description of slight or intangible variations that would 

 make it impossible for students to unravel their author's 

 meaning. 



Leilia is a pretty form or variety. The types were two 

 males taken by Mr. Henshaw, of Lieutenant Wheeler's Ex- 

 ploring Expedition, August, 1874, at Camp Lowell and in the 

 Sonoto Valley, Arizona. It is well figured in the " Butter- 

 flies of North America," 2, pi. 1. The figure in Dr. Hol- 

 land's Butterfly Book is more properly the Arizona form of 

 antonia, at least from a nomenclatorial standpoint (PI. 23, 

 fig, 11). Our series of leilia are from Sonora and Arizona, 

 taken in 1883 by Morrison. Three specimens like Dr. Hol- 

 land's figure of leilia were taken at Mt. Graham by Morrison 

 in 1882. 



The types of alicia were from New Orleans, Louisiana. 

 All our specimens are from Florida, and those that bear any 

 more than a State label were taken by Dr. Wittfeld at Geor- 

 giana on the Indian River. 



Celtis occurs in the southern half of the United States, east 

 of the Great Plains. Riley says the butterflies appear in 

 eastern Missouri by the middle of June, and that there is a 

 second brood in August. In West Virginia they appear the 

 end of May (Edwards). It has been recorded from as far 

 north as Massachusetts. In New Mexico it is replaced by 

 antonia and leilia. Our series of specimens are from Ken- 

 tucky, Tennessee and Texas. The Tennessee specimens 

 were taken at Nashville, June 13th to 24th, and the Texan 

 examples at Black Jack Springs, July 19th 



The clyton group is not so complicated and the forms or 

 varieties are fewer. The figure of the species given by Bois- 

 duval and Le Conte is a rather poor one, the coloring being 

 rather crude. The figure given by Mr. Edwards under the 

 name var. ocellaia in his Butterflies of North America, 2, I 

 consider to represent the species and may be taken as typical 

 clyton. I do not see any reason for the name ocellata he 

 gives it. Variety proserpina Scudder has the hind wings 

 much darker and the maculation almost obscured. This is 

 well illustrated on the same plate (figs. 5, 6). Strecker in
