22 THE FLORIDA ENTOMOLOGIST 
(1913-1915) and during all seasons. They represent those found 
on both cultivated crops and wild plants. The former, of course, 
are brought to the attention of economic workers much more 
often because of their importance to agriculture and also their 
greater abundance. The list represents about 30 species of 
aphids. Many others collected could not be determined because 
of lack of mature specimens or winged forms. Undoubtedly 
there are in the state many undescribed species of plant lice 
and at least two of these were found. 
Permanent mounts were made of all specimens and are in the 
author’s collection. Natural colors cannot be retained in mount- 
ed slides and color notes must be made from the live specimens.
