transversely striate-rugose (fig. 22). Occiput
mostly glabrous except foveate laterally.
Lateral pronotal carina distinct, except
dorsomedially (fig. 25). Lateral surface of
pronotum foveate-reticulate. Dorsal area of
pronotum behind pronotal crest glabrous
and complete to end of dorsal posterior
margin of pronotum. Mesoscutum foveatereticulate
with foveae more or less set in rows
between transverse costae. Mesoscutellum
foveate-reticulate, sloping posteriorly and,
viewed from above, rounded posteriorly
(fig. 26). Mesopleural triangle distinctly depressed
and pubescent. Upper mesopleuron
anteriorly punctate-rugose, posteriorly glabrous;
speculum with several setigerous
punctures. Longitudinal mesopleural impression
percurrent with unevenly distributed
transverse costae. Lower mesopleuron glabrous
with setigerous punctures along lower
margin. Metanotal-propodeal complex foveate-rugose
with dense pubescence (fig. 25).
Lateral propodeal carina percurrent, medially
somewhat curved lareally. Median propodeal
area with one or two irregular longitudinal
carinae (fig. 26).
Abdominal petiole slightly shorter than
wide, longitudinally carinate. Relative length
of T3–8: 2:1:1:3.2:1.3:0.9. T4–8 densely finely
punctate. T6–8 also sparsely, coarsely punctate
with hairs (fig. 27). All legs densely
punctate with pubescence. Metatibia apically
with four slender, pointed teeth (figs. 28, 29).
1mt/2–5mt 5 0.6.
MALE: Unknown.
The species is most similar to species of the
scaber group, but can be easily separated
from the latter by the following characters.
Speculum setigerous; median frontal carina
branched posteriorly, delimiting a small triangular,
glabrous area beneath anterior
ocellus; eyes protruding laterally beyond
gena; mesoscutum distinctly convex in lateral
view; wings smoky.

BIOLOGY:
All specimens were collected
in Malaise traps. According to Dr. D. Smith
(personal commun.), the site in Essex Co.,
Virginia, was about 120 acres of woodland
and open grassy areas. The woods were
dominated by pines, mostly Pinus taeda,
Quercus spp., Hicoria spp., Liriodendron
tulipifera, and Liquidambar styraciflua. Part
of the adjacent property was a tree plantation
that had been cut about 15 years earlier and
contained considerable underbrush and
about 10–15-year-old loblolly pines. Traps
were placed at woods edges, along streams,
and within woods and the tree plantation.
The site in Clarke Co. was an experimental
station with about 700 acres and consisted of
woodlands, open fields, and ponds surrounded
by willows. This site was much more
diverse in vegetation than the other site. The
woodlands (one about a 110-year-old 70-acre
woodlot) were dominated by Quercus spp.,
Hicoria spp., and Ulmus spp., with a few
scattered pines. Traps were placed in many
disturbed areas, forest edges, within woods,
and around ponds and willows. The 17
specimens of the type series consisted of 7
from the Essex site collected in 3 years and 10
from the Clarke site collected in 2 years.
Apparently the species is more abundant in
the Clarke site that also had a more deciduous
component in the vegetation. Nonetheless, no
direct host association can be established.
ETYMOLOGY: Name after type locality.
SCABER GROUP
figures 30–37
The group is distributed predominantly in
the far-eastern Palearctic with one exception
from the southwestern Yunnan of China.
DIAGNOSTIC CHARACTERS: Body size
relatively small. Antenna filiform. Female
antenna has 13 segments with F1 distinctly
shorter than F2. Placodes present on all
flagellomeres, short, and not as long as the
