as well as by the thorax being broadest at base ; the species is very rare 

 en the Continent, as far as it is at present known, but has been taken by 

 Dr. Sharp in some numbers in Scotland among bones and hides. 



E. saxonicum, Gill. Oval, convex, fuscous, thickly clothed with 

 pale pubescence ; head broad, eyes large, not prominent, antenna yellow, 

 rather long and slender; thorax large, subquadrate, with sides gently 

 rounded, widest at base, very closely covered with moderate-sized, 

 tubercles, posterior angles right angles ; scutellum very small ; elytra 

 rather long, with sides slightly rounded, completely covering abdomen, 

 deeply asperate, and appearing as if reticulate, apices very broad, sutural 

 angles obtuse ; legs yellow, tarsi rather short ; under-side fuscous, with 

 the mouth, coxae, and apex of abdomen lighter. L. -* |- mm. 



Under bones and hides ; taken in some numbers by Dr. Sharp in the Dee and 

 Solway districts of Scotland. 



NOSSXDZUXK, Erichson. 



This genus contains two European species and one or two from 

 America ; from Euryptilium it is distinguished by its larger size, and 

 oval and more convex form, and by the structure of the skeleton of the 

 under surface of the body ; from all our other allied genera it may be 

 known by having the thorax broadest at base ; its oval-convex shape and 

 strong pubescence give it an appearance different from the ordinary 

 Trichopterygidse, and at first sight it looks as if its affinities were rather 

 towards certain members of the Corylophidse. 



N. pilosellum, Marsh. (Ferrarii, Eedt. ; v. Irunneum, Marsh. ; v. 

 nitidulum, Marsh.). Broad and ovate, very strongly convex, castaneous, 

 but variable in colour, the head and thorax being often darker than the 

 elytra, thickly clothed with long yellow pubescence ; head short, eyes 

 somewhat prominent, antennae clear yellow ; thorax large, much longer 

 and broader than head, dilated behind, widest at base, with sides 

 slightly rounded, and rather plainly margined, posterior angles acute, 

 not produced, remotely punctured ; elytra broadest at shoulders, semi- 

 ovate, deeply punctured, with the interstices rugose, narrowed at apex ; 

 legs rather long, clear yellow, anterior tibiae dilated at apex. L. 1-1 1 

 mm. 



On rotten stumps or in damp rotten wood ; also in fungi, dead leaves, &c. ; found 

 rather rarely, but locally abundant ; Birch Wood and Claygatc (Champion) ; Darenth 

 (Power); Littliugton (Power); Hunstanton, Norfolk (Blatch); Needwood Forest 

 near Burtoii-ou-Trent (Gorhaui). 



PTENIDIUBI, Erichson. 



This genus contains at present upwards of thirty species from Europe 

 and the Atlantic Islands, and from North and Central America ; they
