from a friend about a year ago. I've read that this is a
difficult genus to identify to very many species so, I am
requesting that someone help me with (possible) species
identifications on these 4 specimens.
The information written on the envelopes is shown. That
is all that I have on them. Several other envelopes had
(RCA) on them so, I am presuming most of the lot came
from there. Unfortunately, these were the only surviving
(good) specimens as all others were lost to booklice
damage.
