Enemies of stored vegetable products. — An effort was made to obtain 
specimens of certain enemies of grain and other stored products in 
Mexico. Several species belonging to the Ptinida 4 , Bruchidae, lihyn- 
chophora, and Lepidoptera, are of much economic importance from the 
injury they would do if introduced into the United States. 
A number of species were obtained in stored corn, etc. 1 
EXTENT OF CLIMATIC AND FRUIT REGIONS. 
In the region of the western coast of Mexico the warmer belt adapted 
to the subtropical fruits extends much farther north than it does in the 
eastern coast region at the same elevation above the sea. 
Date palms grow luxuriantly at Guaymas and Hermosillo, and even 
as far north as Magdalena in Sonora. They can not do well in Chihua- 
hua, which is nearly as far south as Guaymas, nor even in Aguas Cali- 
entes, which is well within the tropics. The latter place, though only 
about t>,000 feet above the sea, has been known to receive snow falls. 
Magdalena, in Sonora, though but little south of 31° K., is nearly the 
same temperature as (or warmer than) Monterey, which is about the 
same distance south of 20° ¥., and both places are at nearly the same 
elevation. This represents a difference of 300 miles in a north and 
south line. Date palms grow well at Matamoras, however, which is 
near the coast and much farther south than the Sonora date-producing 
region. 
Oranges grow and produce exceedingly well at Guaymas (San Jose 
de Guaymas) and Hermosillo. They also seem to do fairly well at 
Magdalena, though there are very few at that place. There are more at 
San Ignacio, a small town about six miles north of Magdalena on the 
railroad. The Hermosillo oranges have the reputation of being among 
the finest in the world. In Chihuahua (neighborhood of city) oranges 
cannot be raised, the winter frosts being too severe. A few trees are 
to be found in the city, but only in sheltered patios (interior courts 
of houses), and none in any of the plazas. A very few oranges are 
raised at Aguas Calientes. At Monterey some few are raised, and south 
toward Victoria there is quite an extensive orange-producing region, 
notably at Montemorelos and Linares, particularly the former. Oranges, 
and especially limes, are raised at Victoria, and all the region between 
that place and Tampico would form a splendid district for the produc- 
tion of citrus fruits if a sufficient water supply could be secured. In 
the Guadalajara region a good many oranges are raised in the barrancas 
(deep ravines) to the west, but they are extensively produced in the 
Lake Chapala region south of La Barca, which is less than halfway 
between Guadalajara and Irapuato, on the main line of the Mexican 
Central Kailroad. Then again, in the State of Morelos, south of the 
City of Mexico, in the low valleys or hot lands, oranges are raised prin-
