now known to occur also in Massachusetts, Maine, Connecticut, 
Vermont, New York, and Pennsylvania. It feeds on a wide variety 
of species in the genera Thuja, Chamaecyparis, and Juniperus. 
Certain varieties of T. occidentalis and C. obtusa appear to be 
particularly favored. The adult is light brown with grayish wings 
and is about 6 mm. long. The beak is short, not quite as long as 
broad, and there are light, metallic green hairs on the legs and 
antennae. 
Eggs are deposited in the soil during May and June, and the 
larvae feed on the roots of the host plant for the remainder of 
the season. Winter is spent in the late larval or pupal stage, and 
the adults appear from early May to July (415). 
The arborvitae weevil is destructive in both the larval and 
adult stages, primarily in the larval stage. Damage in nurseries 
may be severe where infestations occur over a period of many 
years. In severely infested areas, well over 200 larvae may be 
found feeding on the roots of a single plant. This results in severe 
root pruning. 
Phyllobius oblongus (L.), the European snout beetle, an intro- 
duced species first recorded in the United States at Rochester, 
N. Y. in 1923, is now known to occur at least as far west as Ohio. 
It feeds on a fairly wide variety of hardwoods including elm, 
maple, willow, cottonwood, pear, apple, and plum. Adults feed on 
the leaves and young shoots of their hosts; the larvae feed on the 
roots of various plants. 
The Japanese weevil, Pseudocneorhinus bifasciatus Roelofs, an 
introduced species first recorded in the United States at Westville, 
Conn., in 1920, is now rather widely distributed in the North- 
eastern States. It feeds on a wide variety of trees and shrubs such 
as flowering dogwood, hemlock, red bud, azalea, rhododendron,
