Glyptoscelis pubescens (Fab.) occurs primarily east of the Mis- 
Sissippi River from Canada to Georgia and feeds on various 
species of pines and, reportedly, spruce and hemlock. The adult is 
oblong-oval, robust, broadly rounded posteriorally, dark brown 
with a brassy or golden sheen, and is from 7 to 10 mm. long. It is 
also sparsely clothed with an intermixture of white and brownish 
hairs. Adults feed on the edges of pine needles, causing them to 
turn brown. Damage has been reported in seed orchards of Vir- 
ginia, shortleaf, and white pines in North Carolina. G. barbata 
(Say) feeds on hickory and related trees from Connecticut to 
Pennsylvania. The adult resembles the adult of G. pubescens ex- 
cept that it is smaller and its upper surface is shining brown. 
Krause (440) reported on the genus Glyptoscelis in the United 
States and Canada. 
Many other chrysomelids also feed on various species of trees in 
the eastern United States. A few of these and their hosts are as 
follows: Pachybrachys peccans Suffr.—hickory and birch, P. 
tridens (Melsh.)—willow, P. othonus (Say)—ash and elm, and 
P. carbonarius Hald.—oak; Anomoea laticlavia (Forstr.)— 
honey and black locusts, elm, live oak, and mimosa; Tymnes 
tricolor (Fab.)—oak, walnut, and ironwood; Bassareus litur- 
atus (F.)—hickory; Derocrepis aescult (Drury)—buckeye; Pla- 
giometriona clavata (Fab.)—sycamore, basswood, and oak; 
Chlamisus platant Brown—sycamore; Xanthonia decimnotata 
(Say)—oak, beech, and elm; Paria sexnotata (Say)—red cedar; 
P. quadrinotata (Say)—walnut and mountain ash; and Syneta 
ferruginea (Germ.)—birch and oak. 
FAMILY LUCANIDAE 
STAG BEETLES 
Stag beetles are distinguished by their very large mandibles 
which, in the males of certain species, are branched like the ant- 
lers of a stag, and by the plates of the antennal club which are 
rigid and cannot be opened or closed. They are usually found in 
or beneath rotting logs or stumps. The larvae feed on the juices 
of rotting wood. 
The giant stag beetle, Lucanus elaphus Fab., the most familiar 
species, infests dead stumps in the South. Adults are large, fear- 
some insects, up to 60 mm. long. Male mandibles are branched 
and are more than half as long as the body. Pseudolucanus capre- 
olus (L.) is also a common species. It breeds in the trunks of old, 
partly decayed trees such as apple, cherry, willow, and oak. The 
adults fly at night and are frequently attracted to lights. Other 
eastern species include Platycerus quercus Web., Ceruchus piceus 
(Web.), Dorcus parallelus Say, and Sinodendron rugosum Mann. 
The first three breed in moist, almost completely decayed logs. 
S. rugosum breeds in decayed alder, willow, and poplars.
