apex of the third and fifth interstices, will easily distinguish this species 
from the preceding. L.2-3 mm. 
Heathy places; by beating dead branches of fir, &c. ; occasionally found in moss 
and dead leaves, and in sand-pits ; not uncommon in many localities ; Bishops Wood

Plumstead, Wickham Wood, Weybridge, Tonbridge, Ripley, Chatham; Hertford ;

Robins Wood, Repton; Northumberland and Durham district, very rare, Gibside ; 
Scotland, rare, Solway and Forth districts. 
A. turbatus, Boh. (misellus, Boh. ; echinatus, Germ.). This species 
may easily be distinguished from the two preceding, to which it is closely 
allied, by the comparatively long erect black scales on the thorax and 
elytra, which are more distinctly visible if the insect is viewed sideways; 
the upper surface is also clothed with more or less irregular ashy or 
yellowish ashy scales ; rostrum, antenne and legs ferruginous, the former 
almost smooth ; thorax longer than broad, slightly constricted before apex, 
sides rounded, closely and strongly punctured, even; elytra very con- 
vex, with deep and deeply punctured striz, interstices narrow and con- 
vex. L. 2-3 mm. 
By beating dead hedges; in poplar faggots, &c.; very local but not uncommon in 
the London and southern districts ; Mickleham, Coombe Wood, Forest Hill, Darenth,

CEUTHORRHYNCHINA. 
This is a large and important tribe, containing a considerable number 
of genera and several hundred species ; by far the majority are found in 
the Palearctic region, although representatives of the genera are found 
widely distributed over the surface of the globe; they are, with very 
few exceptions, small short and broad insects, with the rostrum, as a 
rule, long and slender, and received in a distinct pectoral groove, which 
is variable in length and depth, between the anterior coxe which are 
distant ; in certain genera, however, the rostrum is short and stout and 
not, or scarcely received; the antenne have the funiculus either 6- or 
7-jointed ; the prosternum is often excised at apex, but is in many cases 
only broadly emarginate or even truncate ; the posterior cox are small 
and donot reach the episterna of the metathorax ; according to Leconte 
and Horn the members of the tribe may be distinguished from their 
allies with distant front coxe “by the pygidium being perpendicularly 
deflexed, and marked with a deep excavation (as in Mononychus), or 
with a continuation of the acute lateral margin of the ventral segments, 
against which the apieal margin of the elytra rests.” 
The Ceuthorrhynchina appear to be diurnal in their habits and are 
found on various plants, especially Crucifere ; as a rule, when alarmed,
