and forcing it back again into the dish. Continue this for about five 

 minutes or until the whole mass is like a thick cream. It may 

 now be readily diluted with cold water. This standard emulsion if 

 covered and kept in a cool place will keep for a long time. For 

 spraying for this insect, in winter, take one part of the standard 

 emulsion to every four parts of water, and spray thorougHily as only 

 the scales which are touched by the spray are killed. 



THE NEW YORK PLUM SCALE. 



Eulecanium cerasifex (Fitch). 



These scales are brown, hemispherical bodies, about one-eighth of 

 an inch in length and with a dark brown, shiny surface, sometimes 

 wrinkled slightly. 



During the early summer these scales are soft but by the middle of 

 June they have become hard and are filled with eggs which have 

 been laid by the female insect under her own body. The number 

 of eggs under each scale has been estimated at between one and 

 two thousand. The young hatch in July and crawl to the under 

 side of the leaves, settle down and begin to suck the juices. They 

 remain here until the last of August when they go back onto the 

 twigs. The treatment for the Apricot scale as given above will 

 answer fully as well as any for this insect also, using one part of 

 the standard emulsion to four parts of water. Spray once in the fall 

 before winter closes in and if possible once or twice in March. 



THE TERRAPIN OR PEACH SCALE. 



Eulecanimn nigrofasciatiun (Perg). 



This scale insect has been found feeding on the peach most exten- 

 sively, but feeds also on the plum, apple, linden, birch, maple, syca- 

 more and olive. It is somewhat smaller than the preceding Leca- 

 niums and the scales are reddish brown, elevated oval or pyriform. 

 The top of the scale is lighter than the sides. They pass the winter 

 nearly full grown and become adult in the spring. Hatching of the 

 eggs begins about June lo and continues for nearly a month. The 

 young settle down on the under side of the leaves and suck the 

 juices until Jthe last of August when they return to the twigs and 

 branches for the winter. 



The fact that these scales are nearly mature before winter sets in,
