TRIBE I. — GALEATINI. 459 



Common in Indiana wherever the sycamore grows. Occurs 

 throughout the year, hibernating beneath bark of sycamore 

 and nearby cover, and in spring and summer feeding upon its 

 foliage, often causing the leaves to wilt and become whitened. 

 Known as the "sycamore lace-bug," and ranges from Quebec 

 and New England west to the Rocky Mountains and southwest 

 to Alabama. Occurs also on ash, hickory and mulberry.
