236 LONGICORNIA. [ Leptura. 
the posterior angles of the thorax produced into a spine ; the larve are 
a little narrower behind than in front, but do not call for any particular 
remark ; of the six British species: one or two are doubtfully indigenous. 
L. rufa has been comparatively recently introduced, and rests on one 
specimen, so that it requires further confirmation before it can be admitted 
into our lists. 
I. Antenne less distant at base; thorax channelled; 
upper surface clothed with very thick greenish pubes-

L. virens, L. Black, thickly clothed on both upper and under side 
with dense greenish pubescence, which is brighter on the under surface; 
head rather large, antenne ringed with yellow ; thorax convex, strongly 
constricted just before anterior margin, with posterior angles obtuse, very 
closely and rather strongly and rugosely punctured ; elytra broad at base 
and much narrowed to apex, finely, very closely, and rugosely punctured ; 
legs thickly clothed with greenish pubescence ; in the male the fifth 
ventral segment of the abdomen is very slightly excised in the middle 
at apex. LL. 15-18 mm. 
On flowers; very rare and doubtfully indigenous; recorded by Stephens from the 
Forest of Dean and from Scotland; one or two other specimens without locality are 
in our collections. Dr. Sharp does not include the species in his Scotch list, and it 
might perhaps with advantage be omitted or placed with the doubtful species. 
L. scutellata, F. A large and robust species, rather broad, 
especially in the female, entirely of a deep black colour, with the under- 
side rather thickly clothed with silky greyish pubescence, and the upper- 
side scantily pubescent; head very closely punctured ; thorax a little 
longer than broad, convex, very strongly and more or less rugosely 
punctured, base strongly sinuate; posterior angles of thorax and 
scutellum thickly clothed with greyish pubescence; elytra deeply and 
coarsely punctured towards base, rather finely towards apex. LL. 14- 
18 mm. 
Male with the posterior tarsi longer than in female, and the fifth 
ventral segment deeply emarginate at apex. 
In old stumps of beech, &c.; rare ; New Forest (in some numbers) ; it has also 
been recorded from Cobham Park, Epping Forest, and Hainault Forest.
