22 MADEIRAN COLEOPTERA. 
The specimen from which the above description has been compiled 
is unique, as Madeiran, and is now in the British Museum. It was 
detected by myself amongst shingle at the edges of the stream in the 
Ribeira do Alcayde, between Feijaa d’Ovelha and Porto Moniz, on the 
6th of July 1855. It is a species of rather wide geographical range, 
being recorded in France, Switzerland, the Tyrol, and Algeria; and 
I have seen an example which was captured by E. Armitage, Esq., 
in Turkey. 
63. Bembidium bistriatum. 
Elaphrus bistriatus (Meg.), Dufts., Fna Austr. ii. 205 (1812). 
Tachys minutissimus (Leach), Steph., Ill. Brit. Ent. ii. 7 (1829). 
Bembidium bistriatum, Dej., Spec. des Col. v. 42 (1881). 
, Woll., Ins. Mad. 73 (1854). 


Inhabits Madeira proper, occurring amongst moss on the wet ledges 
of the rocks, and by the small trickling streams, at rather low and 
intermediate elevations. 
64, Bembidium curvimanum. 
Bembidium curvimanum, Woll., Ins. Mad. 74. tab. ii. f. 6 (1854). 
Inhabits Madeira and Porto Santo,—being rare in the former 
(where I have only taken it at the Lamuceiras and at the mouth of 
the Ribeira da Janella stream), but rather common in the eastern 
ravines of the latter. Sometimes the rufescent patches of the elytra 
(especially the humeral ones) are obsolete, under which cireum- 
stances it should be regarded as a distinct variety,—the var. /3. 
65. Bembidium Lucasii. 
Bembidium Lucasii, Duval, Ann. de la Soc. Ent. de France (2itme 
série), x. 187 (1852). 
, Woll., Ins. Mad. 75 (1854). 


Inhabits Madeira proper, occurring at low and intermediate eleva- 
tions,—from the gardens of Funchal to about 2000 feet above the 
sea. 
66. Bembidium obtusum. 
Bembidium obtusum, Stwrm, Deutsch. Fina, vi. 165 (1825). 
Tachys obtusus, Steph., Ill. Brit. Ent. ii. 6 (1829). 
' Bembidium obtusum, Dej., Spee. des Col. v. 177 (1831). 
, Woll., Ins. Mad. 75 (1854). 


Inhabits all the islands of the Madeira group, except the Northern 
Dezerta (on which at least it has not yet been detected),—ocecurring 
at all altitudes.
