The turnip aphid ( Hhopalp siphum - cse u dobrassicae Davis) was unusu- 
ally abundant in the trucking district of Virginia and in a small district 
near Phoenix, .Arizona, during late February. This insect seriously 
injured turnips during March in Louisiana and southern Mississippi. It 
was also reported, during the latter half of June, from Nebraska. During 
later June it seriously damaged turnip in parts of Ohio and kohlrabi and 
radishes during May in the Norfolk -district of Virginia.

in a trucking district' of Virginia late in March. It seriously damaged 
red clover and co'. peas in. Illinois in June, it appeared in large •' numbers 
by the third week in., April in Kansas, by the third week in May was seri- 
ously injuring alfalfa in Kentucky, and by this time it was worse on the
