next come to the tribe Cara- 
bides, consisting of the follow- 
ing genera : — Pelophila, Neboia, 
Metrius, Leistus , Procerus, Procrustes, 
Cardbus, Aplothorax, Calosoma, Cal- 
listlienes. 
Pelophila consists of some insects 
bearing a superficial resemblance to 
Blethisa, and closely allied to Nebria. 
They inhabit Northern Europe and 
Siberia. Some live on the borders 
of streams, like Blethisa-, others 
under stones, like the majority of 
the genus Nebria. The species being 
closely allied, entomologists differ as 
to their number.” 
Nebria is a large genus, “ consist- 
ing of more than 80 species.” They 
occur in almost every variety of 
situation, “ some even being found on 
the loftiest cliffs, in the neighbour- 
hood of eternal snow. They were 
long supposed to be confined to Eu- 
rope, Asia, Northern Africa, and 
North America, but one species has 
lately been discovered, among the 
Himalayas, and another in Ota- 
heite.” 
Metrius consists of a single Cali- 
fornian species, which lives under 
stones and fallen trees, and appears 
to be rare. 
Leistus consists of nearly twenty 
species, “ with one exception (Jerrn - 
gineous, which occurs on the north- 
west of America), confined to Europe 
and Northern Asia.” Their habits 
are known to most English cole- 
opterists. 
Procerus contains eleven species, 
of a beautiful blue or green color, 
one or two, however, being black. 
Its metropolis is a district “ extend- 
ing from Eastern Europe to the re- 
gions round the Caucasus, and in- 
cluding Asia Minor, Persia, and 
Egypt.” The genus is closely allied 
to Cardbus. 
Procrustes consists of about fifteen 
species allied to Cardbus. Their 
habitat is Southern Europe, W estern 
Asia, and Northern Africa. One 
(coryaceous) is very common in 
Western Europe. 
Carabus M. Lacordaire calls “ one 
of the most beautiful genera in the 
family, and one of the richest in 
species.” There appear to be be- 
tween three and four hundred species 
known. They are spread over al-
