to live on the surface or underground. The following tabular 
view of the proposed arrangement is given by Schiodte (/. c, 
p. 143) 
I. Eyes finely granulated, naked. Middle coxae distant . . Oxytelus. 
riatystethus. 
II. Eyes coarsely granulated, hairy. Coxae approximate. 
1. No antennal grooves. 
a. Legs organized for rooting ; anterior tibiae with only 1 row of 
spines, emarginate at apex ; lateral costa of elytra close to mar- 
gin Haploderus^ 
h. Cursorial legsj tibiae with fine hairs, entire ; lateral costa of elytra 
far from margin Carpalimus. 
2. Antennal grooves in front of eyes. Legs fossorialj anterior tibiae 
entire, with a double row of spines; lateral costa distant from 
margin Blcdius, 
The old genus Bledius thus characterized is divided by Schiodte 
into five genera, two of which are characterized as new. These 
are tabulated as follows (/. c. pp. 144-145) : — 
I. Apical portion of mandibles thick, with a strong sharp tooth (with other 
characters). 
A. Anterior acetabula open without ; lobes of ligula with 3 elongated 
branches, profusely subdivided, the innermost very long ; spinulose 
ridges of anterior tibice distant Bledius^ s. str. 
[Danish sp. : — B. tricomis (Herbst), hicornis (Ahr.), and a new 
species.] 
B. Anterior acetabula closed ; lobes of ligula with only 1, long, much 
subdivided branch; spinulose ridges of anterior tibice approxi- 
mate TadunuSj g. n. 
II. Terminal part of mandibles attenuated ; lobes of ligula hinged on the 
outside (with other characters). 
A. Inner lobe of maxilla spinulose, terminal spines strong, blunt ; lobes of 
ligula rounded, spines lobate at their points. Bargus^ g. n. 
B. Inner lobe of maxillae not spinose ; lobes of ligula elongate, pointed. 
a. Anterior acetabula open externally; apical portion of mandibles with 
1 tooth ; mentum deeply bifid ; spines of ligula serrate. 
Astyeops (Thoms.). 
[Danish species : — A. talpa (Gyll.) and subtei'raneus (Erichs.).] 
h. Anterior acetabula closed; apical portion of mandibles with 2 
teeth; anterior margin of mentum straight; spines of ligula 
blunted Ilesperophilus (Steph.). 
[Danish sp. : — II. arenarius (Payk.)].

Danish species are also briefly described : — Bledius^ p. 145 ; Astyeops^ p. 149 ;
