Extract

Having lately received from Mr. Friese, of Innsbruck, a number of European bees, I have been led to re-examine certain of our species, in order to determine their relationship to a number of old-world genera not supposed to occur in America. The result is extremely interesting, and seems to show that we have for many years been placing bees in genera to which they by no meaos belong. The following table may be used provisionally to separate the genera under discussion:

A. Tongue more or less short and broad, tapering at the end. (Andreninæ).

* Mr. Friese send me also four examples of Nomioides pulchellus, Schenck, taken at Pest on the second of June. This bee is a Perdita with the venation of an Halictus! It is curious to see all the ornaments, aculpture, etc., of Perdita, with a long tapering marginal cell and three submarginals. It is evident from this, and from the absence of Perdita in the American tropics, that our genus is of boreal origin, not austral, as I formerly thought.
