I am Roy-Keith Smith, an Assistant Professor of Chemistry at Southern College of
 Technology, 1100 South Marietta Parkway, Marietta, GA 30135.  Most  of my resea
rch to date has dealt with analysis of cuticular hydrocarbons (particularly the
unsaturated fractions) of honey bees.  I have recently begun a project with Wm S
tephen, Oregon State University to characterize the Megachilids of the United St
ates and the Mediterranean Basin.  I have already looked at M. apicalis and M. r
otundata from the West Coast and Western Canada and find a rich diversity of uns
aturated compounds to be present.  These compounds can identify not only the spe
cies but also the sex.  As part of the project we are interested in examining ot
her specimens of these two species, and others, from across the USA and Canada.
 The methodology involves immersion of the pinned or loose individual bee in hex
ane for extraction of the hydrocarbons.  The insect remains intact and can be re
turned whole to the persons making loans.  If you are interested contact me at B
ITNET RSMITH6@SCTNVE or call me at 404-528-7316.
