Description
Length
4.9–6.5 mm
, mean (24) = 5.46. Head usually with more or less distinct frontal pit or irregular smooth area (often with both); rostrum more slender in male: × 4.5–5.1 as long as broad, mean (6) = 4.78, than in female: × 4.2–4.8 as long as broad, mean (8) = 4.49; punctures on upper surface fairly regular, interspaces sometimes uniting to form irregular carinulae but often without any trace of a median carina or apical carinula; sides above scrobes usually widening somewhat abruptly but sometimes evenly, as in
P. armillatus
.
Antennae with lengths of funicle segments
1–3 in
ratio 10: (6.0–7.1): (3.3–4.8), mean (15) = 10: 6.6: 4.1; segment 2 × 1.5–1.9 as long as 3, mean (15) = 1.6; segment 1 × 2.1–3.0 as long as 3, mean (15) = 2.46; segment 7 weakly transverse, × 0.8–0.9 as long as broad, mean (12) = 0.87.
Prothorax with pronotal punctures fairly regular, interspaces forming a regular reticulum on disc; smooth median line vestigial.
Legs with fore tibiae straight or weakly sinuous, middle tibiae straight, hind tibiae evenly curving dorsad (as in
P. picipes
).
Vestiture rather coarse, white setae forming a variegated pattern on elytra and condensed at top of declivity to form white flecks in interstriae (2), 3 and (4) which together can form a short interrupted transverse band (
Fig. 8
); tibiae as in
P.
p. picipes
.
Terminalia. Male sternite 8 with very slender column and slender curved bladelike processes (
Figs 92–95
); female sternite 8 with pigmented areas more or less fused, setae small (<
0.03 mm
)(
Figs 39, 40
); spermatheca with glandlobe conical at base, weakly expanded at apex and not, or only weakly, deflexed (
Figs 65–67
).
Type material
LECTOTYPE
of
Procas biguttatus
Faust
, here designated, female, with small square of goldsurfaced paper (now oxidised to brown); ‘Wladiwast./ Christoph.’ (Faust MS); ‘Coll. J. Faust / Ankauf 1900’ (printed, on yellow card); ‘Type’ (printed on red card); ‘biguttatus’ (MS, on yellow card) and ‘
LECTOTYPE
Procas biguttatus Faust
det. R.T.
Thompson 2003
’ in SMT. The specimen is carded and in good condition (two tarsi are incomplete); it has white spots on both interstriae 2 and 3, so fits the description better than the other
syntypes
.
PARALECTOTYPES
:
3 females
with same labels as
lectotype
; one is mounted below the
lectotype
, on the same pin, the other two have no original determination label. Faust states that he had
four specimens
but adds ‘und vom
Amur
.’
HOLOTYPE
of
Notaris okunii
Kôno
, male, with ‘Sapporo / T. Okuni’ (printed) and ‘late August [in Japanese]/ 1912’ (
MS
, under label); ‘
Notaris
/ okunii / Kôno’ (
MS
) and ‘Type’ (printed) on pale crimson label; ‘
Procas
/ biguttatus / Faust’ (
MS
) and ‘det. H. Kôno’ (printed) on white label in HUM. The specimen is
6.3 mm
in length and lacks the right hind leg which was apparently pushed off by the pin, which has also displaced the venter. The tibiae, femora and parts of the elytra are dark redbrown in colour, indicating that the specimen is somewhat teneral. The eighth tergite is exposed and shows that the specimen is male, not female, as stated by Kôno.

Comments
All the specimens examined have at least one white spot at the top of the elytral declivity but none has a ‘white scutellum.’ The specimen figured by
Caldara & O’Brien 1995
(‘
Procas
sp.
’) appears to be
P. armillatus
.
