carrot beetle, as it is to carrot that it does most injury, although pars- 
nip, potato, and other root crops and some other cultivated plants are 
subject to its depredations. This latter has been quite prominent in 
recent years, and is therefore deserving of attention. 
Although the beet army worm has been destructive since 1899, there 
are some facts that have been learned in regard to it and its distribu- 
tion and origin that have not been recorded. Since sugar-beet grow- 
ing is Just now engrossing the attention of legislators and farmers in 
many sections of the country, it seems appropriate that as complete 
an article as possible in regard to this, one of the most important 
enemies of beets, be published. Three species of webworms, one of 
them more particularly destructive to the sugar beet, the second an 
introduced and important enemy of cruciferous cropsin the South, and 
the garden webworm, a species of omnivorous habits, have also been 
the occasion of considerable correspondence. 
Several species of insects injurious to cruciferous crops have been 
under observation. Hitherto no account of the red turnip beetle 
has appeared in Departmental publications; hence, an account based 
on injuries in the Northwest is presented. The insect is more par- 
ticularly destructive in the Dominion of Canada, but also inhabits 
the United States, and it seems probable that injuries will increase 
with time. This species is related to the Colorado potato beetle, and 
at any time an outbreak may be apprehended. The cabbage looper, a 
common pest throughout the South, and frequently making its appear- 
ance as far northward as Long Island in destructive numbers, has, 
after an almost complete disappearance, returned to the more northern 
points which it had previously invaded. It is considered in connec- 
tion with two related species, one of which is new as an enemy of cab- 
bage, and the other known as the celery looper. The cross-striped 
cabbage worm, or so-called ‘* cabbage Pionea,” has a similar distribu- 
tion to the common cabbage looper, and an account of it is also given. 
Some shorter notes are presented in regard to some cabbage insects 
whose habits have not been thoroughly studied, as well as some 
observations on insects affecting late cabbage and similar crops, the 
latter article forming the basis for an appeal for clean farming. 
A number of insects injurious to beans and other leguminous crops 
have been prominent during recent years, and four of these, the seed- 
corn maggot, the bean leaf-roller, the pea moth, and the bean cut- 
worm, are the subjects of articles. The remaining species are treated 
in an article comprising many subjects. It should be mentioned at 
this point that the destructive green pea louse continued its ravages 
during 1900, extending its depredations in the West particularly; but 
as this species has been given much attention by entomologists in 
Delaware and Maryland, the writer’s notes are withheld. What there 
was that seemed desirable for early publication was brought out in the
