TRANSPORTING ENEMIES OF WHITE FLY TO UNITED STATES. 37 
orange trees infested with larvae of the white fly. By October 13 
the coccinellid larvae were in large number and a week later adults 
had become numerous. 
This coccinellid feeds upon the eggs and larvae of the white fly. A 
few cases have been noted in which pupae were attacked. They do 
splendid work when the proper food is in abundance. The most 
extreme instance of efficient performance by this lady-beetle was 
observed on some young potted orange trees severely infested with the 
white fly in the larval condition. About thirty of these trees were 
grouped closely together in the shade of a large overhanging tree in the 
Lahore Botanical Garden in order to secure infestation with parasites. 
Within a period of 10 days these trees had become inhabited by so 
many lady-beetle larvae that the white flies were largely destroyed and 
the trees were rendered useless for the writer's purpose. This insect 
has been collected by the writer in the Eastern United Provinces 
and the Punjab. 
Pkeparation of Beneficial Insects for Shipment. 
The coming of the rains during the latter part of August, which 
resulted in the emergence of the fall brood of the citrus white fly and 
subsequent infestation of the young potted trees, marked the begin- 
ning of a period of steady progress toward successful accomplishment 
of our endeavors in India. Closely following the hatching of the first 
white-fly eggs numerous specimens of Prospaltella lahorensis could be 
seen walking around on the leaves of the infested young trees. By the 
middle of October it was evident that many aleyrodid larvae had been 
parasitized. Fortunately large numbers of the coccinellid Cryp- 
tognatlia flavescens had appeared simultaneously with the internal 
parasite. 
Believing it to be the ideal time for preparing the shipment, five 
cases were packed on October 18 with aleyrodid-infested trees. Each 
of the cases contained between 10 and 20 trees. Three cases were 
filled with material parasitized by Prospaltella, while each of the other 
two cases contained about 150 specimens of the lady-beetle Cryp- 
tognatha. The lady-beetles were in both the larval and adult stages. 
Transporting the Natural Enemies of the Citrus White Fly 
from India to the United States. 
On October 20, 1911, the five cases of natural enemies of the white 
fly, together with a sixth case, which contained several valuable 
varieties of citrus fruit trees native to that country, were placed 
aboard a train at Lahore and started on their long journey to America. 
(Plate X.) At Bombay the shipment was placed aboard a vessel 
bound for Europe. As there are no through steamers between 
Bombay and New York, it was necessary to transship to other vessels
