for all of the updates!!!

I just submitted another one which seems to be also A. curta. Would appreciate your opinion:

where do I access those, probably spread over numerous publications?
Perhaps also in the Cockerell references given by Michener (2007).
Any suggestions?

Cockerell described many new species from specimens collected at Claremont by Baker in major publications such as:

1916. New and little known bees from California. Pomona Journal of Entomology and Zoology 8: 43-64.

All the bees described in this paper are from Clareont or the vicinity.

And in many other shorter papers such as:

1916. Some California bees. The Canadian Entomologist 48: 391-393.

Note that Baker material can now be found in several collections including the Cal. Academy.

Here is a very useful link:

You can download a biography of Cockerell and a complete list of the species he described.
