Halisidota carycs Harr. Larvae very abundant in the rich woods 

 of maple, birch, etc., wandering about in search of suitable 

 places to make their cocoons. The caterpillar of this species, 

 known as the Hickory Halisidota, and that of H. maculata, 

 known as the Spotted Halisidota, were extremely abundant 

 in Canada and northern United States in August and Sep-- 

 tember. Much anxiety was felt by fruit growers and others 

 in districts where the caterpillars appeared in great numbers. 

 The writer published an account of this outbreak in the 

 Annual Report of the Entomological Societv of Ontario, 

 for 1907.
