90 THE ENTOMOLOGIST. 



a specific name, yet his intention was clearly to base the genus 

 on Hiibner's species, and not to introduce a different one. 



Finally, the name Rhyacionia has sixty-two years' established 

 use as based on the type hastana, which is after all in accordance 

 with Hiibner's specification, and Stephens' intention, as ex- 

 plained above. It might be deemed incredible that anyone 

 would offer to cause so much confusion on such flimsy grounds. 

 Even if the change were made, the discovery of a casual mention 

 of Rhyacionia hastana in any publication of earlier date would 

 suffice to reverse the whole procedure.
