Various ways of infecting trees with these fungi have been 
tried, such as spraying with water-mixtures of spores, rubbing 
with infested leaves, etc. The cost of infecting an orchard is 
very low and if properly done should pay well, particularly 
since the fungi in large areas are naturally more effective. 
There is a slight damage done the leaves of citrus trees by 
these fungi, but it is seldom of any importance. Indirectly, 
however, by hindering the use of fungicides in the orchard 
these fungi may be charged with some damage. 
Fungi under ordinary conditions and for a term of years 
have, unaided, controlled white-fly to the extent of about one- 
third absolute efficiency, the authors believe. 
There are in this Bulletin No. 102 of the Department of 
Entomology a number of original plates showing various stages 
of infection by the several fungi.

SEEKING FOR PARASITES OF THE ‘‘WHITEFLY’’ 
AND THEIR ATTEMPTED INTRODUCTION 
INTO FLORIDA 
R. G. WOGLUM 
UNITED STATES DEPARTMENT OF AGRICULTURE 
In 1910 the sum of $5,000 was set aside by Congress for 
investigation of possible parasites of the ‘‘whitefly’’ (Aley- 
rodes citri). Mr. R. G. Woglum was chosen for the errand, 
though he was at the time testing the efficacy of hydrocyanic 
gas in killing scale insects. He traveled through Southern 
Europe, Ceylon, and India, where he finally discovered a lady- 
beetle (Crytognatha flavescens motsch.) feeding on the fly. At 
Lohore, in the Punjab, an internal parasite was discovered 
which was named Prospaltella lahorensis. Living specimens 
were at length secured with difficulty and with these and a 
quantity of the ‘‘whitefly’’ food supply the return trip to 
Florida was attempted. Mr. Woglum succeeded in landing in 
Orlando, Florida, twenty-eight healthy lady-birds and some 
Prospaltella on December 2, 1911. Owing to the naturally
