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, Ac. ; occasionally found in moss 

 and dead leaves, and in sand-pits ; not uncommon in many localities ; Bishops Wood

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, antennae 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 striae, 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, Cooinbe Wood, Forest Hill, Darentb,

CETJTHORRHYNCHINA. 



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 coxae which are 

 distant ; in certain genera, however, the rostrum is short and stout and 

 not, or scarcely received ; the antennae 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 coxae are small 

 and do not 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 coxae " 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 apical margin of the elytra rests." 



The Ceuthorrhynchina appear to be diurnal in their habits and are 

 found on various plants, especially Cruci/erce ; as a rule, when alarmed,
