and more cylindrical ; the head and thorax are rather shorter and 

 broader, and the general punctuation of head, thorax, and elytra is 

 closer and more regular ; the general colour is a deeper black, and the 

 apical joint of the palpi is black instead of clear red ; the seventh 

 ventral segment of the hind body of male is also more deeply emarginate. 

 L. 6 mm. 



Very rare ; Scotland, Solway and Forth districts, a few specimens taken by Dr. 

 Sharp ; the species is very distinct from L. punotat.um, but it is apparently not quite 

 certain whether it is really the L. atripalpe of Scriba. 



Xi. filiforme, Grav. {impressum, Heer.). Shining black with the 

 mouth parts red, antennae red, legs pitchy red ; very like L. puncfatum, 

 but smaller and narrower and a little less depressed; the head is more 

 oval, and more finely and thickly punctured ; the thorax is narrower and 

 more oblong, much longer than broad ; the legs are darker, and the hind 

 body more shining ; in the male the sixth and seventh ventral segments 

 of the hind body are very narrowly impressed, and the latter is angularly 

 excised on apical margin instead of being circularly emarginate as in 

 L. pundatum ; as in other species there are two forms, one with longer 

 elytra and winged, the other with shorter elytra and apterous. L. 5 

 mm. 



Marshy places, in moss, flood refuse, &c. ; rare; Walton-on-Thames; Hammer- 

 smith and Notting Hill (formerly) ; Amberley ; Scotland, Forth district, but perhaps 

 in error (Sharp, Scottish Naturalist, vol. iii. no. xvii. p. 33) ; Ireland, near Water- 

 lord (Power). 



- 1,. quadratum, Payk. Black, head and thorax very shining, elytra 

 less shining, hind body almost dull with rather thick and tine greyish 

 pubescence ; head suborbicular, finely and thickly punctured at sides, 

 sparingly on disc ; antennae long and slender, dark pitchy red, with all 

 the joints elongate ; thorax oblong, plainly narrower than elytra, finely 

 and thickly punctured at sides, more strongly and sparingly on disc, with 

 a narrow smooth central line ; elytra plainly longer than thorax, 

 depressed longitudinally near suture, finely, thickly, and somewhat 

 rugosely punctured ; hind body very finely and thickly punctured, 

 gradually narrowed from middle to apex ; legs pitchy, Avith tarsi, and 

 usually knees, lighter. L. 6 mm. 



Male with the seventh dorsal segment broadly rounded on apical 

 border, seventh ventral segment rather deeply and angularly excised, 

 female with seventh ventral segment truncate and ciliate.
