Oklahoma. C. F. Stiles (Au^rust 22): One of tie small blood-sucking midges, 
which belongs to the family Chironomidae, has been reported from Fot- 
tawatomio County, near Dale. These insects have been causing consider- 
able annoyance and damage to livestock, such as horses, mules, and 
cattle. The chief remedy at this time seems to be keeping the livestock 
in barns at night. This insect is breeding in the North Canadian River, 
into which the sewage of Oklahoma. City is being dumped. The river is 
very low at this time, and the midges can be seen there by the millions 
at about dusk each evening, and they annoy livestock throughout the en- 
tire night.
