CARABID.E. 19 



The B. maurus, so abundant throughout Europe, is widely spread 

 over these Atlantic islands where, indeed, most probably it is uni- 

 versal. As yet, however, it has been observed only in Madeira proper, 

 Porto Santo, and the Deserta Grande, of the Madeiran Group, and 

 in Grand Canary, Teneriffe, and Palma, of the Canaries.

The B. plagiatus of central and southern Europe is, like the last 

 species, widely spread over these Atlantic Groups. It is certainly, 

 however, scarcer than the B. maurus at any rate in the Madeiran 

 archipelago, whence two examples collected by the late Mr. Bewicke 

 in Porto Santo are all that I have yet seen. But at the Canaries 

 it is far more common, and may perhaps be universal; though 

 hitherto it does not happen to have been observed in either Palma 

 or Hierro. In the other five islands, however, although local, it is 

 not by any means rare.

The M. patruelis, which is widely spread over Mediterranean lati- 

 tudes, occurs in at any rate the eastern parts both of the Madeiran 

 and Canarian archipelagos particularly in arid, sandy, and calca- 

 reous spots. It abounds in Porto Santo, and is found on the Ponta 

 de Sao Lourengo (the eastern promontory) of Madeira proper ; whilst 

 at the Canarian Group it has been observed hitherto only in Lanza- 

 rote and Fuerteventura.
