Apart from its brightly rufescent elytra and rufo-testaceous limbs, 

 this singular Bledius may readily be known by the immensely elon- 

 gated, narrow, acicular, glabrous, and porrect horn with which the 

 prothorax of its males is armed in the centre of the anterior margin. 

 In the opposite sex the prothorax is quite simple ; but in both (though 

 more particularly the male) the head is furnished on either side (at 

 the insertion of the antenna3) Avith an oblong tubercle. Like the last 

 species, it is extremely rare, and confined (so far as I have observed 

 hitherto) to the sandy shores (and salt places generally) in Lanzarote 

 and Fuerteventura. In the foraier I took it sparingly both at the 

 Salinas (or salt-works) in the north of the island and on the beach 

 to the south of Arrecife ; whilst in the latter I met "nith it, beneath 

 marine rejectamenta, about a mile to the south of Puerto do Cabras.

In the greatly-produced, narrow, and acute process with which the 

 anterior margin of its male pronotum is armed this Bledius belongs 

 to the same type as the jjreceding one ; nevertheless the prothoracic 

 horn of the B. galeatus is not quite so elongated (seeing that it does 

 not extend beyond the extreme outline of the head), and it is also 

 differently shaped — being graduaUy narrowed from the base to the
