The female form hermodur occurs everywhere among the type, and can at most 

 be considered an aberration, and not, as Stiohel .says, a local race confined to South 

 Colorado. P. sa>ji is not even an aberration worth naming.

X. PARNASSIUS APOLLO (Linni;). 

 This species, the type of the genns, has been the subject of an enormous amount 

 of literature. It has been split up into no less than 31 subspecies, and below I am 

 describing two more. It is, however, a most regrettable fact that 17 names 

 have been given to mere individual aberrations. P. ajtol/o is one of the most 

 variable of butterflies, and it would be jjossible to name almost every second 

 specimen as a distinct aberration. If entomologists continue this ]iractice of 

 naming whole hosts of individual aberrations, it will make the scienlilic study of 

 insects of almost insurmountable difticulty, and also once again bring entomology 

 into the disrepute from whicli we were hoping it was gradually emerging.
