hire, who has published a very full statement on the subject (8). 
During 1913 Mr. Green made a trip of inspection through the greater 
portion of the cotton-producing area in Brazil. Special attention 
was paid to the seed, not only in the fields but in the ginneries, and 
no infestation was found. In 1916, however, another trip showed 
that the pink bollworm was present over wide areas in the States 
of Parahyba, Rio Grande del Norte, and Ceara. It seems that in 
the years 1911, 1912, and 1913, the Government of Brazil imported 
nine tons of Egyptian cotton seed. 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 al- 
together likely that a percentage of the unviable seeds were those 
attacked by the pink bollworm. All of this seed was sent to agri- 
cultural 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 
bollworm 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 Mexico the pink bollworm was introduced in 1911. During that 
season two importations of Egyptian seed were made. One consisted 
of 125 sacks and was planted near Monterey; the other, of 6 tons, 
and this was planted in the vicinity of San Pedro in the Laguna. 
From what is known of the abundance of the pink bollworm in 
Egypt in 1911 it is probable that both shipments of seed were in- 
fested and that both of them contributed to the present infesta- 
tion in Mexico. It is true that cotton culture has not been con- 
tinued 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. 
The work of determining the spread of the pink bollworm in 
Mexico was greatly facilitated by the cooperation of the Mexican 
Government. The Minister de Fomento, Sr. Pastor Eouaix, Sr. 
Jose Duvallon, Director de Agricultura. and Prof. Julio Requelme 
Inda of his department, showed the greatest interest in the matter 
as soon as the presence of the pink bollworm in Mexico was known. 
Sr. Duvallon dispatched a special representative, Sr. Alfonso Mada- 
riaga, to Northern Mexico, where he spent some months in making 
examinations in the Laguna. His findings corroborated in every 
way the discoveries made by Mr. Busck. 
Very recently specimens of the pink bollworm have been received 
from China. They were collected by Mr. H. H. Jobson, who at the 
present writing (May, 1918) has just returned from China. Mr. 
Jobson's notes are as follows :
