Olibrus.] CLAVICORNIA. 151 



tured ; legs and under-side reddish-yellow; male with-the second joint 

 of the anterior tarsi slightly dilated. L. 2$-3 mm. 



By sweeping, and sometimes by beating ; local, but rather common in some places ; 

 London district, generally distributed aud not uncommon ; Hastings ; Eastbourne ; 

 Isle of Wight ; Bournemouth ; Glauvilles Wootton ; Exeter ; Swansea ; Huntingdon- 

 shire ; Sandringham, Norfolk ; Northumberland district, rare, Hetton Hall, near 

 Belford ; Scotland, very rare, Forth district; Ireland, near Dublin; the species 

 appears to be very rare in the Midland counties, if it occurs at all : I have never met 

 with it, and Mr. Blatch does not mention it in his list. 



O. sen e us, F. (multistriatiis, Zett.). Bather long-oval, convex, nar- 

 rowed behind, black with a greenish-metallic reflection, very shining ; 

 head exceedingly finely punctured ; antennae black with the basal joints 

 reddish (a character that will distingu : sh it from all the other species 

 except 0. millefoUi, which sometimes has the club dark, but i^ a very 

 much smaller and quite black insect) ; thorax sparingly and very finely, 

 almost invisibly, punctured, posterior margin sinuate on each side near 

 scutellum ; elytra with two distinct striae near suture, and with the other 

 striae very fine but moderately distinct for a member of the genus, inter- 

 stices very finely punctured ; under-side pitchy-brown with thin and fine 

 greyish pubescence ; legs variable in colour, as a rule pitchy, but occa- 

 sionally pitchy-reddish or even yellowish ; the apex of the elytra is 

 sometimes obscurely pitchy. L. 2-2j mm. 



By sweeping, in flowers, &c. ; common and generally distributed in the London 

 district and the south, and not uncommon, although somewhat local, in the Midlands; 

 rarer further north ; Northumberland district, local and rare ; Scotland, Tweed 

 district. Murray records the species as generally distributed, but Dr. Sharp has 

 only met with it in the Cheviot district, so that Murray is probably in error, espe- 

 cially if we consider the distribution of the insect in England. Ireland, near Dublin 

 aud Waterford. It appears to be attached to Matricaria, chamondlla. 



O. liquidus, Er. Oblong-ovate, pitchy-black or browish, more or 

 less gradually lighter towards apex of elytra ; head very finely punctured, 

 antennae and palpi yellow or reddish-yellow ; thorax slightly rounded at 

 sides, upper surface very finely punctured, posterior angles obtuse ; elytra 

 with the two striae near suture distinct, and with the other striae mode- 

 rately distinct but very fine ; interstices finely punctured ; legs and 

 under-side reddish-yellow ; male with the second joint of the anterior 

 tarsi very slightly enlarged. L. 2-2^ mm. 



By sweeping, in flowers, &c. ; local ; London district, common and generally dis- 

 tributed ; Harwich; Dover; New Forest; Bournemouth; Weymouth ; Weston- 

 snper-Mare ; Tenby (common in flowers of Hieraeium on the cliffs towards 

 Lydstep) ; Barmouth ; not recorded from the Midland districts, the north of England 

 or Scotland. 



0. bicolor has until recently been included in the British list, but has 

 been dropped on the ground that the examples so named are merely 

 large specimens of 0. liquidus ; I have, however, a specimen from Dr. 

 Power's collection which in some points agrees very well with the
