FOREST TENT CATERPILLAR ( Mai aco som a disstria Hbn. ) 
Virginia Wm. Middle ton (May 8): On May 31, 1930, I reported the 
activities of the forest tent caterpillar which was defol- 
iating most of the trees over considerable areas in Bucking- 
hair County. I have just received a letter from Mr. L. T. 
Steger of Warren on whose farm I first observed the activities 
of this caterpillar. Mr. Stegar reports that the cater- 
pillars have reappeared this year by the millions and are 
playing havoc all through this section, webbing from the 
limbs to the ground and to housetops, literally covering 
the houses and ground. 
W. J. Phillips (May 15): There is a serious outbreak of 
the forest tent caterpillar in the neighborhood of Scotts- 
ville, Fluvanna County. Several hundred acres of forest 
land have been entirely defoliated. Mr. Maddox, the Assist- 
ant State Forester here, informs me that a like outbreak is 
in progress in Buckingham County. This is the worst out- 
break I have ever witnessed.
