tomatoes. It was first brought to the writer’s attention in July, 1898, 
by Mr. T. A. Carroll, of Gainesville, Fla. Specimens which were 
received at that time were fed here upon tobacco through the remainder 
of the season. The eggs have not been found, but two generations 
developed between July and the killing frosts, on which date the bugs 
disappeared, hiding away in the full-grown condition for hibernation. 
The different stages of growth observed are shown in fig. 12. The 
species has been studied to better advantage in the field by Mr. 
Quaintance in Florida, who considers it a serious enemy of the crop,

and states that it has been known to growers in Columbia County for 
the past ten years. The first crop is generally not damaged to any 
serious extent, but the second crop and late tobacco are frequently 
quite destroyed. Mr. Quaintance also states that the insects make 
their appearance in injurious numbers during the first and second 
weeks in June, and that the full-grown bugs are first noticed in some 
restricted portion of the field, as on the plants in one corner, from 
which they gradually move over the field. They have been observed 
on neglected tobacco as late as November 22.
