1 have formed this genus to include the species which 

 I formerly placed as a separate section (B) of the genus 

 Botys ; I suggested at the time the possibility of this 

 course, and it now seems desirable. The characters of 

 Botys, as given by me, must of course be altered by 

 striking out the words " or all long and equal."
