ber of cases it has caused serious damage. It occurs on peach, plum, 

 apple, pear, Bohinia pseudacacim^ and "Climbing Jasmine." 



Whale-oil soap at the rate of 1 pound to 1 gallon of Avater, and 20 

 per cent kerosene, as winter washes are the remedies generally used. 

 (3) Aspidiotus ancylus Putn. 



Quite generally distributed over the State on apple, oak, osage 

 orange, Gleditschia triaccmtJws^ U/ in >/.•>■ a //tericana, and Populus frem- 

 uloides, but never occurs in perceptibly injurious numbers, 

 (■i) Asjyid lotus osborni Newell & Ckll. 



Taken on Quercus aquatica at Atlanta, Fort Valley. Marshallville, 

 Tifton, and Poulan, Ga. 



According to Mr. Marlatt (in litt.) the distinctness of this species 

 from A. ancylus is doubtful. 



(5) AspidloUtsjuglans-regke Comst. 



Occurs very abundantly in extreme south Georgia, hut rarely in 

 middle Georgia, on peach, plum, and prickly ash. In a few instances 

 it has been seriousl}^ injurious, necessitating treatment. 



(6) Aspidiotus hederce Vail. 



This species occurs in south Georgia, badly infesting China trees and 

 oleander, and is a common pest in most of the greenhouses of the 

 State; on palms, Cycas revoluta, Jasminiuiii <jrandiJlora, and orange. 

 The treatment generally adopted ])y florists is lemon-oil wash. 



(7) Aspidiotus Ji ens Ashm. 



This is a bad pest in most of the greenhouses in the State, on palms, 

 Cycas revohita, and ferns. The writer has made extensive experi- 

 ments at Augusta and Marshallville on the use of hydrocyanic-acid gas 

 as a remedy for greenhouse pests, with the result that A. ficus and 

 other greenhouse insects were destroyed by the gas. No injury 

 resulted to the common run of greenhouse plants where the remedy 

 was properl}" applied. 



(8) Aspidiotus cydonice Comstock. 



Found in a greenhouse at Savannah on Cycas revoluta. 



(9) Aspidiotus uvce Comst. 



This species is common in Atlanta on the sycamores used for shade 

 trees. According to Mr. Marlatt, who identified the specimens, it has 

 not hitherto been known to occur on this food plant. 



(10) Asjyidiot'us tenehrlcosus Comst. 



As a rule the maple shade trees all over the State are infested with 

 this scale insect. The damage to these shade trees in the cities is great, 

 finally causing their death. 



(11) Aspidiotus ohscurus Comst. 



This is a very abundant species widely distributed over the State on 

 oaks. It is quite injurious to the oak shade trees in the cities and also
