300 
miles south of Eagle Pass (see map), on the Mexican International 
Railway. It was known in this locality long before it was heard of 
elsewhere in Mexico. 
Don Jesus R. Rios writes me, from information he has received from 
Monclova, that the weevil first appeared there in 1856. For six years, 
from 1856 to 1862, it was so bad that cotton planting was abandoned 
thereafter in that district. The insects were said to appear there in 
the. fields as early as May, and by July to have completely infested the 
crop. I received information from another source stating that the 
weevil was known in Monclova as early as 1847, and in Matamoras as 
early as 1851, but I am inclined to believe that my informant was mis 
taken in the insect, and that these data refer perhaps to the boll worm. 
Maj. B. Coopwood, who was engaged in cotton raising at Hermanas, 
Coahuila, in 1867, informed me that the weevil was known there in 
that year, and that it destroyed much of the crop. He stated that it 
appeared about the last of June or first of July. 
In Sabinas the weevil has been known to be injurious for three years. 
At San Juan Allende, Morelos, and Zaragoza, it was not known until 
1894. At Zaragoza the weevil was first seen in the fields, according to 
Mr. Rios, the last ot July, but in Allende not until the last of August. 
When it first appeared in Matamoras is uncertain. Mr. H. Nielsen, 
of that city, writes me that he has known of it in that locality for the 
last few years, but in less numbers this year. 
From Matamoras it came across to Brownsville, and within the past 
two years or more spread north into the whole cotton region of south- 
ern Texas. 
The Agricultural Department received the first notice of the inju- 
rious nature of this insect about ten years ago, when Dr. Edward 
Palmer sent specimens from the state of Coahuila, with the information 
that they were bred from cotton bolls. 
In the neighborhood of Matamoras a good deal of cotton has been 
raised for the past ten years, but I am informed that not much was 
raised before that. At Zaragoza and Allende cotton has been raised 
for many years. In the San Diego region it has been cultivated in 
any quantity for only four or five years. 
PRESENT SPREAD IN TEXAS. 
At present this weevil is known in the Brownsville region, and 1 
found it December 10 in all the cotton fields along the stage road up 
to 36 miles north of Brownsville. No fields were to be seen on the road 
beyond that. It is reported also to be as far up the Rio Grande on the 
Texas side as Hidalgo, but this needs verification. 
It occurs from Corpus Christ! to Benavides, along the Mexican 
National Railway, particularly around San Diego and Alice. It is 
known for 20 miles north of San Diego; at Amargoza, about 12 miles 
northeast of San Diego, and at La Rosita, 12 to 18 miles west of the
