the United States. About six are known. 
Our solitary species of the genus Macropis, which 
is isolated possibly only from having been overlooked, 
appears to have but a European existence, and is 
found in France, Germany, Denmark, Sweden, and Fin¬ 
land. 
The genus Halictus is very cosmopolitan. Some of 
our own species occur throughout Europe, excepting 
only Italy and Sicily, although they are to be found 
in Portugal and Dalmatia, thus traversing its entire 
breadth; but from the latter country they do not seem 
to range down to Albania and Greece, yet are they 
discovered in Malta, and even in southern Africa, but 
they have not been recorded as extant in northern por¬ 
tions of that continent. Other species have been sent 
from the western coast of Africa and the adjacent Cana¬ 
ries, with their adjunct, Madeira, and the genus ranges 
from Barbary through Senegal and Sierra Leone; some 
species also are found at the Cape of Good Hope. 
On the other side of Africa the genus has been dis¬ 
covered at the Isle of Bourbon; it then takes a wide 
sweep, occurring first in northern India; it then springs 
up at Foo-chow-foo, and it is found in northern China. 
In western Asia it occurs in Syria. Across the Pacific 
it is found in Chili. Its next appearance on the rich 
and diversified continent of America is across its south¬ 
ern bulk, presenting itself in the Brazils, and on its 
northern boundary at Cayenne, and in Columbia; and 
it then appears again in Jamaica. In North America 
it occurs throughout the United States from Florida 
upwards, where the genus in its species has a very 
English aspect, and if they be dissimilar, as may be
