78 HETEROMERA. [ Anaspis. 
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, Darenth Wood, Mickleham, Penge, Ripley, Forest Hill, Dulwich, Ching- 
ford, West Wickham, Chatham, Sheerness, &c.; Dover; Hastings ; Portsea; New 
Forest ; Glanvilles Wootton; Bristol; Swansea; Hertford; 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 antenne, thorax, and the 
greater part of the legs reddish-testaceous ; the tarsi, apex of tibie 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 antenne are longer in the 
male than in the female, and in both sexes are comparatively long ; in 
the latter the penultimate joints are as long 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. 23-3} 
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 las hitherto occurred solely in the Solway and Forth 
districts, although it most likely will be found throughout the southern counties ; 
Treland, Dublin, Armagh, Belfast, and probably general. 
A. flava, L., v. thoracica, L. (flava, Thoms.; s.g. Nasipa, Emery). 
Elongate, yellow, or yellow-testaceous, with the apical portion of the 
antenne, 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 antenne are short, thickened towards apex and with the penultimate 
joints distinctly moniliform; 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. 24-3} mm. 
Male with the abdomen without appendages, the fifth segment cleft, 
and the anterior tarsi dilated. 
On flowers, &e.; 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.
