immaculate iorms^fulricofitu and ve.stalifi, which are abundantly distinct 

 from each other, though tliey may possibly be albino forms of one or 

 the other of the maculate species. J do not believe this, however, and 

 prefer for the present to consider them distinct, though perhaps uot 

 strongly nuirked, species. 



An examination of the genital structure proved my idea correct, suf- 

 ficient constant dilfereuces existing to make the distinction certain if 

 not very great. 



The scheme of the arrangement in synoptic; form is as follows:
