Two specimens of what we know as the potato Stell weevil (Trocho- 
baris trinotata Say) were taken by L. G. Gentner, scientific assistant, 
at Madison, Wis., May 25, 1920, which appears to be the first record of 
the insect in that State. They were found by sweeping in the vicinity of 
solanaceous weeds and probably the species does not attack potato thers 
In the work of eradication of thegsweet-potato weevil in the Charlton- 
Baker district of Georgia and Florida, B.L.Boyden writes that tne prevalence! 
of hog cholera on some of the farms in the Macclenny, Fla., region has 
rendered it impossible to “hog off" many of the fields, Beaause of this, 
rany sweet potatoes are left in the ground and the task of cleaning the 
fields is made much more difficult. 
J.E.Graf was in Washington during the holidays for consultation in 
regard to the sweet-potato weevil and Mexican bean beetle projects and 
afterwards attended the meeting of the Association of Economic Entomologists, 
where he presented a paper on the methods of eradication of the weevil. 
C.H. Popenoe attended the scientific meetings held in Chicago dur ing the 
holidays, after which he started on a tour of the southern States, investi- 
ing the Mexican bean beetle and sweet-potato weevil situation in that 
cat 
region.
