In Charge of Truck Crop and Stored Product Insect Investigations. 
NOTES ON OCCURRENCE IN THE UNITED STATES. 
Receipts, in recent years, of stored products infested by the cos- 
sonine weevil CaulopJiilus latinasus Say (fig. 3) appear to indicate that 
it is permanently established as an enemy of dried cereals and other 
food materials in the United States. 
In December, 1895, the Bureau of Entomology received from the 
Cotton States and International Exposition, held at Atlanta, Ga., 
that year, specimens of this weevil 
found living in chick-peas (Cicer arie- 
tinum) from Mexico. 
February 3, 1899, living beetles were 
found in about equal numbers with the 
rice weevil in shelled corn and chick- 
peas purchased by Mr. August Busck 
from a store at Arroyo, Porto Rico. 
December 3, 1902, Mr. A. L. Her- 
rera, City of Mexico, Mexico, sent a 
sample of stored corn from Tlaxiaco, 
State of Oaxaca, infested with this 
species, which had been previously 
identified with injury of this nature in 
Central America. 
During February, 1909, the Bureau 
of Entomology received from Mr. P. J. 
Wester, Bureau of Plant Industry, several seeds of avocado, or alli- 
gator pear (see fig. 4), obtained at Miami, Fla., via Jamaica, infested 
with numbers of this weevil. 
By April 28 the seed centers had become reduced to powder by the 
weevils and were filled with larvae and pupae, while the adults were
