The Tobacco Flea-beetle (Epitrix parvula Fab.) 
A small, dark, active beetle, provided with strong hind legs that 
enable it to jump readily, injures the leaves of tobacco both in the seed 
bed and in the field by eating numerous small holes in them. If one 
of the beetles be examined closely, it will be found to have a darker 
band across its back, and its wing covers are finely pitted. 
The adults appear from their winter hiding places early in the spring. 
Eggs are laid on the ground or on the plants. The larve live in the 
eround, feeding on small roots. 
Seed beds that are closely covered with cloth will not be injured. 
The adult beetles may be killed by thorough spraying with arsenate 
of lead or Paris green. 
The Spinach Flea-beetle (Disonycha xanthomelena Dalm.) 
A much larger species of flea-beetle commonly attacks spinach, 
and is often a serious pest of sugar beets. The adult is one fourth 
of an inch long, with yellow thorax and shining blue wing covers.
