On the other side of Africa the genus has been discovered 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 southern 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 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 _Andrenidæ_. Our own single species of these very elegant bees occurs throughout France and Germany, and abounds in Sweden. Other species, all elegant, 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 appearance and structure of the terminal genus of the preceding subfamily of _Andrenidæ_, it is strictly distinct, and well links the two subfamilies 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, Germany, 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 and marked to have caught the eye. It is as lithe and active as a Malay, as black as a negro, and as hairy as a gorilla, looking like a little ursine sweep. The genus EUCERA, of which we have but one representative, although considerably more than fifty species are known, has not so wide a range as might be expected from their numbers. Our own is found throughout Europe and in Algeria. Other species occur in Russia, the Morea, Albania, Dalmatia, and Egypt. In Asia some are found in Syria, and at Bagdad; and from the New World they have been sent from Cayenne and the United States.
