Tf. albirostris, Henne Gaines ae black ; rostrum compara- 
tively long with white squamose pile ; eyes somewhat approximating on 
forehead ; antennz black; thorax narrowed in front, with an elevated 
and ‘scarcely undulated, almost straight, carina at base, moderately punc- 
tured, disc with two plain fovez and two others more or less obsolete ; 
elytra with a whitish patch at scutellum, and a large white patch at 
apex, the latter variegated with black ; towards the suture there is a 
series of velvety black tufts; legs dark, annulated with white. L. 4-5} 
mm. 
In dead wood of beech, oak, and certain species of poplar; extremely rare; on 
palings near Norwich (Stephens) ; I know of no other record and the species, perhaps, 
requires further confirmation as indigenous; it has occurred in Sweden, Central 
Europe, and Hastern Siberia. 
T. niveirostris, F. Allied to the preceding, from which it may 
easily be known by its much shorter rostrum, which is scarcely dilated 
at apex, and by having the thorax even and not foveolate; dusky 
black, with the antenne pale ferruginous, and the rostrum and head, 
scutellum, and apex of elytra thickly clothed with snowy scales: there 
are also patches of ashy pubescence on the thorax and elytra, inter- 
mingled on the latter with velvety black patches; the basal carina or 
raised line on thorax is slightly sinuate at the sides; legs variegated 
with white pile, tibize and tarsi more or less ferruginous. L. 33-43 mm. 
Male with the antennz longer and the posterior tibie with a hook 
at apex. 
In dead branches of oak, hazel, beech, and lime; by beating dead hedges and 
faggot stacks in woods; very rare; New Forest, June, 1831 (Hope) ; Coombe Wood 
and Shirley (Stephens) ; Darenth Wood (Champion) ; near Farnham, Surrey (Power) ; 
West Wickham (Power) ; Buddon Wood, Leicester, September 10th, 1860 (Plant). 
T. sepicola, I. (ephippiwm, Boh.). Allied to the preceeding, but 
easily distinguished by the fact that the thorax has two black fascicles 
or tufts of raised pile on the middle of disc, and the elytra a common 
velvety-black dorsal patch, which is usually large; the general colour 
is black variegated with ashy; the antenne are red, with the third 
joint shorter than the fourth; the elevated basal keel of the thorax is 
almost straight, and the eyes are broadly distant on the forehead and 
somewhat prominent. L 33-45 mm. 
In woods, in dead branches of oak and hornbeam ; extremely rare ; a single example 
was found on August 18th, 1856, by Mr. I’. Plant, of Leicester, “in a decayed oak- 
bough, of which he carried home a bag full for examination from Buddon Wood, 
near Quorndon, Leicestershire’? (Ent. Annual, 1857, 84).
