on the underside of leaves, and the larvae feed almost entirely 
within the tissues of the leaf, forming large blotch mines. Pupa- 
tion occurs within the mine and new adults appear in August. In 
heavily infested areas, they may crawl over buildings in such 
large numbers as to be a nuisance (553). The apple flea weevil, 
Rhynchaenus pallicornis (Say), feeds on apple, hawthorn, 
winged elm, hazelnut, and quince from New York to Illinois and 
Missouri. Adults are black and about 2.5 mm. long. 
Rhynchophorus cruentatus (F.), the palmetto pill bug, occurs 
from North Carolina to Florida and Louisiana and breeds in the 
trunks of weakened palm trees and cabbage palmettos. The adult 
has a red thorax with black margins, shiny black wing covers, 
fringes of long yellowish hairs on the legs, and is 29 to 30 mm. 
long. It feeds on bruised terminal buds or on sap exuding from 
wounded or recently felled trees. 
Several species of Attelabus L. feed as leaf-rollers on the foli- 
age of various trees and shrubs in eastern United States. Adults 
are robust and from 3 to 6 mm. long. The beak is flat and about 
as long as the thorax; the color is usually dull red to black; and 
the elytra have rounded tips, leaving the last abdominal segment 
exposed from above. The female cuts a slit from each edge to the 
midrib of a leaf and then rolls the portion beyond the slit into a 
solid roll. One or more eggs are deposited in the roll. The female 
then gnaws the petiole partly in two, and the leaf eventually falls 
to the ground. The larvae feed on the inner parts of the roll and 
eventually pupate in the ground. A. analis Ill. and A. bipustulatus 
F. commonly occur on oaks, hickories, and walnut; A. nigripes 
LeC., on sumac and hickory; and A. rhois Boh., on alder and 
hazelnut. 
Adults of the genera Cimberis and Diodyrhynchus feed on the 
staminate flowers of various pines and other conifers from Can- 
ada to Florida. They are usually dull red, have flat snouts which 
are about as long as the thorax, and are usually less than 5 mm. 
long. Several species of the genus Hugnamptus feed on the leaves 
of various hardwods. Dryophthorus americanus Bedel occurs very 
commonly in hickory killed by the hickory bark beetle. Stenoscelis 
brevis (Boh.) is common in dead, dying, and rotting hardwoods. 
The subfamily Cossoninae, the broad-nosed bark weevils, con- 
tains several genera and many species. A number of species breed 
in the sapwood of hardwoods and conifers killed by bark beetles; 
others, some of which are important pests, breed in the woodwork 
of buildings. The larvae of all species cut meandering galleries 
across the grain of the wood and pack them tightly with granular 
frass except for that portion immediately behind their bodies. 
Adults may be found in the wood, but they usually occur under 
the bark about a year after the tree is killed. Anderson (10) 
described the larvae of a number of species. 
Several species in the genus Cossonus Clairville breed in the 
sapwood of bark-beetle killed trees. C. corticola Say, a shiny black 
species—under the bark of dying pines; C. platalea Say, a flat, 
shiny black species—under the bark of hardwoods; C. impressus 
Boh., a dull black species,—in the sapwood of both conifers and 
hardwoods (reported from Florida) ; and C. cossonus Boh. and 
C. impressifrons Boh.—under the bark of hardwoods.
