A. hzmorrhous, Herbst. (scortillum, Herbst.). Short convex, 
pitchy black, upper side subglabrous, slightly shining, underside 
thickly clothed with white seales ; upper surface of thorax and elytra 
strewn with very small greyish scales which are thick at base of 
suture and form a spot; base of antenne and legs red; rostrum long ; 
thorax long, scarcely transverse, gradually constricted before apex, 
closely punctured, with the sides rounded and without lateral tubercles 
or central furrow ; elytra subglobose, broadly reddish at apex, with 
strong punctured striz and narrow convex interstices, which are not 
muricate at apex ; legs moderately long. L. 14 mm. 
Male with the intermediate tibiz armed with a small hook.

district, Kent and Surrey, and South East Coast, generally distributed ; Ipswich ;

RHINONCUS, Stephens. 
About a dozen species are known as belonging to this genus, which 
appear to be somewhat widely distributed as single specimens have been 
recorded from India and the Cape of Good Hope; they are short, thick- 
set insects with the rostrum stout, the eyes large and round and strongly 
prominent, the thorax not strongly constricted before apex, the femora 
simple, the prosternum not excised at apex, and the anterior cox distant ; 
the tarsal claws are appendiculate on their innerside; the species are chiefly 
found on Rumex ; the larve live on the stems of the plants and devour 
the centre and fleshy portions ; as a rule they appear to form a cocoon in 
which they undergo their final transformations; as observed above, some 
of the species have the power of leaping sideways, notably R. perpen- 
dicularis (subfasciatus) ; this power is not strongly developed, and, as far 
as my own observation has gone, the insect does not appear to make much 
use of it; it appears to be a protective property in course of develop- 
ment and is rather strange as being opposed diametrically to the usual 
protective habit of the Ceuthorrhynchina which is to shut the legs and 
rostrum beneath the body and remain quite motionless. 
All the European species, with the exception of R. albocinctus, Gyll., 
are found in Britain; they may be separated as follows:— 
J. Anterior margin of thorax without tubercles in 
middle. 
i. Interstices of elytra rugose but without distinct 
tubercles or asperities. 
1. Form short and broad; size larger; elytra not, 
or only slightly, longer than together broad. 
A. Sides of thorax without a distinct tubercle; 
striee of elytra nearly as broad as the inter-
