The Scurfy Scale {Chioiiaspis furfiira Fitch) and Oyster 

 Shell Scale {Lepidosaphes nhni Linn.). 



I wish to mention these scale insects and to exhibit illus- 

 trations of them in order to show the difference between them 

 and the San Jose scale. The scurfy scale is pear-shaped, and 

 light-grey in color. The males are much smaller, narrow 

 and nearly white. The oyster shell scale is long and narrow, 

 and usually of the same color as the bark upon which it is 

 fastened. The San Jose scale is circular in shape. These 

 three species are shown in the illustrations. Both of these

scales (scurfy and oyster shell) are single brooded and live 

 through the winter in the Qgg stage. The scurfy scale eggs 

 hatch between the 20th of May and the tirst of June, while 

 the eggs of the oyster shell scale hatch about June first, or 

 usually about a week later than the eggs of the scurfy scale. 

 The remedy is to spray with kerosene emulsion or soap and 

 water during the first half of June, or while the young are 

 still unprotected by the shells or armor which later cover 

 them. There is very little use in attempting to destroy these 

 insects by spraying at any other time of the year, especially 

 when they are in the egg stage, as it is then very difficult to 

 kill them.
