RHYSCHOPnORA. 



317 



pubescence ashy white, mixed with yellowish hairs, the white hairs 

 forming a central line on the thorax and covering the scutellum ; there 

 is a white transverse band behind middle, and other obsolete white 

 markings ; the band is almost straight, wider towards sides and narrowed 

 and interrupted at suture ; rostrum elongate, cylindrical, almost straight, 

 and rather dull, at all events behind; thorax transverse, slightly rounded 

 behind ; scutellum oblong ; elytra flat at base, convex behind, with a 

 well-marked elevation at the base of the third interstice ; punctured 

 striae moderately strong, interstices flat, rather shining, comparatively 

 smooth ; anterior femora armed with a long sharp triangular tooth ; 

 anterior tibiae very strongly sinuate on their inner margin, the margin 

 being almost angled in the centre. L. 2-2f mm. 



By beating hedges (I believe on Cratcegus) ; Repton, Burton-on-Trent (Robins 

 Wood and near osier beds at Bull's in the meadows) and Bircham Newton, Norfolk ; 

 1 bad the species separated in my collection for some time, and sent a specimen to 

 M. Bedel, who returned it as A. RosintB ; it certainly looks very distinct; I believe 

 tliat it is by no means uncommon ; M. des Gozis says that it appears to be not rare 

 in France. 



A. pedicularius, L. Very like the preceding but on the average 

 slightly smaller ; it is, however, very variable both as regards colour 

 and size, the former varying from bright red, almost scarlet, to deep 

 ferruginous or pitchy red ; it may be distinguished from A. ulmi by its 

 broader scutellum, less prominent eyes, shorter and stouter rostrum, 

 more broadly distant intermediate coxse and shorter thorax, and especi- 

 ally by the much straighter and scarcely sinuate anterior tibiae and the 

 less strongly marked teeth of the anterior femora ; the underside, more- 

 over, is more thickly clothed with whitish pubescence, and the antenna? 

 are inserted near to apex of rostrum ; in fresh specimens the elytra pre- 

 sent the appearance of having two white fasciae and two denuded bands, 

 the anterior fascia being much more scantily pubescent than the pos- 

 terior ; this is also the case more or less in the preceding species. L. 

 3-3f mm. 



On the flowers of white thorn and also on other shrubs and trees, but mostly 

 attached to the former ; generally distributed and common throughout the kingdom. 



A. Chevrolati, Desb. Closely allied to A. pedicularius, which it 

 resembles in general colour and size, but shorter and more convex, with 

 the thorax and elytra appearing separately convex if viewed sideways ; 

 it may, moreover, be easily known by the shape of the thorax, which is 

 more transverse than in the preceding species, slightly narrowed at the 

 base and very strongly so at the apex, and with the sides conspicuously 

 rounded before the middle ; the interstices, moreover, of the elytra are 

 smaller, there is no trace of a tubercle at the base of the third interstice, 

 and the anterior whitish fascia is somewhat curved towards the scutel- 

 lum ; the colour, as in the two preceding species, is variable L. 3-3^
