HAPXiOCNEMUS, Stephens. 



This genus contains about seventy species, which are entirely, or 

 almost entirely confined to Europe, the circura-Moditerranean region, and 

 the Atlantic islands ; they are characterized by having the tarsal claws 

 furnished with a free membrane, which is appendiculate and as long as 

 the claws ; the form is comparatively short and broad, and the upper 

 surface is coarsely punctured and clothed with long upright pilose pubes- 

 cence; the larvae live in decaying wood, and the perfect insects may be 

 found in old trees, especially in winter ; in summer, however, they may 

 be taken on flowers, &c. ; our two species are both rare; they are closely 

 allied, and by some authors have been considered as merely varieties of 

 one species. 



I. Upper snrfuce bronze or bronze-blnck ; punctuation of 



elytra less coarse H. IMPRESSUS, Marsh. 



II. Upper surface greenish-bronze or bluish ; punctuation 



of elytra coarser H. NIGRICOBNIS, Fab. 



H. impressus, Marsh, (pini, Redt.). Comparatively short and 

 broad, oblong, convex, clothed with very long brownish pilose pubes- 

 cence, of a bronze or bronze-black colour ; head much narrower than 

 thorax, rather sparingly punctured, antennae brownish, with second joint 

 lighter, a little longer and more strongly serrate in male than in female ; 

 thorax broader than long, with sides rounded, and narrowed towards 

 front, broadest behind middle, not very closely and rather strongly 

 punctured, but much less strongly than elytra; elytra subparallel, very 

 slightly widened behind middle, very coarsely and strongly punctured, 

 with uneven and rather convex shining interstices ; legs reddish-yellow, 

 with the femora brownish, and the tibiae sometimes darker, and the tarsi 

 often fuscous on their upper side. L. 4 mm. 



Under bark of elm, oak, pear, &c. ; occasionally on flowers or foliage in summer; 

 rare ; Forest Hill, Surrey ; Copenhagen Fields (formerly) ; Highgate ; Sheerness ; 

 New Forest ; Glanvilles Wbotton ; Sutton Pitrk, Birmingham; Staires Farm, near 

 Newnham-on-Severn, Gloucestershire (where I have taken several specimens under 

 bark of old pear trees in January) ; my wife once found a specimen in my study at 

 Repton, but it had probably come out of old wood from the Mew Forest; Carlisle 

 (under bark of elms) ; Scotland, very rare, Forth and Tay districts. 



H. nigricornis, F. Rather smaller on an average than the pre- 

 ceding, which it very closely resembles, and chiefly distinguished by its 

 colour, which is dark bluish-green, or greenish-blue, with a bronze 

 reflection ; the pubescence is, perhaps, a little paler ; the legs are some- 

 what variable in colour, the tibiae being either clear yellow or more or 

 less infuscate, and the femora being more or less dark ; the punctuation 

 of the elytra is rather coarser and more diffuse than in //. impressus, and
