THE CANADIAN ENTOMOLOGIST. 00 



No.' 3, Leto, he says " the diagnosis that Dr. Boisduval gives of Zonae 

 certainly comprises two species." Giving to one of these the name 

 Monticola, he leaves Zerene Bois. to the other. The former he charac- 

 terizes by the under side of its hind wings being deep brown, approaching 

 violet, the latter being cinnamon-colored. All this I set forth in my paper 

 of 1864. before referred to. In 1869, Dr. Boisduval, without apparent 

 knowledge of what had been done in the matter in this country, in his 

 Lep. de la Cal., applied the name Hydaspe to what Behr had specified as 

 Zerene, using these explanatory words : " This Argynnis, of which we have 

 seen very few individuals, perhaps may be a local variety of that which 

 we have before described under the name of Zerene. It is a little 

 smaller, its wings, are more rounded at summit ; the under side of the hind 

 wings is less vinous, with the yellow spots more clear colored and dis- 

 tinct. Besides this, the female has the marginal spots always yellow, like 

 the others, and never silvered as in the female of Zerene." I have the 

 type specimen of the male of Hydaspe, sent me by Dr. Boisduval, labelled 

 and marked " type." It is cinnamon-colored and Behr's Zerene. The 

 Zerene figured in But. N. A. has the under side of hind wings ferruginous, 

 but in all other respects agrees with Behr's description and type, and 

 was sent me by Dr. Behr as Zerene. The cinnamon-colored form I was 

 unacquainted with till several years after my Plate was published, when I 

 received it under the name of purpurascens, H. Edw., var. Edw. But. N. 

 A., VI. pi. 32. In this series of examples from Nevada, embracing more 

 than 100, taken by Messrs. Mead and Morrison, the ground color of 

 hind wings varies from bright to dull cinnamon, ferruginous and brown. 

 Some are buff overlaid with diluted ferruginous, including the belt be- 

 tween the two outer rows of. spots, here and there the sub-color appearing ; 

 some have this belt clear buff and the rest of the wing mottled with a 

 vinous gray. In some the cinnamon or ferruginous largely covers the 

 disk, in others very slightly. Some have the under side of hind wings 

 largely melanized. So with the silvering ; some show the spots as clear 

 buff, some buff with a few scales of silver. Of Zerene, I have found no 

 male with all spots silvered beyond these few scales, though sometimes 

 the marginal row is moderately silvered. The female varies in same man- 

 ner, but some examples show more silvering, while others have not a trace 

 of it. The typical Monticola of Behr is figured in my Vol. 1, pi. 27, and 

 appears in these Nevada examples, the ground being vinous-brown, mot- 

 tled with clear brown ; the male without silver. But while the females of
