EXPLANATION OF PLATES 



All figures, unless otherwise noted, are made from light prints of photographs direct 

 from the specimens, finished with India ink brush drawings. They are reproduced by 

 the heliotype process. Enlargements, if any, are indicated by an improper fraction placed 

 at the right lower corner of each figure; if not so distinguished the figure is of natural 

 size. All specimens, not otherwise noted, are in the author's collection.
