This species is allied to Jaetus Van Duzee, 
but is darker in coloration; it differs in the 
shorter and more gradually thickened sec- 
ond antennal segment; also in the narrower 
head. 
Mavte.—Length 3.70, width 1.30. Head 
width 0.91, vertex 0.49. Rostrum, length 
1.06, attaining middle of intermediate coxae. 
Antennae, first segment, length 0.28, brown- 
ish; second, 1.11, gradually thickened from 
middle toward apex (0.10 thick), length not 
equal to distance between tip of tylus and 
base of pronotum, brown, apical half black; 
third, length 0.44, pale, infuscated apically; 
fourth, length 0.42, infuscated. Pronotum, 
length 0.71, width at base 1.11; very dark 
brown, sides more gradually sulcate than in 
laetus. General color very dark brown, al- 
most black; hemelytra nearly as in Jaetus, 
but darker; membrane blackish on _ basal 
half, pale fuscous on apical half and on area 
bordering cuneus; legs fusco-brownish, ven-

present on either side of third to fifth ster- 
nites. 
FEMALE.—Length 3.50, width 1.12. Very 
similar to male in structure and coloration.

fourth, 0.32, fuscous. Pronotum, length 
0.64, width at base 1.05; from tip of tylus to 
basal margin of pronotal disk, 1.14. General 
color dark brown; hemelytra lighter brown; 
corium behind posterior silvery band and 
exterior to radial vein dark brown and pol- 
ished; membrane pale fuscous, a brown 
cloud covering larger areole and area just 
behind. Dorsum clothed with short, soft 
pubescence except for bands; posterior sil- 
very band slightly irregular, widely discon- 
nected at claval suture, that portion on 
clavus set well forward but transverse in 
position; basal band thick, just opposite tip 
of scutellum, extending from costal edge to 
claval suture; sides of venter with arcuate 
band of dense, silvery pubescence extending 
from second to sixth sternites; paracuneus

FEMALE.—Length 3.70, width 1.30. More 
robust than male, but very similar in color
