always showing through this infuscation; 
legs fusco-brownish to blackish; femora 
exhibiting one or two rows of darker spots 
both above and below. Clothed with short, 
pale pubescence; a few stiff, black hairs on 
scutellum. Genital claspers very distinctive 
for species, fig. 121. 
FEMALE.—Length 5.70, width 1.80; usu- 
ally colored very similarly to male, but 
sometimes with embolium and outer edge of 
cuneus pale or white as in heidemanni 
Knight. 
Foop PLants.—Goldenrod (Solidago ru- 
gosa) and several other plants. Illinois 
specimens were collected on _ spiderwort 
(Tradescantia sp.), hazelnut (Corylus sp.), 
willow (Salix sp.), ash (Fraxinus sp.) and 
red birch (Betula nigra). 
Known Distripution.—A common and 
widely distributed species east of the Rocky 
Mountains.

Lopidea staphyleae Knight 
Lopidea staphyleae Knight (1917d, p. 460). 
Matre.—Length 6.50, width 2.05. An- 
tennae, first segment, length 0.71, thickness 
0.15; second, 2.48, thickness 0.10, tapering 
to become slightly smaller on apical half; 
third, 1.82, slender and almost linear; fourth, 
0.52. General color mostly orange yellow, 
with calli, narrow area at base of pronotum, 
scutellum, apical two-thirds of clavus, inner 
half of corium, and membrane, fuscous; 
antennae, tylus, two bars on front, base of 
head, rostrum, and legs, black; fuscous 
shading on dorsum much paler than in 
robiniae (Uhler) ; genital claspers, fig. 121, 
distinctive for species. 
FEMALE.—Length 6.80, width 2.20. Simi- 
lar to male in structure and coloration, but 
usually slightly larger; sometimes very simi- 
lar in size and coloration to female of con- 
fluenta (Say), but length of first antennal 
segment in confluenta is shorter than width 
of vertex, while in staphyleae its length is 
as great as, or slightly greater than, width 
Vol'22,-Arivg 
of vertex. Head width 1.29, vertex 0.78. 
Antennae, length of first segment, 0.81; sec- 
ond, 2.64. 
Specimens in which the orange yellow 
areas become red constitute var. sanguinea 
Knight (1917d, p. 461), taken in Illinois 
chiefly in northern localities. 
Foop PLANT.— American bladder nut 
(Staphylea trifolia) ; a single Illinois speci- 
men was collected on willow (Salix sp.), 
but that tree was probably not its host. 
Known DiIstrRiBUTION.—Connecticut, 
Illinois, Iowa, Kansas, Maryland, Massa- 
chusetts, Minnesota, New York, Oklahoma, 
South Carolina, Virginia. 
Illinois Records.—Thirty-two males and 
47 females, taken June 2 to Aug. 22, are 
from Apple River Canyon State Park, 
Bloomington, Decatur, Dolson, Glendon 
Park, Grafton, Grand ‘Tower, Hardin, 
Havana, Homer Park, Kampsville, Karnak, 
Monticello, Parker, Seymour, Urbana, Wil- 
low Springs. 
Lopidea amorphae Knight 
Lopidea amorphae Knight (1923c, p. 65). 
Matre.—Length 5.90, width 2.00. Head 
width 1.10, vertex 0.34. Antennae, length 
of first segment, 0.60; second, 2.09, thickness 
0.11, tapering to become more slender on 
apical half; third, length 1.20; fourth, length 
0.40. Pronotum, width at base 1.84. Hem- 
elytra with red areas bearing fine, yellowish 
pubescence, while in reuteri Knight these 
areas bear black pubescence. Smaller than 
reuteri and more yellowish in color, majority 
of specimens more yellowish than red. Geni- 
tal claspers, fig. 121, indicate a close rela- 
tionship with reuteri, but in the large series 
examined distal portion of right clasper 
shows constant differences. 
FEMALE.—Length 6.30, width 2.30; very 
similar to male in form, pubescence and 
coloration. 
Foop PLant.—False indigo (Amorpha 
fruticosa) ; a single specimen was also taken 
in Illinois on red clover (Trifolium pra- 
tense). 
Known DistrisuTtion. — Illinois, Iowa, 
Kansas, Minnesota, Nebraska, South Da- 
kota, but may be expected from other states 
where the host plant grows in abundance.
