INSECTS AFFECTING PARK AND WOODLAND TREES 529 



rull grown is about y 2 inch long. It is oval in shape, closely appressed to 

 the leaf, greenish and variably marked with red and pale orange, the latter 

 forming a pair Tff subdorsal stripes, in the course of which there may be 

 bright red blotches. Tubercles short and bearing numerous short spines. 

 This interesting caterpillar occurs on oak, chestnut, bayberry, Andromeda, 

 beech, sour gum, wild cherry and probably other deciduous trees. 



The life history of this group has- been the subject of careful and 

 painstaking study by Dr Dyar, and those interested will find his biologic 

 and bibliographic accounts given below of extreme value.
