Rhynehites. | RHYNCHOPHORA. 125 
behind, evidently shorter in proportion, and much more closely and 
finely punctured; central furrow wanting ; pubescence shorter and less 
raised; elytra with a scutellary stria and with deeply punctured striae, 
and the interstices very finely punctured, often almost smooth, ninth 
stria entire and prolonged as far as the tenth stria ; legs black or blue- 
black. L. 2-25 mm. 
On young trees in woods, especially oaks ; often found by sweeping herbage; very 
widely distributed and common in many localities, but local in the midlands and 
rarer further north; Scotland, scarce, but found in the Solway, Tweed, Forth, Clyde, 
Moray, and probably other districts. 
R. interpunctatus, Steph. (alliarie, Brit. Cat.). Extremely 
closely allied to the preceding, and rather hard in some cases to dis- 
_ tinguish from it ; it may, however, be known by having the ninth stria 
of the elytra abridged and united to the tenth considerably before 
apex; from #. ceruleus it may be known by the more finely-punctured 
thorax and less evident pubescence, and from Rt. pauxillus by the absence 
of a central furrow on thorax which is less coarsely punctured, as well as 
by the shape of the head, which is not sensibly narrowed behind, and 
the fact that the interstices of the elytra are furnished with single rows 
of punctures. L. 2-25 mm. 
On young trees, in woods and hedges; not common; Darenth Wood; Birch 
Wood; New Forest; Glanvilles Wootton; Swansea; Ireland, near Dublin, &e. 
There is considerable confusion regarding this insect which stands in 
our collection as &. alliarie, a name which has been applied to allied 
species ; I cannot, therefore, be sure of the localities ; some authors state 
that it has no scutellary stria, but according to Bedel this is present, 
and such is the case with a specimen of mine from Dr. Power's 
collection. 
R. pauxillus, Germ. Closely allied to the three preceding 
species, but easily distinguished by the deep central furrow on the 
thorax ; it may further be separated from R. interpunctatus as above 
stated, from 2. minutus by having the ninth stria of the elytra abridged 
and united to the tenth considerably before apex, and from both by the 
coarser punctuation of the thorax ; from &. ceruleus the less evident 
pubescence and the presence of a scutellary stria will serve to distinguish 
it ; the interstices are almost smooth. L. 2-24} mm. 
On various Pomacee, especially the medlar; also on the sloe; it also has been 
taken on young oaks, hazels, &c.; rare; Darenth Wood (Champion) ; Shirley, on 
whitethorn hedges (S. Stevens) ; Littlington, Cambridge (Power) ; Knowle, near 
Birmingham (Blatch) ; Northumberland and Durham district, very rare; Scotland, 
very rare, Solway district, ‘ Kirkpatrick-Juxta. Rev. W. Little. Murray’s Cat.” 
These four species appear to present great difficulties to students of 
the group, but R. minutus and R. interpunctatus are the ouly ones that 
could be confounded ; the rostrum is longer in these and, in fact, in most 
of the species of the genus, in one of the sexes, according to Thomson
