III. Catalogue of the Zygaenidae of North America. 



Since the publication in tlie " List," of the Xorth American 

 Zygaenidae in 1868, by the late Coleman T. Robinson and myself, 

 several new forms have been described by Dr. A. S. Packard, Jr., 

 and Mr. Richard H. Stretch. lu the valuable work of the latter 

 Author, now appearing in Parts, are also several suggestions in rela- 

 tion to the synonymy of certain species, Avhich I here adopt. In 

 the Fourth Annual Report of the Trustees of the Peabody Academy 

 of Science, Dr. Packard suggests that Eupsychoma geometrica, 

 Grote, from Colorado, is the same or ratlier a variety of Nemeophila 

 petrosa, Walker. I have described and figured two species of 

 Nemeophila from California, and also examined Mr. Walker's types 

 of the genus in the British Museum. My type of Eupsychoma is in 

 the collection of the American Entomological Society, and I did not 

 have it with me in 1867 for comparison when in London. It differs 

 from Mr. Walker's type and description by the immaculate second- 

 aries, and it is broader winged. Dr. Packard's remarks show me, 

 however, that I have probably erroneously referred the species to 

 the present family in 1865, and it is here excluded. From wliat 

 we already know of the distribution of this Family, we may expect 

 the discovery of many more species from Southern California, 

 the South-western Territories and Texas. In my Notes on the 

 Zygaenidae of Cuba, 1866, I have drawn comparison between the 

 profusional intertropical representation of the Family and this 

 limited number, both of genera and species which appear as inhab- 

 itants of the Atlantic District, where the Bombycidae are the pre- 

 vailing element. In the present " Catalogue " all species not 

 occurring within the Faunal limits embraced by Dr. Le Conte's 

 List of the Coleoptera are omitted.
