SPRING AND SUMMER NUMBERS 65 
THYSANOPTERA OF FLORIDA 
(Continued from page 55) 
lector is not indicated, the collection and identification are those 
of the writer. 
This should be considered as preeminently only a preliminary 
list and by no means complete. It is thought, however, that it 
includes all species that have been recorded in entomological 
literature as occurring in the State. The only locality in which 
the writer has done systematic collecting is that about Gaines- 
ville, and even this small area is by no means exhausted. 
Nevertheless the list contains more than four times as many 
species as Smith lists in his “Insects of New Jersey’. When 
one considers that in most orders of insects the New Jersey list 
is much larger than the corresponding one of Florida (not be- 
cause New Jersey has more species but because it has been more 
thoroly worked than Florida), it becomes evident that Florida 
is rich both in species and individuals as compared with states 
further north. 
In addition to notes on the distribution, food plants, season, 
and habits of our Florida species, this list contains keys to the 
species in general to which the author has added new species. 
This seems desirable because no adequate keys are in existence. 
These keys have in most cases been modified from those of other 
authors and unless otherwise indicated from Moulton (1911). 
There has been appended bibliography of those works found 
most useful in the study of our Florida species and all papers 
in which Florida captures have been recorded. Any one wish- 
ing to identify our species for himself should be able to do this 
by means of this list and Moulton’s work (see bibliography, 
Moulton, 1911).
