20 REPORT OF SEARCH FOR ENEMIES OF CITRUS WHITE FLY. 
Discovery of the Brown Fungus, zEgerita webberi. 
During this examination of the Saharanpur region the writer's 
attention was frequently called to the presence of a brownish fungus 
attacking the white fly on trees in well-shaded positions. It seemed 
identical to all appearances with the Florida brown fungus (lEgerita 
webberi), yet hi order to be certain in this determination a quantity 
was sent to Prof. H. S. Fawcett, formerly of the Florida Agricultural 
Experiment Station, an authorhyy on fungous diseases of the white 
fly. His identification of it as Mgerita webheri was conclusive in 
showing that this fungus occurs in India as well as in Florida. 
The writer failed to find this fungus except in the region about 
Saharanpur. A great deal of exchanging of plants, especially of 
citrus trees, between the botanical garden at this place and certain 
nurserymen in Florida has been going on for many years, and it 
seems quite likely that the brown fungus was introduced from 
Florida into India through these exchanges. 
Searching at Lahore. 
Leaving Saharanpur on November 10 the search was continued 
northward into the Punjab, and Lahore, the principal city in this 
Province, was made temporary headquarters. It is located toward 
the center of a broad plain and is less than 500 feet above sea level, 
although more than a thousand miles inland from the ocean. The 
plain is bordered on the north and east by the gigantic Himalayas, 
while it opens southward in an unbroken stretch to the sea. The 
climate is general!}' dry, the temperature of the summer being exces- 
sively hot, frequently reaching to between 115° and 120° F., while 
the winters are comparatively cold, the minimum temperature 
averaging between 35° and 50° F. It is very seldom that the tem- 
perature falls below 35° F. 
Orange trees are abundant at Lahore, beiug found in almost every 
yard, as well as being the most common plant used for hedges. In 
the vicinity of this city they are grown to a considerable extent for 
commercial purposes. This consideration, coupled with the induce- 
ment offered by the presence of a large botanical garden, led to the 
decision that Lahore was the most suitable situation hi the north for 
continuing our efforts, and later developments resulted in demon- 
strating it to be the most suitable locality in all India. Considering 
the abundance of orange and lime trees as well as their diverse con- 
ditions of cultivation, existing, as they did, from dense growths of 
seedling trees, entirely uncared for, to well-cultivated orchards of 
healthy budded stock, it seemed that if the white fly and natural 
enemies were to be found anywhere in northern India this must 
be the place.
