78 HETEROMEBA. [Anasjrig. 



and with the fourth segment produced in the middle behind and the fifth 

 deeply cleft ; anterior tarsi moderately dilated. 



On flowers, &c. ; local and not uncommon in some districts; London district, rather 

 common, Durenth Wood, Mickleham, Penge, Ripley, Forest Hill, Dulwicli, Cliing- 

 ford, West WifikhamJ Chatham, Sheerness, &c. ; Dover; Hastings ; Portsea ; New 

 Forest ; Glanvilles Wootton ; Bristol ; Swansea ; Hertford j Cambridge ; Norfolk ; 

 Suffolk; Midland districts, generally distributed; Lincoln; Whitby; Manchester; 

 Northumberland and Durham district, rare, but widely distributed ; Scotland, not 

 common, Solway, Tweed, Forth, and probably other districts. 



A. ruficollis, F. Black, thickly clothed with silky greyish 

 pubescence, with the mouth parts, base of antennae, thorax, and the 

 greater part of the legs reddish-testaceous ; the tarsi, apex of tibiae and 

 sometimes part of femora are infuscate ; thorax broader than long, very 

 finely strigose transversely ; elytra subparallel, bluntly rounded at apex, 

 rather more strongly strigose than thorax; the antennas are longer in the 

 male than in the female, and in both sexes are comparatively long ; in 

 the latter the penultimate joints are as Ions as broad, and in the former 

 they are evidently longer than broad ; the head is said to be occasionally 

 rufous, but I have seen no British specimens of this variety. L. 2|-3j 

 mm. 



Male with the third ventral segment of the abdomen strongly and 

 broadly produced and narrowly emarginate at apex, with appendages 

 reaching the fifth segment and curved internally, fourth segment with 

 two smaller appendages ; anterior tarsi scarcely dilated. 



On flowers of white-thorn ; common and generally distributed throughout Eng'and 

 and Wales, but probably less common towards the north, as it appears to be only 

 occasional in Scotland, where it 1 as hitherto occurred solely in the Solway and Forth 

 districts, although it most likely will be found throughout the southern counties ; 

 Ireland, Dublin, Armagh, Belfast, and probably general. 



A. flava, L., v. thoracica, L. (flava, Thorns. ; s.g. Nasipa, Emery). 

 Elongate, yellow, or yellow-testaceous, with the apical portion of the 

 antennae, and the breast and abdomen, blackish or pitchy black ; elytra 

 variable, in our British specimens pitchy black or pitchy yellow brown ; 

 in the type form they are yellow, or yellow with apex broadly or nar- 

 rowly fuscous; the legs also are variable in colour, being usually entirely 

 yellow, but sometimes more or less fuscous, especially the posterior pair ; 

 the antennae are short, thickened towards apex and with the penultimate 

 joints distinctly monilifbrm; the thorax is nearly as long as broad, very 

 finely sculptured, with the posterior angles slightly obtuse ; the elytra 

 are very finely, but distinctly, strigose transversely ; the upper surface is 

 clothed with rather strong silky yellowish pubescence. L. 2|-3j mm. 



Male with the abdomen without appendages, the fifth segment cleft, 

 and the anterior tarsi dilated. 



On flowers, &c. ; local, but somewhat widely distributed ; London district, not 

 uncommon, Ripley (Surrey), Darenth Wood, Claygate; Thames Ditton ; Hastings; 

 New Forest ; Devon ; Knowle, near Birmingham ; Repton ; Northumberland and 

 Durham district, apparently rare ; Scotland, rare, Solway district.
