Nevada. G. G. Schweis (July 20): Newspaper articles have aroused much inter- 
est in the "black widow spider situation. Several specimens sent in have

species.

to our attention this season regarding black widows in and around Phoenix.

numerous in localities east of the Cascades. We have also received speci-

of its occurence west of the Cascades. 
CATTLE 
SCREW WORMS ( Coch lionyia spp. ) 
Georgia. R. A. Roberts (July 19): This insect is occurring in all directions 
beyond the area infested last year. Reports from the western edge of the 
infested area in Georgia have stated that the screw worn was active and 
causing losses in Muscogee County, on the Georgia-Alabama State line. 
On July IS a case of screw worms in a castration wound in a calf was dis- 
covered in Effingham County, Ga. This locality is about 25 miles north 
of Savannah and about 75 miles north of any previously recorded infesta- 
tion. The screw worn has spread into all the coastal counties of Georgia. 
Several cases were recorded in Long County early in the year, most of them 
having followed castracion u The present infestations are mostly on sheep 
and are due to tick "bites on the ears. 
F. C. Bishopp (Aiigust J,): It has been impossible to gather accurate 
information on the number of cases, but the total is several hundred and 
there is much anxiety over the situation.

numbers and severity in northern Florida. Hundreds of cattle and hogs 
and some horses have been lost.

Gadsden County.

cow in southern Okeechobee County. The county agent said that he had 
treated 25 cases since April 17. 
F. C. Bishopp (August 3): Reports have been received ^oy the Bureau 
that screw worn cases have occurred in Dade County, but the flies have 
not been reared. There are many cases in the northern part of the State 
and the farmers are much concerned over the situation. Reports show that 
the pest is attacking livestock further south than it did last year.

Florida indicate that the stable fly, known locally as the "dog fly", is
