nany un sprayed trees had "been defoliated. In August it extended its range 
southward along the western side of the Sacramento Valley to Colusa County, 
and an isolated infestation was found at Port Costa, Contra Costa County, 
Calif. The infestation in the New England and Middle Atlantic States was 
considerably lighter than it has been for the last few years. 
A BASK BEETLE 
The discovery of great numbers of elm trees affected "by the Dutch elm 
disease in the New York, New Jersey, and Connecticut area and the proof 
during the past year that Scolytms multistriatus. Ikrsh. is able to transmit 
the organism causing this disease, melee the distribution of this insect a 
matter of especial importance at this time. Daring the fall of 1933, J.- N. 
Knull was employed by the Division of Forest Insects of the Bureau of Entomology 
and Plant Quarantine to make a survey of the distribution of the species. 
The records of this survey are presented in the accompanying map and the 
following list of localities. 
Connecticut . — Meriden, North Stamford, Noroton, Glenville, Brookfield, 
New I/Iilford, Naugatuck, and Fairfield. 
Mas sachus e 1 1 s . — Dover, Boston, Cambridge, Danvers, Wakefield, Halifax, 
South Hingham, Way land, Haverhill, and Newburyport, 
New Jersey . — East Orange, Princeton, Columbus, Flemington, Delaware, 
Bridgeville, Oxford, and Mount Pisgali. 
New York — Dodos Perry, Armonk, Jamaica, Roslyn, Bay Shore, Bronx Park, 
Tarrytown, Beechhurst, Peekskill, Bye, Fishkill, Croton-on- Hudson, 
Poughkeepsie, Staatsourg, Clermont, Bed Hook, Katonah, Port Chester, 
Bedford, Brewster, Cold Spring, Milton, Wallkill, Pine Bush, and 
Bloominghurg. 
Pennsylvania . — Stoverdcle, Baihbridge, Chalfont, Center Square, 'Test 
Chester, Beading, Hershey, Sunbury, and Bangor. 
The Division of Forest Insects is very much interested in obtaining all 
possible records of the occurrence of this beetle and, as other insects may 
also be able to transmit the Dutch elm disease fungus, this office will 
welcome notes on all insects attacking elm, especially if accompanied by 
specimens of the insects for identification. (William Middleton, Bureau of

Late in the summer of 1933 screw worms ( Cpchliomyia american a Cushing 
and Patton and C. macellaria Fab.) occurred as serious pests of livestock 
in a number of counties in southern Georgia and northern Florida. In May 
1934 infestations began to be reported in this general area, and as the 
season advanced the injury by the pests spread widely over the Southern 
States and appeared in isolated areas in the North Central States. At the 
close of the season the screw worms had appeared as important pests of live- 
stock in 57 counties in Florida and 120 counties in Georgia. In the southern 
third of South Carolina and throughout the southern half of Alabama, 
Mississippi, and Louisiana the infestation was also severe. Heavy losses
