and Forth districts ; it probably occurs in Ireland, but I do not kuow of any record ; 
this species seems very generally distributed, especially in the Midland counties, and 
is recorded by many collectors as common, but I have never yet seen it alive. 
RHYNCHITINA. 
This tribe contains a few genera of which by far the most important is 
Rhynchites ; its members are distinguished from the Attelabina by 
having the external border of the mandibles cut out into large teeth, and 
by the free tarsal claws, which in most eases are appendiculate, and also 
by the fact that the epimera of the mesosternum almost reach the 
intermediate coxe and the apices of the prosternal epimera either meet 
or are separated by a small and narrow centro-sternal piece; the proster- 
num is very short before the anterior cox; a large number of the 
species are brilliantly coloured and very conspicuous insects ; our three 
British genera have been by many authors united under Rhynchites, 
but must be regarded as separate. 
I. First ventral segment of the abdomen lobed on eaci side 
between the posterior coxze (the outer portion of which is 
covered and concealed) and the side pieces of the meta- 
sternum ; upper surface glabrous or only finely aise 
towards apex of elytra . . . Bycriscus, Thoms. 
Il. First ventral segment of the abdomen not lobed, so that 
the posterior cox appear larger and moré transverse and 
visibly attain to the side pieces of the metasternum ; upper 
surface pilose or pubescent. 
i. Apices of prosternal epimera meeting; abdomen with 
the pygidium only exposed; vertex of head not or 
scarcely constricted behind. . . . Raynes, Schneid. 
ii. Apices of prosternal epimera narrowly "separated by a 
centro-sternal piece ; pygidium and propygidium as a 
rule exposed *; vertex of head large, strongly con- 
atrictedibehind) eis) acl) J. se rsliaukt wt fas DEPordusy Leach. 
BYCTISCUS, Thomson (Rhinomacer, Geoffroy, nec F.). 
The species belonging to this genus may be distinguished by the 
formation of the posterior coxe and of the first ventral segment of the 
abdomen ; the thorax is subglobose and is armed on each side in the 
male with a long produced spine ; the upper surface is glabrous or almost 
glabrous ; they are found on various trees; the female rolls the leaves 
into the form of a cigar and lays her egas in the dwelling thus con- 
* In Deporaus mannerheimti, as pointed out by Dr. Sharp, the male has only: the 
pygidium exposed (Trans. Ent. Soe. London, 1889, Part I. p. 70.)
