as Lapland ; it also crosses the Atlantic, being found in 

 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 Portiigal 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
