O. fuscum, Grav. (laticolle, J. Sahib.). Either shorter, more 

 depressed, and narrower tlian tlie preceding, and, as a rule, more darkly 

 coloured ; the head is often quite black anil the disc of thorax is some- 

 times much darker tlian the margins ; the thorax is longer and less 

 transverse, being only about one and a half times as broad as long, and 

 its side margins are more strongly raised than in 0. inceum ; the scu- 

 tellum is furnished with one or two or more punctures (the distinctions, 

 however, drawn from the punctuation of the scutellum in this genus are 

 very unsatisfactory) ; the elytra are narrower, and their punctuation is 

 arranged in more or less irregular but distinct rows near suture. L. 4 

 mm. 



lu niosi!, &c. ; very local ; rare in England, Colesliill, Sutton Park, BowtUey and 

 Matlock (Blateb) ; Scarborough ; Scotland, Lowlands, local, Solway and Fortli dis- 

 tricts : it is worthy of notice how many of the northern species have been found by Mr. 

 W. G. Blatch in various Midland localities, especially in Bewdley Forest aud on 

 Cannock Chase. 



O. consixnilc, Gyll. (limhalum, Miikl.). ISTarrower than the pre- 

 ceding and somewhat longer ; it may, however, be easily distinguished 

 from both the other species by having the sides of the thorax slightly 

 sinuate behind middle, so that the posterior angles, instead of being 

 rounded, are somewhat prominent ; the elytra are longer in proportion ; 

 the scutellum appears to be always deeply and diffusely punctured. L. 

 4-5 mm. 



In wet moss and banks of streams on mountains, often near the snow ; very local 

 and rare ; Scotland, Dee district (Braemar).

This genus comprises about a dozen species, which appear to be dis- 

 tributed much as those belonging to the two or three preceding genera : 

 Kraatz mentions an undescribcd species from Chili, but I can find no 

 further record of it ; our species are small insects, much resembling 

 OlojyJirum in form, but much smaller and lighter coloured; they are 

 found in decaying fungi, moss, dead leaves, &c. ; the sexual differences 

 are as in the preceding. 



I. Head black or dark pitchy brown ; thorax with distinct 



central farrow ; size smaller L. ATROCEPHALUJI, Oi/ll. 



II, Head yellowish-red ; thorax with central furrow 

 obsolete and abbreviated and often absent ; size 



larger L. unicoloe, Steph. 



Zi. atrocephalum, Gyll. {nee Ileer) {melanocejilialum, Marsh, nee 

 111.). Sliort and broad, somewhat oblong, convex, rufo- testaceous with 

 head black or dark brown, shining ; antennae thickened towards apex, 

 rather long, testaceous with apex pitchy ; head small, thickly and 

 deeply punctured behind, smooth and shining in front ; tliorax at base 

 a little narrower than elytra about twice as broad as long, with sides
