as the first four equally short joints together, claws robust. 



The one European species lives on the sea-shore under seaweed and 



stones or in cracks of stones where it often is washed over by the tide 



waters.

black, finely haired, dully glistening; antennal base and legs pitch- 

 brown. 



The surface of the body very finely shagreened, the head's forehead 

 foveae feeble, its dorsal side together with pronotum with fine and scat- 

 tered punctation, the latter oftem smooth at middle-line; elytra with 

 scattered, feeble scabrous punctation; abdomen with fine and scattered ; 

 punctation. L. 2.5-3 mm. 



In the S 1 the foremost dorsal abdominal joint at base with two distinct 

 small fovea, (accd. to Janglb. and Thorns.). 



It is found at the coasts of northern France, England, Norway and 

 western Sweden in company with Poduridae and Acaridae , in crevices of the 

 rocks, under stones and seaweed. In Denmark it is heretofore not found 

 but i.C not improbable that it may be discovered at the coast of the North 

 Sea or in the yet hardly explored islands in Kattegat. - The larva is 

 described by Laboulbene (Ann. Soc. Ent. France 1858). - J. Schiddte in 

 Nat. Tidsskr. 1844-45 describes a ireenlandish species, M. brevillngue 

 Schio. The larva of this is found at the Museum at Copenhagen.
