16 CJAVICORNIA. [Agathidium, 



Rcpton ; Darlington ; Ripon ; Manchester district ; Northumberland district, not 

 uncommon in many localities, Wellington, Gosforth, Jesmond, Ravensworth, Whittle 

 Dene, &c. ; Scotland, rare, at oozing sap of trees, Forth and Clyde districts ; I have 

 also received it from Ireland from Mr. J. J. Walker, who has found it at Wustport 

 (Co. Mayo) and Rathmullan (Co. Donegal). 



A. at rum, Payk. Shining black, with the margins of thorax and 

 usually the extreme margin of elytra pitchy; under-side blackish or 

 pitchy with apex lighter ; antennae reddish-brown with the two first 

 joints of the club darker and the last joint lighter ; head thickly and 

 distinctly punctured ; thorax ample, very finely punctured, much more 

 so than head and elytra, broadest behind middle, with all the angles 

 rounded ; elytra finely but plainly punctured, with a distinct sutural 

 stria reaching from apex to beyond middle ; legs reddish-brown, posterior 

 femora often blackish. L. 2f mm. 



Male with the posterior femora produced into a tooth at apex, and the 

 metasternum in middle furnished with a little bunch of hairs. 



In dead leaves, moss, fungi, &c. ; rather local, hut, as a rule, not uncommon ; 

 London district, generally distributed ; The Holt, Farnham ; Hastings ; Swansea ; 

 Yardley; Sutton Park ; Cannock Chase; Needwood; Sherwood Forest; Langworth 

 Wood, Lincoln ; Manchester district ; Northumberland district rare, but rather 

 widely distributed ; Scotland, Lowlands and Highlands, not rare, Solway, Tweed, 

 Forth, and Tay districts. 



A. seminulum, L. Lighter or darker pitchy brown, sometimes red- 

 dish brown, with the margins of thorax and elytra lighter, and the under- 

 side always reddish-brown, a character, which together with its smaller 

 and narrower form, will easily separate dark examples from the preceding 

 species ; antennas reddish-brown with yellowish club ; head very finely 

 punctured; thorax scarcely visibly punctured, with sides strongly rounded, 

 broadest before middle, and if viewed when quite level apparently 

 dilated in front ; elytra finely but distinctly punctured, with a sutural 

 stria reaching from apex to about middle; legs reddish. L. 2 mm. 



Male with the posterior femora produced at apex into a rounded 

 angle. 



In dead leaves, moss, rotten wood, &c. ; local ; London district, not uncommon ; 

 St. Leonard's Forest, Sussex; New Forest; Southampton; Parkhurst Forest, Isle 

 of Wight, in nests of F. rufa (J. J. Walker) ; Dean Forest, common ; Colesliill ; 

 Knowle ; Cannock Chase ; Sherwood Forest ; Chat Moss ; Reptou ; Ripon ; not 

 recorded from any locality in England further north than Yorkshire, or from 

 Scotland. 



A. lacvig-atum, Er. This species is easily distinguished by its 

 smooth and impunctate surface and the absence of a sutural stria on 

 the elytra ; it is black or pitchy, with the margins of the elytra distinctly 

 reddish-brown; antennae brownish-red, with the first two joints of the 

 club brown, and the last lighter ; thorax very broad, broader than elytra, 

 widest about middle ; elytra smooth ; under-side black, abdomen sometimes
