Red-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 larvae; judging 
from their last joints they belong to the genus Tenebrio, the larvae 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 different 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 larvae 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 granulatus , Say. Numorous 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 ( Musca ). Middle and hind leg of a Cerambycid be¬ 
longing to the Acanthocerinai. Large numbers of ants ; the species found seem to 
be Colobopsis impressa, Or emastogaster lineolata, Camponotus 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. 
Contents. —Fragments of the abdomen only of Brochymena species ; also one leg of 
I the same. Undigested eggs of perhaps the same insect. Fragments of the abdomen 
of Cr emastog aster lineolatus. Fragments of a myriapod (Julus). 
Red-cockaded Woodpecker (Dryobates borealis), Adult Male. 
Contents. —One leg of Brochymena 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-cockaded Woodpecker (Dryobates borealis ), Adult Male. 
Contents. —Numerous fragments of a Cr emastog aster, apparently lineolata. One 
coleopterous larval skin, without head or tail ; perhaps of Tenebrio. 
Pileated Woodpecker (Ceophloeus pileatus), Adult Male. 
Contents. —Two larvae of Orthosoma brunnea. Five ants ( Camponotus esuriens). 
Remains of other ants. The larva of Orthosoma brunnea is very destructive to pine. 
Pileated Woodpecker (Ceophloeus pileatus), Adult Female. 
Contents. _Two larvae of Orthosoma brunnea. Numerous Cremastogaster line¬ 
olata. Numerous Camponotus esuriens and their cocoons. One larva ot Xylo- 
trechus spec. 
Pileated Woodpecker (Ceophloeus pileatus), Adult Male. 
Contents. —One larva of Orthosoma brunnea. Five ants ( Camponotus esuriens), 
\ and fragments of the same. 
Pileated Woodpecker ( Ceophloeus pileatus), Adult Male. 
Contents. _Numerous fragments of Camponotus esuriens. Fragments of a Ceram¬ 
bycid larva ( Xylotrechus ?).
