1106 General Notes. [ November, 
for much kindness during a short stay at Cordova, I obtained the 
following information regarding the destructive locust of that 
region. Within the last two or three years locusts have devas- 
tated portions of Central America, and for two years past they 
have extended over nearly the whole of the States of Vera Cruz, 
Oaxaca, Chiapas, Morelia, Michoacan and the intervening coun- 
try to Matamoras. Dr. Russell lost perhaps $3000 worth of 
coffee trees on his plantation, and in a single year spent nearly 
$1000 in fighting locusts. 
According to his statements the swarms of locusts arrive from 
Central America over a period lasting from April to November, 
viz., from seed time to harvest. They deposit their eggs in April 
and May, the young hatching in from twenty to thirty days, and 
becoming fledged in three months. The young locusts do the 
most harm, and travel in dense masses, sometimes six inches 
deep, leaving the ground behind them black, as if burned by fire. 
They are often so thick in the roads that the horses will slip and 
slide over their crushed bodies. They are particularly destruc- 
tive to the young coffee plants, gnawing off the bark from the 
young trees and from the tender branches of large trees, but they 
do not eat the leaves. Oranges, palms, corn, rice and tobacco 
plants also greatly suffer from the attacks of this locust. Unfor- 
tunately no specimens could be obtained so as to learn which 
Species does this wide-spread damage. It is probable that the 
insect is Acrydium americanum, as we have received specimens 
from Yucatan. For other accounts of the ravages of locusts ‘in 
Central America and Mexico, see first report of the U. S. Entomo- 
logical Commission, pp. 460-465; also third report, appendix,
