This coccid has been received frequently for identification, espe- 
cially from plant-quarantine inspection sources, and in consequence 
several hundred specimens have been examined in the course of this 
study. Material has been studied from every political unit border- 
ing the Mediterranean except Albania and Turkey, from Portugal 
in “Europe: from Russian Caucasus, Russian and Chinese Turkestan, 
Persia (Iran), Kashmir and elsewhere in India in Asia; from 
Argentina in South America; and from Arizona, California, and 
Maryland in the United States. From the fact that some of these 
specimens are from noncultivated species of Pyrus and Ligustrum 
growing in wild and mountainous areas in Turkestan and Caucasus, 
it may be legitimate to assume that this area represents the original 
home of this insect, and that it has spread gradually through the 
remainder of its present known area of distribution as a result of 
dissemination of infested plant material. The frequency with which 
the species has been found at quarantine on various commercially 
produced rosaceous fruits, together with the experience already re- 
ported for Arizona (45) and Maryland (42), indicates that in this 
insect there has been definitely established in the United States 
another potential fruit pest.
