Polyblastus Westringi, Holmgr. Sv. Ak. Handl. 1855, p. 210, ¢. 
A strongly nitidulous, black species with the mouth, clypeus, broad 
lateral Q facial marks, tegulae, segmental apices and part of legs, 
flavidous. Clypeus convex and slightly impressed before its subtruncate 
apex. Antennae a little shorter than body and infuscate, becoming 
rufescent basally beneath. Metathorax semiglobose, with the areae 
obsolete and incomplete. Scutellum not pyramidal. First segment nar- 
rowed towards its base, somewhat smooth, margined, and subsulcate 
beyond the centre, with its carinae indeterminate ; following segments 
transverse, shining and pale-margined; terebra exserted, black and 
pilose. Legs normal and pale red with apices of hind femora, tarsi and 
tibiae black, the last concolorous before their base and centrally, like the 
anterior trochanters, flavous; hind coxae of Q sometimes partly infus- 
cate. Areolet usually wanting; stigma black; radial nervure apically 
subreflexed ; nervellus intercepted below its centre. Length, 5 mm. ¢ 9. 
All the examples I have seen lack areolet, which is not indicated by its 
author and will at once distinguish this species from P. pimguis, than 
which it is more slender. The undescribed g is commoner than the ? 
with us; it differs in nothing but the paler hind coxae, antennal base and 
immaculate flavous face. 
Boheman and Holmgren found this species in pine woods in Sweden 
during the middle of July, and Gaulle says it extends to France. Though 
not hitherto recorded from Britain, it is one of our commonest species, 
ranging at least from the Isle of Wight to Yorkshire; Bishops Teignton 
(Marshall coll.), Plym Bridge in Devon, 14th July (Bignell), South Cove 
near Hull in June, 1907 (Roebuck); Guestling near Hastings (Bloom- 
field), Box Hill, Surrey, in 1874 (Champion), a full series from Shere 
(Capron coll.); I have captured it in Marvell Copse, near Newport in Isle 
of Wight, in June, swept it in Tuddenham Fen in Suffolk early in July, 
and beaten it from hazel bushes at Ringstead in Norfolk in August ; 
Grimshaw took it at Westport, Co. Mayo, in August, 1911.

Shining and black with the thorax broadly red and the mouth, clypeus, 
lateral facial marks, tegulae, segmental apices and venter pale stramineous. 
Clypeus convex and subimpressed before its rounded apex. Antennae a 
little shorter than body, pale ferrugineous with the scape black, stramin- 
eous beneath. Mesothorax entirely bright red; metathorax short and 
black, with the areola very distinct and costulae obsolete; petiolar area 
subperpendicular. Scutellum black and convex, but not pyramidal. Basal 
segment subconvex, rugose, with the carinae stout and extending nearly 
to apex; second and base of third also rugose, with the remainder nitidu- 
lous; terebra exserted, black and pilose. Legs somewhat slender and 
red with anterior trochanters stramineous, hind tarsi and apices of their 
white-pilose tibiae infuscate; apical joint of front tarsi somewhat dilated;
