As I thought, our specimens all predate your 1950 cut-off. If you become interested in the more historical collections, please let me know.
Visitors are always welcome to come use the collections or loan needed specimens.
On a side note, please check your mailing database for names associated with the Academy. Ron Vasile is no longer with the museum. Dear Mary - Thank you for your reply. I am the sole individual working with all the Academy's collections. Genera you are interested in.
