, and was first 

 described by Prof. Comstock from specimens on Red 

 Bay (Persea carolinemis), collected in the United 

 States. 



My description of the scale of the female is from 

 British specimens from the collection of Mr. J. \V. 

 Douglas. All my attempts to obtain British examples 

 of the female have, so far, failed. 



Puparium of the male elongate ; colour like that of 

 the female; exuvia3 black and placed towards tlir 

 anterior margin. Secretional covering as in the female. 



Long, about 1 mm.
