Orlando. In 1906, E. W. Berger found it on a few whitefly larvae at 

 Leesburg, Florida. 



The effect of this parasite upon Aleyrodes citri seems-tobe of little 

 practical value. It has only rarely been observed attacking this insect, and 

 then does not occur in quantity, as do the other fungi before spoken of. It 

 is not uncommon to find a large amount of this fungus upon Mytilaspis 

 citricola in trees that are at the same time infested with larvae of Aleyrodes 

 citri on which no fungus can be found. 



LIST OF INSECTS PARASITIZED. 



A list of insects reported to be attacked by this fungus is here given, 

 together with the authority for the report and the localities in which they 

 were found parasitized :

 of the branches, one and two-celled, oval to oblong, 7 12X3 microns;
