they attack; an application of Paris green 
dusted over the plants is very destructive to 
them, but being so dangerous a poison, we 
recommend hand-picking and burning of the 
bugs in preference. The application of 
tobacco-water, whale-oil soap, etc., is use-

a saw-fly, called by Harris Zelandria Rose, 
an insect about the size of a common house-

May and June. The female flies puncture 
the leaves in different places, depositing their
