typical specimens appear to be very distiuct; a good many authors, however, consider 

 thein to be merely varieties of one species. 



Z:. nanus, Scliauni. {minimus, Chaucl. ; gihhuJiis, Mots.). A very 

 minute species, the smallest of the European Scydmjcnidre ; of a rather 

 long convex form, clothed "with line and rather thick pubescence, which 

 is thicker and somewhat bristl}^ at the sides of thorax, brownish-red, or 

 pitchy, or reddish-testaceous (the colour of the head and thorax being 

 sometimes darker than that of elytra) with the legs and antenna) yellow ; 

 head somewhat round, narrower than thorax, antennae rather stout, with 

 a three-jointed club, the two penultimate joints transverse ; thorax some- 

 what cylindrical, a little narrower than elytra, impunctate, with four 

 fovese at base of which the inner pair are large, and the outer small and 

 indistinct; elytra oval and convex, very finely punctured, impressed at 

 base, L. | mm. ^ 



Under decaying leaves, &c. ; extremely local ; I know of no other locality except 

 Scarborougli, iu the nei:;hbourhood of which place it has been taken iu some numbers 

 by Messrs. Lawson and Wilkinson. 



EUMICEINA. 



The members of this tribe resemble the Scydrnj^nina in general 

 appearance, but agree with the Cephenniina in the formation of the 

 maxillary palpi ; they are rather closely allied to the Mastigina, a tribe 

 Avhich contains some of the largest representatives of the Scydmainidse ; 

 in fact this tribe is by some authors included under -the Eumicrina ; 

 the Eumicrina are represented in Britain by one genus containing two 

 species, which dilTer from one another in several important points, and 

 have in consequence been placed by some authorities in difl'erent 

 genera. 



EUMZCRUS, Castelnau. 



This genus contains a considerable number of species which are found 

 in various parts of the world, representatives having been recorded from 

 Korth and South America, India, Australia, Arabia, &c. ; they occur in 

 moss, vegetable refuse, hot-beds, &c., and also in damp wood mould 

 under bark. 



T. Elytra and thora.K with more or less distinct basal impres- 

 sions or foveaj ; eyes large ; anterior tarsi strongly dilated 

 in male ; size larger; colour pitchy-reddish or castaueous . E. TAuSATtrs, MiiU. 



II. Elytra without basal impressions, thorax without distinct 

 fovejB ; eyes small ; anterior tarsi simple in both se.xes ; size 

 smaller; colour rufo-testaceous E. eufus, Milll. 



E. tarsatus, Midi. Chestnut-broAvn or pitchy-red, head and thorax 

 often darker, antennae and legs red ; form rather long, convex, narrowed 

 in front ; upper surface clothed rather sparingly with yellowish pubes-
