Somewhat shining and very closely punctulate, with head red. Head 
large and nearly globose, closely punctate, fulvous and nearly always 
with marks at ocelli and occiput black; not constricted behind the very 
small eyes; vertex very broad and nearly quadrate. Antennae filiform 
and a little longer than the body, fulvous beneath. Thorax narrower than 
head, stout, dull and very closely punctulate above; prothorax often ful- 
vous; pleurae sparsely punctate, with a nitidulous area at metapleural 
suture; metanotum distinctly areated, with petiolar area elongate. Scu- 
tellum punctate and a little convex. Abdomen clavate, shining and black 
with the second segment entirely or partly, and base of third, red; basal 
segment gradually explanate apically, sparsely punctate, with obsolete or 
no discal sulcus; terebra curved. Legs somewhat slender, black with 
front femora and anterior tibiae fulvous; hind tibiae infuscate-testaceous ; 
calcaria elongate. Wings with stigma infuscate-testaceous, tegulae 
nigrescent and radix pale; areolet not small, triangular and sessile; ner- 
vellus intercepted a little above its centre. Length, 64—74 mm. 
This is a rare species in Germany, Sweden and France. Desvignes did 
not understand it and I have seen no indigenous examples. Bridgman 
records it from Britain (Trans. Ent. Soc. 1889, p. 433) on the strength of 
an unlocalised specimen in C. W. Dale’s collection, which the latter tells 
us (E.M.M. 1890, p. 24) was captured by himself, with a second at Glan- 
villes Wootton in Dorset on 30th July, 1888; these are presumably now 
in the Oxford Museum.

Perilissus buccinator, Holmgr. Sv. Ak. Handl. 1855, p. 122, 2. P. (Poly- 
oncus) buccinator, Thoms. O. E. ix. 913, ?. 
A very stout and very dull species with the head quadrate and unusually 
large, even in the present genus. Mouth, underside of antennae, often 
apex of scutellum, abdomen except basally, and the anterior legs only, 
rufescent; hind legs infuscate or nigrescent throughout with only the 
trochanters or in @ also coxae apically testaceous, with calcaria and all 
the tarsal joints at their extreme base whitish. Metanotum short, convex, 
scabriculous and dull with areola strong, broad and nearly oval; costulae 
of wanting; petiolar area basally strong but not occupying more than 
the apical third. Basal segment discally curved, dull, narrow and_ black 
with subcentral spiracles and only sulcate at its base; ¢@ anus deplanate, 
Q anus subcompressed with terebra not exserted. Areolet petiolate, 
obliquely subquadrate and entire, emitting recurrent nervure nearly from 
its centre; nervellus opposite and intercepted hardly above its centre. 
Length, 64—8 mm.
