( io\ eminent of Brazil imported 9 tons of Egyptian cottonseed. This 
seed was not fumigated, as it was not suspected that any injurious 
insect was likely to be carried by it. A test for germination showed 
89 per cent viable. It is altogether probable that a large percentage 
of the unviable seeds were those attacked by the pink boll worm. 
All of this seed was sent to agricultural inspectors in various States 
and by them was distributed further throughout the cotton-growing 
districts. There can be no doubt that the general establishment of 
the pink bollworrn in Brazil was due to the importation of the 
Egyptian seed, and that incalculable losses to the country could have 
been avoided if proper quarantine precautions had been taken. 
In 1911 two importations of Egyptian seed were brought into 
Mexico; one, of 25 sacks, was planted near Monterey, and the other, 
of 6 tons, in the vicinity of San Pedro, in the Laguna district. From 
what is known of the prevalence of the pink bollworrn in Egypt in 
1911 it is probable that both shipments of seed were infested and 
that both of them contributed to the present infestation in Mexico. 
It is true that cotton culture has not been continued in the vicinity 
of Monterey, but the crop of Egyptian cotton produced there in 1911 
attracted considerable attention and much of the seed was shipped to 
the Laguna district. 
In 1917, specimens of the pink bollworrn, collected by H. H. 
Jobson, were received from China. Eollowing is a quotation from 
Jobson's notes: 
The collection which I have was secured from the seed room of one of the 
ginneries in Shanghai and from the fields at Tungchow, about 12 hours' ride 
by boat up the river from Shanghai. The infestation is more or less gen- 
eral throughout China ; however', there may be some small areas where it is 
not present. A majority of the cotton grown within a radius of 100 miles 
of Shanghai is shipped into that port before being ginned, and from evidences 
found at the ginning establishments there is no doubt but what all those 
regions are infested. In fact, the larva? are so numerous that by going into 
the seed room of the gins a person may secure any number of them within 
a very short time, as they may be seen crawling around over the seed and 
on the walls. 
The infestation in Australia was first reported in 1923, from 
Queensland, and appears to have resulted from the carriage of cot- 
tonseed by soldiers returning from Europe to Australia, who stopped 
at Alexandria, Egypt. 
The infestation in the West Indies was apparently caused by a 
small shipment of cottonseed imported from Hawaii in 1911 to be 
used on the island of St. Croix for experimental purposes. 
PRESENT DISTRIBUTION IN MEXICO 
As far as is shown by absolutely definite evidence, the pink boll- 
worm in Mexico is confined to localities in the northern part of 
that country, one of them being the Laguna district, a valley isolated 
by mountain ranges about 200 miles from the Texas border. The 
Laguna, in which the greater part of the Mexican cotton crop is 
produced, consists of about 1,200 square miles of tillable land. 
Other localities known to be infested in Mexico (fig. 11, p. 26) are 
Allende (about 40 miles south of Eagle Pass), the Trevino Ranch 
(immediately opposite Del Rio), Santa Rosalia (in Chihuahua), 
Monclova, the Juarez Valley, and the area in Chihuahua opposite
