man, it would not be difficult to recognize this sj)ceies from its near- 

 est California relations bj the greenish hue of the under side 

 of the hind wings ; for there is no green about any of the Califor- 

 nia species. 



In Morris's Catalogue of North American Lepidoj)tora, there arc 

 now six species very closely related amongst themselves, but deci- 

 dedly distmct. Most of them have been described, and only one 

 or two are new. Of course it is very difficult to recognize the spe- 

 cies from a mere diagnosis, and even the diagnoses of Boisduval, 

 being interspersed here and there into the Annales de V Entomohgic 

 are not altogether within my reach. I have therefore adopted the 

 plan to give the characteristics of the species, without a name, but to 

 add a figure and leave it to others that are in a better position for 

 researches, to add the name. 



Their names are Zerene, Mormonia, Hydaspe, Egleis, Adiaste. 

 Amongst these, for instance, the diagnosis that Dr. Boisduval gives 

 of Zerene, certainly comprises two species, of which one seems to 

 be not yet known in Europe. All those species a[)proach, in their 

 markings, nearest to the Eurojjean T. Adippe, and A. 2\iohe, but 

 differ constantly by the want of the series of eye spots that is 

 always found in either species between the marginal lunulae and 

 middle fascia of the hind wings. 



4. A. Adippe similis, sed alac posticae serie ocellorum inter 

 maculas marginales fasciamque mediam destitntae. Maculae cunctae 

 argenteiB marginales tri<|uetrae, fasciae intermediii.e quadrangulares.

This and the following species are not so intensely colored on 

 the upper side as most of the related species are, and the colora- 

 tion of the female partakes even a little of that of A. Calippe. Under 

 side of the hind wings reddish-brown, with a few diluted spots ; 

 from the intermediate fascia to the margin, straw-colored ; and the 

 intermediate fascia also towards the margin bordered by buff color. 



This species is found high up in the mountains. 



6. A. Adippe similis, sed alae posticae serie ocellorum inter 

 lunulas marginales fasciamque intemediam destitntae Macu- 

 lae marginales certe argenteie, reli(juae pruina (juadam metallica 

 obductae ; marginales semilunarcs, fasciae iutermediae ovales, rad- 

 icem versus nigro raarginatae. 



This species is found in different localities, but always ui moun- 

 tainous regions. It is much more common than No. 4, and easily 

 recognized by the black bordering of the spots of the intermediate 

 fascia, their oval, not quadrangular shape, and the rounded form of 

 the marginal spots.
