more coarsely punctured ; biud body moderately 



long S. INTEEJIEDIUS, JEn 



II, Elytra distinctly longer than thorax, with apex more 



or less broadly testaceous. 

 i. Head evidently longer than broad ; elytra with 



apical testaceous border broad reaching from side to 



side S. DIVBBSU5, Aub^. 



ii. Head subquadrate, about as long as broad ; elytra 



with apical testaceous border usually margined with 



black nearly to apex, sometimes taking the form of a 



double spot S. anqustatps, Pai/Jc. 



S. filiformis, Latr. {procerus, Grav., exfensus, Mannh.). Very 

 elongate, narrow, and linear, dull black, with the three last segments of 

 hind body shining, apex of elytra broadly testaceous ; head slightly 

 longer than broad, rather finely and very thickly punctured ; antennae 

 testaceous, slender, with the third joint longer than second, and joints 

 4-10 oblong ; thorax somewhat cordilorm, with sides strongly narrowed 

 behind, rather finely, very thickly and rugosely punctured ; elytra 

 narrow, longer than broad, slightly longer than thorax, rugosely and very 

 thickly punctured ; hind body very long, rather finely and thickly 

 punctured on the first three segments, less closely on the rest ; legs 

 testaceous, with posterior coxse dark. L. 4| mm. 



Male with the seventh ventral segment of hind body narrowly and 

 very sharply excised at apex, sixth very feebly sinuate. 



In moss, at roots of grass, &c,, generally in chalky or sandy places near the coast ; 

 rare; Kemp Town, Brighton, in some numbers (Power); Whitsand Bay, Plymouth 

 (J. J. Walker) ; Forest Hill and Burntash Lane (Power) ; Tewkesbury (Blatch). 



S. intermedius, Er. (imwacidatus, Steph.). This species is easily 

 distinguished Irom the other British species by having the elytra to all 

 intents and purposes entirely black, the apical margin being so narrowly 

 testaceous that it is often hardly apparent ; the elytra, moreover, are 

 more coarsely punctured than in any of the other species ; in this 

 character, however, there appears to be some variation ; in the male the 

 sixth ventral segment of hind body is obsoletely impressed longitudinally 

 in centre, and broadly sinuate at apex, and the seventh has a sharp 

 angular emargination. L. 3|-3f mm. 



In haystack refuse; also in moss, flood refuse, &c., in marsliy places ; local, but 

 sometimes very abundant where it occurs ; Lee, Sheeruess, Toubridge ; Harwich ; Sand- 

 wich ; Holm Bush, Brighton ; Isle of Wight, Luccombe Chine, &c. ; Llangollen ; 

 Tewkesbury. 



S. diversus, Aube {pulchellus, Heer, fasciatus, Mots.). In 

 general shape much the same as S. Jiliformis, except that the hind body 

 is not so elongate ; head longer than broad, hardly as broad as thorax, 

 head and thorax very thickly and rugosely punctured ; elytra evidently 

 longer than thorax rather strongly and thickly punctured ; hind body a 

 little dilated behind middle, rather finely, thickly, and somewhat
