222 RHYNOHOPHORA. [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 tibia? 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 tibiae 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, Schonh. 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 antennae 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 strias more evident, and the short setae brown (not alternately 

 light), and more dense, especially behind. L. 3-3| mm. 



Apparently rare, but perhaps overlooked ; recorded by Dr. Sharp as not uncommon 

 in the South (see Knt. 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, Sdvvay district (Sharp). 



S. hispidulus, F. Black, clothed with fuscous-brown scales; 

 head short, deeply punctured, with a distinct central channel ; antenna? 

 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 strife, with fuscous- 

 brown scales variegated with small black patches, and stiff outstanding 

 setee ; femora dark, tibiae 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 O\\TL other species. L. 3-4 mm. 



Male with the anterior tibise 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 abundant as S. lineatus. 



S. humeralis, Steph. In size and general appearance this species 

 somewhat resembles, at first sight, the preceding insect, but may easily
