possible two drawings of the genital stipites of each species were made, an outline 

 drawing of the dorsal aspect of the pair of stipites and a more careful drawing of a 

 single one of the same individual, the stipes being shifted so that the view falls ver- 

 tically upon its broad expanse. Drawings of a single stipes of a species are of the more 

 careful kind. In a few cases stipites of several indi-\dduals of one species are figured 

 to show variation.
