The horned squash bug, Anasa a/*migera, was similarly abundant, 
and so numerous in individuals on many plants examined that they 
often outnumbered the common squash bug, A. //7st7/s, ten to one. 
The corn-ear worm, //eliothis armiger, was moderately destructive 
early in the season, and appeared later in great numbers, and in some 
places did considerable injury to late corn, tomatoes, and similar crops 
which it is known to affect. 
The cabbage looper, Plusia brassice, returned to this vicinity, and 
although rare early in the season, became quite troublesome to late 
cabbage. It seems probable that it is held in check, at least partially, 
in ordinary seasons by parasites and other natural agencies than 
weather. 
It was not expected that the harlequin cabbage bug, J/urgantia has- 
trionica, would increase to any observable extent, and this was borne 
out by the season’s observations, the species as a whole hardly ranking 
as an injurious one to crucifers other than horse-radish and very late 
cabbage. To horse-radish it was troublesome chiefly owing to the fact 
that drought also affected this plant, the crops suffering from the com- 
bined effects of the two factors. 
One genius of Noctuide ¢lassed with the cutworms and of omniy- 
orous tendencies, Prodenia, was noticeably rare in 1899, but the fact 
was not mentioned in the writer’s consideration of the Southern forms 
affected by the severely cold weather of the preceding winter. Two 
species were very abundant during 1897 and 1898, the moths being 
commonly found at lights, but in 1899 they were extremely rare. In 
1900, however, one form, Prodenia ornithogalli (lineatella) was fre- 
quently observed in the larval state in the field and more abundant 
on tomatoes than other crops, while the moths were not rare at lights. 
The other species, P. commelina, could not be found. 
The Southern cabbage butterfly, Pieris protodice, which was scarcely 
seen at all, except in the mature condition in a few individuals during 
1899, was found to have accumulated in great numbers at St. Elmo, 
Va., in the late fall. Mr. Pratt, who reported the occurrence, staced 
that next after the cabbage looper this was the most abundant enemy 
of crucifers in this region, occurring in about equal numbers on kale 
and turnips from the latter days of September throughout the month 
of October. 
The Southern tobacco worm, Protoparce carolina, also increased in 
great numbers, particularly during the latter part of the season, and 
was destructive to late growing tomato plants. The Northern tobacco 
worm, or tomato worm, 7. celeuws, it should be remarked, was rare as 
in the previous year. The parasites of both of these, as usual, were 
very abundant. 
The fall army worm, Laphygmna frugiperda, although it extends its 
distribution quite far north at times must be included in the category
