Rkd-cockaded Woodpecker {Dryobates borealis). 
Contents from eleven adults of both sexes — Six egg-cases of a small cockroach 
{Ichnoptera). The egg-cases of these small tree-inhabiting roaches are usually de- 
posited behind the loose bark of trees. Three skins of coleopterous larvse ; judging 
from their last joints they belong to the genus Tenebrio, the larvse of which are 
found under dead bark. One leg of Pachylobious picivorus ; this snout-beetle is 
common throughout the south, and is found upon the diflerent species of pines. 
Eight elytra of a beetle ( Cymatodera undulata or brunnea) . These beetles are also 
found under bark of living and dead trees; their larvse live upon other insects. 
One small pupa of a Cerambycid insect ; it is probably the pupa of a Liopus or 
Sternidius : both species breed in decaying twigs. One small larva of a Cerambycid 
insect, not recognizable. One egg of a large hemipterous insect, probably that of 
Brachyrhynchus granulat us., Say- Numerous legs of spiders and bugs. Two skins 
of spiders, partly digested and squeezed out. Skin of a dipterous larva. Several 
specimens of a dipterous pupa ( Miisca). Middle and hind leg of a Cerambycid be- 
longing to the Acanthocerinoi. Large numbers of ants ; the species found seem to 
be Golobopsis unpressa, Cremastogaster lineolata, Camponotas fallax, Formica 
fusca and Leptothorax curbispinosus. Numerous legs and mouth parts, etc., refer- 
able to one or the other of the species before mentioned make up the bulk ; but ants 
were evidently the principal food. No vegetable food was found; some vegetable 
fibre, and probably obtained from the palmetto, was found, however. 
Red-cockaded Woodpecker (Dryobates borealis)., Adult Male. 
Co7itents. — Fragments of the abdomen only of Brochymeyia species ; also one leg of 
the same. Undigested eggs of perhaps the same insect. Fragments of theabdonfen 
of Cremastogaster lineolatus. Fragments of a myriapod (Julus). 
Red-cockaded Woodpecker (Dryobates borealis), Adult Male. 
Conteyits. — One leg of RrocAi/wena species. One larva of Pyralid. One ant, head 
and abdominal plates, belonging to two different species. Numerous joints of a 
Myriapod (Julus). Parts of legs belonging to ants, hemiptera and coleoptera. The 
stomach was nearly empty and it was evidently a longtime since the bird had made 
a meal. 
Red-cockadp::d Woodpecker (Dryobates borealis), Adult Male. 
Contents. — Numerous fragments of a Cremastogaster, apparently lineolata. One 
coleopterous larval skin, without head or tail ; perhaps of Tenebrio. 
PiLEATED Woodpecker (Ceophloeus jyileatus), Adult Male. 
Conteyits. — Two larvse of Orthosoma brunnea. Five ants (Campoyiotus esiirieyis). 
Remains of other ants. The larva of Orthosoma brunyiea is very destructive to pine. 
PiLEATED Woodpecker (Ceophloeus pileatus). Adult Female.
