SEVENTH ANNUAL MEETING OF THE. 
Injurious Insects. 
Paper read by Prof. P. H. Rolfs, of the Agricultural Experiment 
Station, Lake City, Columbia county, Chairman of Standing 
Committee on Entomology. 
After receiving the notice from your honorable ex-secretary, 
Mr. Hart, much thought was put on just what the nature of 
the report on entomology should be. After the field had been 
carefully considered it became clear that I would not be serv¬ 
ing the Florida State Horticultural Society nor the state to 
the best of my ability, by bringing here correctly named spec¬ 
imens and fine stereopticon views to illustrate important in¬ 
sects under discussion, nor by presenting some new device or 
insecticide for slaying our insect enemies by the thousands^ 
Ladies and gentlemen—This way of treating the subject has 
been in vogue since the organization of the society; the 
speeches have been good; often considerable time had been 
spent in their preparation. These discussions have been con¬ 
fined to insect enemies that were in the state. Let me pre¬ 
sent to you three insects that we have not, and one that has 
barely put his foot on Florida soil. 
THE OLIVE POLLINIA. 
The olive industry is just beginning to attract some atten¬ 
tion in this state. Much has been written and said of it in 
California. New and promising varieties have been intro¬ 
duced from Europe. Recently it has been discovered that 
with this importation from Italy there has been brought in 
also the olive pollinia, pollinia costae targ. This scale insect 
so closely resembles the bark that it will not be detected or¬ 
dinarily. It is particularly dangerous in that the usual washes 
or insecticides do not destroy it. In passing I may mention 
that there are several other insects in Europeon the olive that 
have not yet found their way to America. The polliniajis a 
serious pest even m Europe, where labor is cheap and its^ene- 
mies present to checkmate it. 
THE GYPSY MOTH. 
(Ocnena Dispar .) 
This most destructive pest was brought to this country by 
Mr. L. Trouvelot, now of Paris. Mr. Trouvelot was at the
