face the most severe outbreak in a number of years. Hail storms and 
floods have killed large numbers of livestock and wild animals, there- 
fore the population of the secondary screw worm fly (C. macellaria Fab. ) 
has "been increased enormously. In addition to injuring livestock "by 
infesting wounds initiated by the primary screw worm fly (C. americana 
Cushing and Patton) , C. macellaria has attacked the fleece of many sheep 
whose wool has "become sour or foul as the result of "being kept wet 
"by continued rains. In Georgia screw worm cases have "been reported from 
110 counties "but the number of cases in any one county is not large, 
1^0, reported from Thomas county, "being the maximum number. As it was 
not possible to examine all the cases, the species of fly causing the trou» 
ble was not determined. Twenty cases attributed to screw worms were re- 
ported from 10 counties in South Carolina for the week ending June 22. 
Specimens of larvae were not obtained in these cases and the species 
involved was not determined. In Louisiana, Mississippi, and Alabama the 
infestations are comparatively few. Records obtained from Jefferson 
Davis and Calcasieu Parishes, La., report 77 cases for the week ending 
June 22; however, it has been determined that some of these infestations 
were due to Phormia regina Meig. For the same period 36 counties in 
Mississippi reported 116 cases, and in Alabama S$ cases were reported 
from 35 counties. The most severe outbreak of screw worms in the South- 
east is in Florida. The number of cases is rapidly increasing and the 
flies are spreading to new localities. The heaviest infestations occur 
in the central counties. The total number of infestations in the State 
has been reported as 23,000, with Sumter County having 2,500, the max- 
imum number for any one county.
