FAMILY COREIDAE 
COREID BUGS 
This is a large family of relatively large bugs, some members 
of which have the legs fiattened and leaflike. They are similar to 
the lygaeids but differ in having numerous veins in the membrane 
of the hemelytra. 
Leptoglossus corculus (Say) occurs commonly in longleaf and 
slash pine seed orchards in north Florida. First and second instar 
nymphs feed on the needles and first year conelets; older nymphs 
and adults feed on the seeds. Adults are reddish-brown to black, 
have long legs, and average 18 mm. in length. A white zig- 
zag jine crosses the wings, and the hind tibiae are fiattened and 
leafiike. Infested cones usually show no external damage symp- 
toms (188). The related species, L. occidentalis Heidemann, a 
serious pest of Dougias-fir seed in California (424) has been ob- 
served feeding on the needles and green cones of Austrian pine in 
Missouri. ; 
FAMILY RHOPALIDAE 
The boxeider bug, Leptocoris trivittatus (Say), often becomes 
a pest wherever boxeider is grown as a shade tree in the United 
States and Canada. In heavily infested areas, it will feed on ash 
and mapie. Adults (fig. 13) are somewhat fiattenea, brownish-black
