222 RHYNCHOPHORA. [ Sitones. 
legs are black; the scales are variable in colour and are sometimes 
greenish or slightly coppery. L. 3-4 mm. 
Male with the anterior tibie rather strongly curved and armed with 
a moderately strong hook at apex; fifth segment of the abdomen sub- 
truncate at apex. 
Female with the anterior tibie slightly curved and armed with a small 
hook ; fifth segment of abdomen slightly impressed before apex. 
On broom, furze, clover, heath, &c. ; common and generally distributed through- 
out the kingdom. 
S. brevicollis, Schénh. Allied to the preceding, of which it has 
by some authors been regarded as a variety ; it may, however, be distin- 
guished by its shorter thorax and, on the average, smaller size; the 
rostrum is slightly narrowed at apex, with the central furrow more 
distinct in front; the antenne are black, with the scape paler at base, 
but this does not appear to be always a reliable character; the thorax 
has the sides slightly rounded, as in S. tibialis, but is evidently shorter; 
the elytra are more convex on the back behind, and wider, sparingly 
clothed with smaller shining scales (the margins, suture, and two dorsal 
lines being more closely covered with paler scales), with the punctuation 
of the stria more evident, and the short sete brown (not alternately 
light), and more dense, especially behind. L. 38-35 mm. 
Apparently rare, but perhaps overlooked ; recorded by Dr. Sharp as not uncommon 
in the South (see Ent. Annual, p. 81, from which the above description of the differ- 
ences pointed out by Thomson is taken) ; Birch Wood (Rye and Power) ; Matlock 
(J. T. Harris) ; Scotland, local, Sclway district (Sharp). 
S. hispidulus, F. Black, clothed with fuscous-brown scales; 
head short, deeply punctured, with a distinct central channel; antenne 
red with the club fuscous ; eyes quite flat ; thorax with the sides slightly 
rounded, deeply and diffusely punctured, interspaces very finely sculp- 
tured, with three lighter lines, of which the central one is often more or 
less obsolete ; elytra with rather deep punctured strive, with fuscous- 
brown scales variegated with small black patches, and stiff outstanding 
sete ; femora dark, tibiz and tarsi testaceous ; the elliptic form, flattened 
eyes, strong and remote punctuation of thorax, and short stiff grey 
bristles, will easily separate it from all our other species. L. 3-4 mm. 
Male with the anterior tibiz curved at apex and armed with rather a 
strong hook, and the fifth segment of the abdomen almost truncate at 
apex; in the female the same segment is rounded. 
On clover ; by sweeping, especially in sandy places ; the larva lives at the roots of 
the plants; common and generally distributed throughout the greater part of the 
kingdom, but not so plentiful in Scotland, where it appears to be somewhat local; in 
some districts it is as abundantas S. lineatus. 
S. humeralis, Steph. In size and general appearance this species 
somewhat resembles, at first sight, the preceding insect, but may easily
