It has been found by the authors at the following localities 

 in New Jersey: Arlington, Rutherford, Far Hills, Riverton, 

 Palmyra, Springfield, Nutley and New Brunswick, and is also 

 known to occur at Bala, Pennsylvania ; Washington, D. C. ; 

 Holland and Japan. It was evidently introduced into New 

 Jersey in the egg stage on evergreen azaleas from Japan, as 

 quite a few Japanese azaleas have been imported into New 

 Jersey during the past few years. We have found it infesting 

 the following species and varieties of azaleas : Hinodegeri, 

 Amoena, Ledifolia alba, Benigeri, Yodogawa, Kaempheri, 

 Pontica, Mollis, Indica, Shirogeri, Hatsugeri, Shibori, Amura- 

 saki, Schilippenbachii, etc., the deciduous varieties, however, 

 not being as badly infested as the evergreen ones. 



The injury is caused by the nymphs and adults feeding on 

 the under surfaces of the leaves, abstracting the sap and re- 

 sulting in a discoloration of the foliage on the upper surface. 

 In severe infestations, the leaves become almost white, many 

 of them drying completely and dropping off, and the under- 

 sides of the leaves are also disfigured by the excrement of the 

 insects. 



The winter is passed in the egg stage and hatching takes 

 place about the latter part of May in central and southern New 

 Jersey. The length of each nymphal stage varies from three 

 to six days, depending on the temperature. About the latter 

 part of June adults appear and egg-laying takes place, this 

 operation extending over an average period of two weeks. 

 These eggs require on an average two weeks for hatching and 

 by the last week in July and first week of August growth is 

 completed and many new adults are present. During the first 

 two weeks of August eggs are again laid and by the middle 

 and last week in September many adults of this brood are 

 present, the over-wintering eggs being deposited at this time 

 and during the first part of October. Adults, mostly females, 

 have been noted lingering on the plants as late as the middle 

 of November. Thus there are three broods in southern New 

 Jersey, the average length of each being about one month. In 

 the central and northern parts of the State there are only two, 

 and a partial third. On account of the extended oviposition
