THE GENUS CATOCALA. 



BY G. H. FRENCH, CARBONDALE, ILL. 



It is 16 years since the Rev. G. D. Hulst undertook a revision of 

 this genus along the lines of " Structural Characters." As a new Check 

 List of the moths is to be published soon, it seems proper that another 

 arrangement of the genus be made. The structure of the genitalia as a 

 basis of the separation of the species has been regarded by many eminent 

 lepidopterists as of doubtful value. It is certain that in this genus' its use 

 was not warranted by larval characters or field observation. For these 

 reasons the last revision has not been satisfactory to those who were 

 familiar with many species in their native haunts, or who had bred them. 

 The writer does not say, however, that the present revision will be fault- 

 less, for as yet too i^w of the species ere known in their adolescent stages
