were experienced in the coastal region 02 Texas, thus connecting the newly 
infested area in the Southeast with the normally infested area in Texas. The 
number ox screw worm cases in the western "art of Texas and west-;: rd through 
Hew Mexico, Arizona, and California during 1934 was apparently somewhat "below 
normal for that region. This wrs due doubtless in a large ©art to the 
drought. The appearance of the screw worm as a -oest of livestock in north- 
western Iowa and southern and central Indiana is noteworthy. The infestation 
in Iowa centered in Plymouth County and extended into VJoodbury and parts of 
Monona and Cherokee Counties. Veterinarians reported that they treated about 
330 cases in low?.. The screw worm" was present in limited numbers in the 
vicinity of Sioux Falls, S. Dak. Specimens collected from wounds from a 
number of cases were definitely identified "by E> P. Knipling as C_. americana . 
In Indiana, definite records of screw worm' occurrence were obtained from 
Lawrence, Hendricks, and Montgomery Counties, Specimens reared from wounds 
proved that C_. amcricana was involved. 
A "brief survey of south-central and western Tennessee "by 0. G. Babcocfc 
late in the season indicated that a limited number of cases occurred in that 
area, and a survey made by E. '7, Laake in southern Louisiana showed that the 
infestation of cattle in seven parishes ranged ' from .1 to 15 percent. The in- 
festation among horses and mules in the same area was found to have the same 
percentage range. The infestation among' sheep ranged from 1 to 40 percent 
and among hogs from 3 to 25 percent. 
Accurate figures on the number of cases occurring in different types of 
animals were obtained by D. C. Parman and his associates in 21 counties in 
southern Mississippi. This survey indicated' that 12 percent of all animals 
in the counties were infested, the percentage .by different species of animals 
being as follows: Cattle 11, sheep 15, goats. 6, horses and mules 9, hogs 
11, and dogs 14. Somewhat similar percentages of infestation were reported 
from Georgia by W. E. Dove and from Florida by 77. V. King. 
It has been found practically impossible to arrive at a reasonably 
accurate estimate of the death loss of livestock in invaded territories. 
Reports obtained from a considerable numoer of county agents in Georgia in- 
dicated the death loss in 86 counties of that State to be over 50,000 head.

BUFFALO GNATS .... 
A heavy infestation of Buffalo gnats ( Simulium s-:p.) occurred in the 
Ohio Hiver bottoms of Kentucky and in east-central Arkansas during the last 
week in April. In Arkansas 100 head of mules were killed in one county alone 
and the total number of deaths in the State was estimated at 503 head.
