Agathidium.] CLAVICORNIA. 17 



pitchy ; legs reddish or brownish-red, posterior femora sometimes 

 blackish, without distinction in the sexes. L. 2 mm. 



In moss, dead leaves, rotten wood, &c ; London district generally distributed and 

 common ; Dover; Hastings; Glaiivilles Wootton ; New Forest; Isle of Wight; 

 Kuovvle; Dudley; Buddon Wood, Leicestershire; Chat Moss; Bold records it as 

 very rare in the Northumberland district, and says he has only one local specimen ; 

 Scotland, Lowlands and Highlands, among moss, common, Solway, Forth, Tay, Dee, 

 and Moray districts ; it appears probable from the Scotch record that the species has 

 been overlooked in the northern counties of England. 



A. margrinatum, Sturm. A small species, globose, pitchy-black or 

 black with the extreme margins of thorax, and the apex of elytra more 

 or less broadly, pitchy-brown ; head extremely finely punctured, antennae 

 reddish with the club, except apical joint, blackish ; thorax short, scarcely 

 as broad as elytra, narrowed in front, broadest behind, very finely and 

 scarcely visibly punctured ; elytra thickly and distinctly punctured 

 without sutural stria ; legs brownish-red, posterior femora blackish 

 L. li-l|mm. 



Male with the anterior tarsi slightly dilated, the apex of elytra less 

 deflexed, and the left mandible rather strongly developed ; female with 

 all the tarsi 4-jointed. 



In haystack and flood refuse, &c. ; not common ; Caterham, Forest Hill, Weybridge, 

 Horsell, Sheerne'ss, Chatham ; Deal ; Hastings ; Littlington ; Norfolk fens (specimens 

 variable in size) ; Wallasey, near Liverpool ; Northumberland' district, widely dispersed 

 but not common ; Scotland, very rare, Forth district ; also taken by Mr. Bold at 

 Tain, Ross-shire. Ireland, Portmarnock. 



A confusum, Bris. (clypeatum, Sharp, polonicum, Wank., picvum, 

 Thorns, nee. Er., mandibulare, W.C., iiec. Sturm.). Very like the pre- 

 ceding in size, shape, and colour, but easily distinguished by having the 

 clypeus distinctly, although shal lowly, emarginate, and by the presence 

 of a sutural stria on elytra reaching from apex to about middle ; the 

 elytra are distinctly, although finely punctured ; in the female the tarsi 

 are all 4-jointed, arid in the male the left mandible is considerably 

 developed. L. l-l|'mm. 



In fungi ; very rare ; New Forest, Lyndhurst (Sharp) ; Headley Lane (E. W. 

 Janson) ; Northumberland district, North Seaton (Bold) ; Dr. Power is said to have 

 taken a specimen, but I have not noticed it in his collection. 



In the catalogue of Heyden, Eeitter, and Weise (1883) this species is 

 given as synonymous with picewn, Er. ; I have, however, followed the 

 synonymy given by Eeitter himself in the Bestimmungs-Tabellen der 

 Eur. Col. Necrophaga, published in 1885. 



A. varians, Beck. Colour very variable, sometimes entirely tes- 

 taceous, with the disc of thorax and base of elytra darker, sometimes 

 dark, with the head and margins of thorax, and apex and margins only 

 of elytra light ; head large, sparingly and very finely punctured ; 

 antennae reddish-yellow, with the two first joints of the club blackish ;
