[60] REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 
No. 114.] United States Consulate at Merida, 
November 22, 1879. 
Sir: I have the honor to acknowledge receipt of your dispatch of October 13, 1879, 
having received the inclosed copy of the letter from the Chief of the Entomological 
Commission, addressed to the Honorable the Secretary of the Interior, and in compli- 
ance with the contents of said letter, I beg leave to give the following information: 
The culture of cotton is very little here ; it is cultivated only in the southern part 
of this city, and in very small quantity. It grows to the extent of 12 feet. 
No other insect enemies of the cotton plant are known but its worms, and this 
worm is exactly as mentioned in the letter, that is, a green worm with white lines and 
black dots. 
This worm is always on the cotton leaf, and there is no doubt that by eating the leaf 
greatly helps to kill the plant. He does not toucli the acorn of the cotton, as he re- 
mains always on the leaf. If possible by next opportunity I will send specimens in 
alcohol. 
Cotton has been growing here for more than sixteen years, and grows wild, but is 
inferior to the plant cultivated. 
The prevailing directions of winds during the months of March, April, June, and 
July, are generally breeze and southeast. 
Any more information that I may have about the Cotton Worm and the insect 
enemy of this plant, I will transmit immediately.* 
I am, Sir, your obedient servant, 
M. CEBALLOS, 
United States Vice-Consul.

No. 22.] United States Consulate at Tampico, 
November 25, 1879. 
Sir: I have to acknowledge receipt of your separate dispatch dated October 13, 
1879, and inclosing a copy of a letter from the Chief of the Entomological Commission, 
addressed to the Honorable the Secretary of the Interior, under date of October 6, 1879. 
In pursuance of your instructions I answer as follows, and in their respective order 
to the points as given in the letter aforesaid, to wit : 
1. Cotton has never been grown to any extent in this district ; however, the several 
attempts made at its culture have proved agricultural successes. The plant is known 
to keep four, sometimes five years, producing a first crop, which for its superior qual- 
ity might be classed middling fair. The successive crops declining in quality and 
quantity. Two crops can be gathered in eighteen months. 
2. Besides the caterpillar, which is said to be larger than that of the United States, 
the plant here has another very destructive enemy in the large brown emmet, com- 
monly named here arriera. 
3. The caterpillar invades the cotton fields of this country in about the same man- 
ner as in the United States. The worm, if I am correctly informed, is of a dark green 
color, with jet black eyes; is larger than ours and with no white lines nor black dots. 
It generally appears in the dry season. 
4. The worm is not believed to be imported, it being known to exist in this coun- 
try ever since the cotton plant was discovered. 
5. The plant was found growing wild by the Spanish conquerors. 
6. The wind generally prevails in the easterly direction (sea breeze) all the year 
round in this district. In the winter months it is occasionally visited by strong 
northers. 
7. I have already written for a specimen of the worm, which will be forwarded as 
soon as practicable* 
I am, sir, your obedient servant,

United States Consul.
