The only species I can find which may be compared with this one 

 is A. niqripes, Brisout, which also has the ventral appendages in the 

 male strongly divergent and convex, but in this species, as its name 

 implies, the legs are entirely (or almost entirely) black, the thorax is 

 shorter, and the appendages narrower. 



A. pulicaria, Costa (forcipata, Muls.). 

 Smaller than any of the other black species ; in general appearance resembling 

 a small A. frontalis, from which it may be known by its lesser eize and the characters 

 of the male, in which sex the appendages of the third segment are rather stout, 

 straight and parallel, and not curved inwards towards one another at apex ; the 

 male characters and the darker legs (the anterior pair alone being mostly yellow and 

 the rest black) will distinguish it from A. Qariieysi, and the finer sculpture and less 

 moniliform antennae will separate it from A. rufilabris. Length, 1\ — 2f mm. 



On flowers, &c. ; locally common — Shirley, Mickleham, Esher, 

 Darenth Wood, Chatham, Chingford, Dulwich, West Wickham, Cow- 

 ley, &c. ; Dover ; Hastings ; Brockenhurst ; Glanvilles Wootton ; 

 South Wales ; Needwood, near Burton-on-Trent ; Bepton ; Northum- 

 berland district, Wallington. The species has probably been overlooked 

 in many localities, and most likely has been confounded with small 

 specimens of the allied species. 



A. rufilabris, G-yll. (atra, P., s. g. Nasipa, Emery). 



Elongate, subfusiform, black or pitchy-black, clothed with brownish or greyish 

 silky pubescence, with the labrum, base of antennas and tibial spurs, testaceous, and 

 the greater part of the anterior legs, and the posterior pairs in part, rufescent or 

 pitchy ; antennas short, moniliform, more strongly so in male than in female ; thorax 

 about one-third broader than long, evidently strigose, especially at sides, with the 

 posterior angles somewhat acute ; elytra distinctly and comparatively strongly strigose 

 transversely ; in some specimens the legs are black or nearly black, and in others the 

 greater part of the head and sides of thorax are pitchy, or appear to be sometimes 

 even reddish. Length, 2£ — 3j mm. 



Male with the anterior tarsi with the first joint transverse, slightly dilated, and 

 the second and third joints strongly dilated, and with the third ventral segment of 

 the abdomen furnished in middle with two nearly straight appendages, approximate 

 at base, and slightly divergent behind, not reaching the apex of abdomen. 



On flowers, &c. ; occasionally by beating dead twigs ; local, but 

 not uncommon in many districts, although, apparently, often overlooked; 

 Darenth Wood, Leith Hill, Mickleham, Cowley ; Portsea ; New Porest ; 

 Glanvilles Wootton, Dorset ; Sutton Park and Solihull, near Birming- 

 ham ; Repton, Bretby Wood (on wild cherry blossom) ; Dunham 

 Park, Manchester ; Northumberland and Durham district, Wallington, 

 and several other localities ; Scotland (common in flowers), Solway, Tay, 

 Dee, Moray, and probably other districts ; it is probably not uncommon 

 in Ireland.
