countries all over the globe; but many of these are more abun- 
dant in the Palrearctic region than elsewhere. Such are Scarites, 
Calosoma, Brachimis , Cymindis, Lebici, Chlcsnius, Platynus, Bar- 
pains, Bembecidium , Pcecilus, and Argutor. Of tropical cosmopo- 
lites, or genera found in all the tropical regions, but not in the 
temperate zones, there seem to be only four, — Catascopus, Cop- 
todera, Colop odes, and Cactmonia. Pheropsophus is confined to the 
tropics of the Old World ; while Brimostoma , though widely 
scattered, is characteristic of the Southern Hemisphere. 
The Palrearctic region has about 50 genera of Carabidre which 
are strictly confined to it, the most important being, — Leistus 
(30 sp.), Procerus (5 sp.), Procrustes, (17 sp.), Zabrics (60 sp.), 
Pristom/chus (42 sp.), and Ophonus (60 sp.) ; but it possesses a 
large number in common with the Xe arctic region. The more 
remarkable of these are, — Carabvs, Nebria , Am am, Cyrtonotus, 
Brady cellvs, Anopthalmus, Celia, Cychrus, Pair obits , Blaphrus, 
Notiophilus, Bradytus, Callisthenics, Blethisa, and several others. 
Many too, though not strictly confined to the North Temperate 
regions, are very abundant there, with a few species isolated in 
remote countries, or widely scattered, often in an eccentric man- 
ner. Among these may be mentioned, Trechus (120 sp.), all 
North Temperate but 8, which are scattered in Java, New Cale- 
donia and South America ; Dyschirus (127 sp.), North Temperate, 
with 3 or 4 species in Australia, China and La Plata ; Omciseus, 
(88 sp.), S ter opus (90 sp.), Platysoma (114 sp.), and Pterostichus 
(138 sp.), are mostly North Temperate, but each has a few 
species in the South Temperate zone, New Zealand, Australia, 
Chili, and the Cape of Good Hope. Bromius (54 sp.), is about 
two-thirds Pal rear c tic, the rest of the species being scattered over 
the world, in Chili, North and Soutn America, South Africa, 
Burmah, Ceylon, and New Zealand. The North Temperate 
genera Calathus and Olisthopus, have each one species in New 
Zealand ; Percies has most of its species in South Europe, but 3 
in Australia; Abax is confined to the north temperate zone, 
but with one species in Madagascar while Lcemcsthenes is said 
to have a species identically the same in South Europe and 
Chili. Some of these apparent anomalies may Le due to wrong
