236 LONGICOUNIA. [Lcjifura. 



the posterior "angles of the thorax produced into a spine ; the larvae are 

 a little narrower behind than in front, but do not call for any particular 

 remark ; of the six JJritish species one or two are doubtfully indigenous. 

 L. rnfa 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. Antennae less distant at base; thorax channelled ; 

 upper surface clothed with very thick greenish pubes- 

 cence L. TIEENS, L. 



II. Antennre rather widely distant at base; thorax not 

 or ob*oletely channelled ; upper surface more or less 



scantily clothed with greyish pubescence. 

 i. Anterior coxul cavities open behind. 



1. Colour entirely black ; length 14r-18 mm. . . . L. SCPTKLLATA, F. 



2. Elytra of mule yellowish or yellow-brown with 

 the'apex broadly, and the exterior margin narrowly, 

 black ; of the female bright red ; length 9-12 



mm L. SANGTTINOLBNTA, L. 



3. Elytra testaceous or yellow-brown, uuicolorous in 



both sexes ; length 6-7 mm L. LIVIDA, F. 



ii. Anterior coxal cavities closed behind; elytra yellow 



with apex black ; length 10-12 mm L. FULVA, De 0. 



Xi. 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, antennae 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. L. 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 (pecimens 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. 



It. scutellata, F. A large and robust species, rather broad, 

 especially in the female, entirely of a deep Hack colour, with the under- 

 side rather thickly clothed with silky greyish pubescence, and the upper- 

 side scantily pubescent ; head veiy 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 

 sen tell um thickly clothed with greyish pubescence ; elytra deeply and 

 coarsely punctured towards base, rather finely towards apjx. L. 14- 

 18 mm. 



Male with the posterior tarsi longer than in female, and the fifth 

 ventral segment deeply emarginate at apex. 



In ol.l stumps of beech, ic. ; rare ; New Forest (in some numbers) ; it has also 

 been recorded from Cubhuni I'ark, Epping Vorest, and llainault Forest.
