STAPHYLINID^E. 



Likewise a Canarian Othius, and equally rare with the preceding 

 one, occurring in sylvan and subsylvan spots of intermediate and 

 lofty elevations. I have taken it in the district of El Monte i 

 Grand Canary, and it was found by the Messrs. Crotch in the Pin 

 above Ycod el Alto in Teneriffe.

Habitat Maderenses (Mad., P to S to ), rarissimum ; in locis subinfe- 

 rioribus, sive paululum elevatis, parcissime occurrens. 



Found at a rather low elevation in Madeira proper and Porto 

 Santo, but exceedingly rare. Indeed the only locality in the former 

 of those islands in which it has hitherto been observed is the neigh- 

 bourhood of the Cabo Garajao, or Brazen Head, about two miles to 

 the eastward of Funchal. I am very doubtful whether it is more 

 than a geographical phasis of the European A. depressum, from 

 which it seems to differ merely in its head, eyes, and antennae being 

 just appreciably more developed ; in the punctures of its head and 

 prothorax being perceptibly coarser ; and in its elytra being less 

 shining, of a more uniform rufo-piceous hue (being less dark in 

 front, and less pale posteriorly), and with their subasperated punc- 

 tures perhaps a little larger, but at the same time somewhat more 

 confused (or less sharply denned). 



1381. Achenium subcsecum. 



Achenium subcsecum, Woll, Cat. Can. Col. 581 (1864). 



Habitat Canarienses (Lanz.\ rarissimum ; sub lapide quodam in 

 montibus semel captum. 



The only example of this remarkable, and very pale, Canarian 

 Achenium which has yet come beneath my notice was taken by my- 

 self (from under a stone) on the mountains in the north of Lanzarote. 

 Its completely apterous body, much abbreviated elytra, and almost 

 obsolete eyes (which are so diminutive and punctiform as to be quite 

 imperceptible from above) give it a character peculiarly its own.
