Delaware. L. A. Stearns (July 2U): Complaints received of i"-festr.tion 
on arborvitae at Hocl.esrin. 
ITorth Carolina. R. W. Lei"by (August ®): The bagworm is more injurious 
than usual on arborvitae all over the State. 
Ohio. T. H. Parks (August 23): Bagworms are still working on aroorvitae 
and. other ornamentals. 
Indiana.. J. J. Davis (August 2U): The bagworm has "been very much more 
abundant than usual and as far north in the State as Kokomo and La 
Fayette. 
Illinois. W. P. Flint (August 22): These insects have "been ouch more 
abundant and destructive than for any period in the last 6 or 7 years. 
They are now "becoming full grown in central Illinois. 
Kentucky. M. L. Didlake (August 23): Bagworms on evergreens are very 
aoundant at Lexington, Brooksville, Karlan, Anchorage, Baxter, and 
Hazard. 
Mississippi. C. Lyle (August 23): More than the usual number of com- 
plaints of "bagworm injury to aroorvitae and other shrubbery were re- 
ported from Aberdeen and Brookhaven.. Specimens have also "been re- 
ceived from Indianola and Shaw. 
Texas. F. L. Thomas (August 22): Bagworm found at Wharton, Belton, and 
College Station. 
SAT 1 27 MOTH (Stilpnotia salicis L. ) 
Washington. R. T. Webber (July): Infestations in residential sections 
outnumber those found in woodland. The principal woodland infesta- 
tions lie between Everett and E e llingham and are centered about the 
tributaries of the Stilaguamish and Skagit Rivers. Here willow ap- 
pears to be the most favored food plant. The largest single tract 
of practically complete defoliation noted is a few miles from Seattle 
in the Samish River Valley. This areaconsists of approximately 100 
acres and the growth is chief 1" willow. Other completely defoliated 
woodlands of an acre or more occur in Pierce and Cowlitz Counties. In 
these areas the native cottonwood ( Populus t richocarpa ) is the favorei 1 . 
food plant. 
A PSOCID ( Cerastipsocu s venosus Burm. ) 
Tennessee. G. M. Bentley (June IS): In all my experience I have never 
seen so many psocids on the larger branches of trees as this year.
