NO. 3651 ARADIDAE V——KORMILEV 11 
terior process stout, with large, expanded, and rounded anteriorly 
genae, contiguous in front of clypeus and produced slightly beyond 
tip of antennal segment I. Antenniferous tubercles narrow, acute, 
diverging, reaching to the middle of antennal segment I. Eyes semi- 
globose, protruding. Postocular tubercles small, acute, produced as 
far as eyes, or slightly beyond. Infraocular carinae high, thin, finely 
granulate. Vertex with M-shaped group of granulations. Antennae 
slender; relative length of antennal segments I to IV: o&, 9:6:12:7.5; 
9, 9:6.5:12:8.5. Labium short, reaching to hind border of labial 
eroove, latter closed posteriorly. 
Pronotum half as long as maximum width (07, 25:51; 9, 25:54); 
forelobe narrower than hind lobe (o%, 43:51; 9, 44:54). Collar thin, 
slightly sinuate in front. Anterolateral angles expanded, rounded, 
slightly reflexed, crenulate, produced forward as far as collar. Lateral 
notch distinct, forming an obtuse angle. Lateral borders of hind 
lobe subparallel, converging anteriorly, crenulate; hind border feebly 
sinuate. Foredise with four (2 + 2) high, granulate ridges; hind disc 
more roughly granulate. 
Scutellum shorter than basal width (co, 20:25; 9, 25:27). Lateral 
borders carinate, sinuate on apical half; apex widely rounded. Median 
ridge cross shaped, roughly granulate. 
Hemelytra reaching to hind border of tergum VI in both sexes. 
Corium with convex basolateral borders; apical border convex, 
rounded; apical angle also rounded. Veins of corium densely granulate. 
Abdomen ovate in both sexes; longer than maximum width across 
segment IV (o, 74:62.5; 9, 80:65). Connexivum wide, slightly 
reflexed exteriorly, exterior borders of segments straight, crenulate; 
PE angles not, or barely protruding; PE VII angularly rounded in 
both sexes. Paratergites (co) small, clavate, reaching slightly over 
two-thirds of hypopygium; latter cordate, shorter than wide (15:20), 
with a median ovate ridge not reaching tip of hypopygium. Parater- 
gites (2) large, rounded, reaching middle of segment IX, latter incised 
posteriorly. All spiracles ventral, not visible from above. 
Cotor.—Piceous with rusty brown granulations; genae, antennae, 
tips of antenniferous tubercles, lateral borders of forelobe of pro- 
notum, PE angles, and hind borders of connexiva, coxae, trochanters, 
and tarsi, yellow brown to rusty brown. Exterior borders of connexiva 
on forehalf, black. Round callous spots on connexiva and venter 
reddish brown. 
MeAsuREMENTS.—Total length: o, 5.80; 9, 6.12 mm; width of 
pronotum: o’, 2.04; 9, 2.16 mm; width of abdomen: 0, 2.50; 2, 2.60 
mm.
