76 BRITISH BEES. 



Finland. In southern Europe the genus inhabits Si- 

 cily, Spain, the Moreaj Albania, and Dalmatia, and is 

 also very abundant in Southern Russia. In Africa it is 

 found in Nubia and Algeria, and on its north-western 

 edge in Barbary, whence it descends by the Gambia and 

 Sierra Leone to the Cape of Good Hope, and thence 

 reaches to Natal. It is then found in Chili, and cross- 

 ing the South American continent occurs in the Brazils, 

 whence it ascends to Cayenne, and, by way of Mexico, 

 to the United States. The number of species recorded 

 exceed a hundred. 



The remarkable genus Chelostoma is very limited in 

 the numbers of its species, of which less than a dozen 

 are known; as also in the extent of their distribution. 

 Our own are found throughout northern Europe, as far 

 as Lapland, and in Russia. In southern Europe they 

 occur in the Morea, and the genus has been discovered 

 in Georgia in North America. 



The closely-allied genus Heriades seems limited to a 

 European habitation, and occurs only in our own soli- 

 tary species, but it ranges, like the preceding, to the high 

 latitudes of Lapland. 



Amthocopa seems limited to our own country and 

 Prance, possibly only from its having been associated 

 from similarity of general habit with the genus Osmia. 

 Only one species appears to be known, but this has a 

 world- wide celebrity, from the interesting account given 

 by Reaumur, of its hanging its abode with symmetrical 

 cuttings from the petals of the poppy. 



The genus Osmia, although not including such able 

 artisans as Megachile, still has in its species very con- 

 structive propensities. Indeed, all the bees which con- 

 vey the pollen on the under side of the abdomep, are
