S. nigrra, L. (s.g. Stenura, Drj.). Elongate, slender, entirely 

 black moderately shiny, with the abdomen rufous, the base and rarely 

 tin- apex being more or less black ; upper surface clothed rather sparingly 

 with fuscous pubescence, under-side clothed thickly with greyish

 line, antennae nearly as long as body ; thorax longer than broad, much 

 narrowed in front, finely and sparingly punctured ; elytra more strongly 

 punctured than thorax, the punctuation being somewhat asperate, apex 

 slightly emarginate ; in the male the metasternuin is bicristate in the 

 middle. L. 8-10 mm. 



On flowers in woods ; local, and not common, although sometime* taken in some 

 numbers where it occurs ; Durenth Wood, Dulwich, Ripley, Coombe Wood, Ton- 

 bridge, Westerham ; Shipley, near Horshum ; Norfolk ; Suffolk ; New Forest ; 

 Devon ; Swansea ; Bewdley Forest ; it has not apparently been found further north 

 than the Midland districts. 



S. melanura, L. (s.g. Stenura, Dej.). Broader than the preceding 

 species, black, clothed with scanty pubescence above, and thick greyish 

 pubescence beneath, elytra coloured differently in the sexes ; head and 

 thorax thickly and strongly punctured, the latter longer than broad, 

 much narrowed in front ; elytra less closely and not so strongly punc- 

 tured as thorax, more finely behind, apex slightly emarginate ; legs 

 lung. L. 6-10 mm. 



Male with the elytra livid testaceous, the apex being broadly, and 

 the suture narrowly, black ; fifth ventral segment subtruncate at apex. 



Female with the elytra bright red, the apex and suture being very 

 broadly black. 



On flowers ; generally distributed and common from the Midland counties south- 

 wards ; rarer further north ; Burnt Wood, Staffordshire ; Northumberland and 

 Durham district ; not recorded from Scotland. 



GRAMMOPTERA, Serville. 



This genus is sometimes included under Leptura, and one of the 

 species, G. tabacicolor, is placed in a separate sub-genus Alosterna by 

 Mulsant; the species are distinguished by their parallel, and in most 

 cases subcylindrical form, and by having the posterior angles of the 

 thorax, produced in a spine at apex; they are comparatively sm ill 

 insects ; about thirty species are comprised in the genus, which arc all 

 described from Europe and the Caucasus district, Northern Asia, and 

 North America, with the exception of one from Asia Minor, and one 

 from Algeria ; all the European species occur in Britain ; they may be 

 extinguished as follows : 

 I. Klytra testaceous with suture narrowly black . . . O. TAUACICOI.OB, De O.
