In order to substantiate my present view, I propose to give a 

 brief account of all the descriptions we have of H. chrysanthellum, 

 together with a short description of the specimens which have 

 passed under my notice. This will, I hope, have the further 

 effect of putting other naturalists on their guard, and of tending 

 to give some idea as to the specific characters of this form.
