GEOGRAPHY OF THE GENERA. 69 



fairly surmised, they are so very like our own that one is 

 said to be absolutely identical throughout Europe and in 

 Ohio. It passes still forward and occurs in Nova Scotia, 

 Hudson's Bay, and elsewhere in arctic America, where 

 the botanist might almost herbalize through the agency 

 of our insects, for the pollen they carry and still retain 

 in cabinets would often indicate the plants which they 

 there frequent. Thus those stern regions are not barren 

 in fragrant and attractive beauties. We find it, too, in 

 common with Sphecodes at Sydney, New South Wales, 

 whence, doubtless, it passed to New Zealand, where it 

 has been collected. About one hundred and fifty are 

 registered. 



With the next genus, DASYPODA, I terminate the 

 geography of the Andrenida. Our own single species 

 of these very elegant bees occurs throughout France and 

 Germany, and abounds in Sweden. Other species, all ele- 

 gant, occur in the Isles of Greece, in Albania, and the 

 Morea; profusely at Malaga in Spain, and at the further 

 extremity of northern Africa in Tunis, and in Egypt. 

 Twenty are known. 



The genus PANURGUS is the advanced guard of the 

 true bees, for, although it still retains much of the ap- 

 pearance and structure of the terminal genus of the pre- 

 ceding sub-family of Andrenida, it is strictly distinct, 

 and well links the two sub-families together. This very 

 peculiar form is limited in number of species and in 

 distribution, for five only have been recorded. 



Our own species occur throughout France, Italy, Ger- 

 many, Switzerland, Denmark, Sweden, and Finland, 

 and one of them has also been sent from Oran. The 

 genus is small, and may have been overlooked in other 

 countries, although its appearance is sufficiently distinct
