 quisquiliis prjecipue in inferioribus fodiens. 



A European Psammodius which is widely but sparingly distri- 

 buted over these islands, occurring beneath refuse principally at low 

 altitudes. It has been taken in Madeira proper and Porto Santo, of 

 the Madeiran Group, and in Lanzarote and Grand Canary, at the 

 Canaries.

 haud observatus), sub lapidibus quisquiliisque pra3sertim in 

 arenosis submaritimis fodiens. 



The P. sabulosus of Mediterranean latitudes is probably universal 

 (or nearly so) throughout these Atlantic islands, occurring princi- 

 pally in low and sandy spots towards the coast. At the Madeiran 

 Group it has been taken sparingly in Madeira proper (by the Barao 

 do Castello de Paiva, the late M. Eousset, &c.) and commonly in 

 Porto Santo, and at the Canaries in all the seven islands except 

 Palma where it does not happen to have been observed, but where 

 nevertheless it must doubtless exist.
