No Illinois species; Clivinema _ villosa 
Reuter occurs in Montana, Oklahoma, 
Texas. 
Bothynotus Fieber 
Bothynotus modestus (Wirtner) 
Neobothynotus modestus Wirtner (1917, p. 
4), 
This species is distinguished from the 
other known American species by its large 
size and longer antennae; also, the length

of the second antennal segment is much 
greater than the width of the head. 
Mare.—Fig. 103. Length 5.10, width 
2.40. Head width 0.99, vertex 0.56. Ros- 
trum reaching to bases of hind coxae, length 
1.60. Antennae, first segment, length 0.49,

fusco-brownish, strongly pubescent; second 
segment, 1.50, black, cylindrical, equal in 
thickness to first segment, thickly clothed 
with suberect pubescence; third, 0.69, slen- 
der, pale to dusky, clothed with long pubes- 
cence; fourth, 0.35, slender, fuscous. Pro- 
notum, length 1.30, width at base 1.90; disk 
convex, coarsely and _ closely punctate, 
clothed with long fuscous pubescence. Scu- 
tellum strongly convex, impunctate, pubes- 
cent. Hemelytra with emboliar margins 
subparallel, with sharp edge, clavus and co- 
rium strongly, transversely rugulose; mem- 
brane and veins uniformly dark fuscous, 
thickly clothed with erect fuscous pubes- 
cence. Body black, distinctly shining, head 
red, tylus black, legs very dark brown, 
tibiae somewhat paler and translucent. 
FEMALE.—Length 4.80, width 2.60; em- 
boliar margins distinctly arcuate. Head 
width 1.01, vertex 0.65. Antennae, first 
segment, length 0.51; second, 1.20, more 
slender than first segment, black, paler on 
basal half, clothed with long pubescence; 
third, 0.73; fourth, 0.56. More robust than 
male, but similar in color and pubescence. 
Known DistripuTion.—Described from 
Pennsylvania, where it was found on pine 
trees. Single specimens are now known 
from Illinois, Kansas, Maryland, Ohio. 
Apparently this is a rare but widely distrib- 
uted species.
