Euconnus.] CLAVICORNIA. 81 



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

 them to be merely varieties of one species. 



E. nanus, Schaura. (minimus, Chaud. ; gillulus, Mots.). A very 

 minute species, the smallest of the European Scydmaenid* ; of a rather 

 long convex form, clothed with fine and rather thick pubescence, which 

 is thicker and somewhat bristly 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, antenna? 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 

 Scarborough, in the neighbourhood of which place it has been taken in some numbers 

 by Messrs. Lawson and Wilkinson. 



EUMICRINA. 



The members of this tribe resemble the Scydmsenina 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 

 which contains some of the largest representatives of the Scydmoenidse ; 

 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 differ from one another in several important points, and 

 have in consequence been placed by some authorities in different 

 genera. 



EU1VIICRUS, Castelnau. 



This genus contains a considerable number of species which are found 

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

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

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

 tinder bark. 



I. Elytra and thorax with more or less distinct basal impres- 

 sions or f'oveae ; eyes large ; anterior tarsi strongly dilated 



in male ; size larger; colour pitchy-reddish or castaneous . E. TAUSATUS, Mull. 



II. Elytra without basal impressions, thorax without distinct 

 foveffi ; eyes small ; anterior tarsi simple in both sexes ; size 



smaller; colour rufo-testaceous E. ECFUS, Mull. 



E. tarsatus, Mull. Chestnut-brown 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- 

 cence ; head somewhat orbicular, antennae long with the first joint
