The horned squash bug, Anasa armigera, was similarly abundant, 

 and so numerous in individuals on many plants examined that they 

 often outnumbered the common squash bug, A. tristis, ten to one. 



The corn-ear worm, Ileliothis 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, Plnsia orassicce, 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, Murgantia his- 

 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 Noctuidas classed with the cutworms and of omniv- 

 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 omithogalli (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. commelince, 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, 

 Ya., in the late fall. Mr. Pratt, who reported the occurrence, staled 

 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, P. celeus, 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, Laphygma fragiperda, although it extends its 

 distribution quite far north at times must be included in the category
