A black species, with pale capital and thoracic markings ; legs red, 
hind tibiae whitish with their apex broadly and extreme base black; 6 
with third segment often obscurely red at its base, and the mesosternum 
and hind coxae black. Length, 4—5 mm. 
Extremely like the last species and probably no more than a small form 
thereof, having less extensive pale markings which will serve to differ- 
entiate it; from H. longiventris it may be known by its less elongate 
abdomen, subtransverse second segment, paler stigma, more broadly black 
hind tibiae and the immaculate male mesosternum. 
I possess a @ of this species with a distinct areolet in the left wing, 
but no trace of one in the right. The type of B. ¢horacicus is not in the 
British Museum, and the description might, with almost equal propriety 
be supposed to refer to HY. abdominator, were the areolet less definitely 
instanced. 
It is not quite of such common occurrence as the last species, though 
probably equally widely distributed both here and abroad; it appears 
much more nearly confined to woods, being usually beaten from the 
branches of trees and shrubs there ; and all my specimens were captured 
in June, though I possess several taken also in September, but with no 
intermediate dates. Eaton, near Norwich (Bridgman) ; Felden in Herts 
(Piffard) ; Shere in Surrey (Capron); Bury St. Edmunds (Tuck) ; Black- 
heath (Beaumont) ; Wimbledon (W. Saunders); Bugbrook in Northants 
(Marshall); and Delamere Forest (Tomlin). I have found it, always 
singly, at Norton Wood and Calbourne, Isle of Wight; and in Suffolk at 
Brandon, Barhum Oak Wood, Staverton Thicks and in Tuddenham Fen. 
18. incisus, Thoms. 
Homoporus incisus, Thoms. O. E. xiv. 1511, ?; Morl. Trans. Ent. Soc. 1905, 
p.424, ¢. 
A black species with apex of scutellum, mouth and the centrally 
strongly incised clypeus, stramineous; legs red with the hind tarsi and 
tibiae black, the latter before their base dull testaceous. 4 epistoma, 
clypeus and mouth excepting apices of mandibles, stramineous ; orbits 
and cheeks immaculate; a broad subhamate line before and a callosity 
beneath the front wings, with the basal margin of the mesopleurae, 
stramineous ; apices of scutellum and postscutellum, with the sides of the 
former somewhat broadly, flavous; legs pale red with all the coxae and 
trochanters, and the hind tibiae except at their extreme base and apex, 
whitish ; abdomen immaculate, subparallel-sided and broadest behind 
the centre. Length, 4—54 mm. 
Extremely closely allied to the preceding and differing almost entirely 
in the conformation of the clypeus, which is laterally, though not 
apically, reflexed and much more deeply emarginate in the centre of its 
apex; Thomson gives the length of the Swedish female as 34 lines or 
fully seven millimetres, but the British examples appear to run much 
smaller,
