Pityophthorus.| RHYNCHOPHORA. 435 
brown, moderately shining, antenne and legs reddish brown; thorax 
longer than broad, hardly narrowed in front, apex bluntly rounded, 
anterior exasperations concentrically disposed, punctuation of hinder 
part fine and scattered ; elytra produced at apex—not obtusely rounded 
—with fine punctuation ; the apical depressions are distinct, deep and 
rather dull, with their outer margins raised, convex and shining, without 
punctures, but with distinct setigerous tubercles, which are also present 
on the raised sutural margins. L. 13-13 mm. 
As before remarked, no authentic British specimens of this species are 
known, as all that have hitherto been examined must be referred to one 
of the two preceding ; it is, however, very probable that it exists in our 
collections ; it is especially attached to the spruce-fir. 
The longer shape, brighter colour, and finer punctuation, as wellas the 
acuminate elytra will distinguish this insect from either of the other 
species). 
The members of the genus can be taken in localities where they occur, 
by examining the smaller terminal shoots and branches of Conifer 
brushwood ; most of the species breed in these and do not touch the 
bark of large branches; P. micrographus, however, appears to be an 
exception to this rule. 
XYLOCLEPTES, Ferrari. 
This genus contains three species, one of which is found in Europe, 
and the others have been described from Venezuela and Bogota; 
X, bispinus, the single European species, is exclusively attached to 
species of Clematis ; it may be known by having the second joint of the 
club of the antennz crescent-shaped and completely embracing the sides 
of the first; the funiculus is five-jointed ; the scutellum is indistinct, 
and the apical portion of the elytra is strongly inflexed in the male and 
feebly inflexed in the female. 
x. bispinus, Duft. Cylindrical, chestnut brown, shining, clothed 
with rather scanty long upright greyish hairs, which are very distinctly 
visible if the insect is viewed sideways ; thorax longer than broad, 
scabrous in front, with the angles rounded ; scutellum scarcely dis- 
tinct ; elytra with moderately fine and rather close punctured strizx. 
L. 2-3} mm. 
Male with the thorax shining and diffusely punctured behind ; apex 
of elytra much inflexed, raised at suture and armed with a large sharp 
tooth. 
Female with the thorax dull and shagreened behind, except on the 
central line ; apex of elytra feebly inflexed with the suture and raised 
edges projecting and finely tuberculate.
