From Dr. Bailey of Albany, I now receive a ? exactly agreeing 

 with my specimen, and I have also seen other examples in the 

 collection of Messrs. Neumoegen and Mead. I therefore offer 

 a description under the above name. Compared with A. auson- 

 iedcs, Bois. of which it is possibly a variety — it has the apices 

 more rounded, and the wings, both primaries and secondaries, 

 broader, though the average size of the insect is a little less. The 

 broken patch at the apex of the fore wings, is, in the present 

 form, deep velvety black, flecked with greenish scales, while in 

 A. aiisoniedes it is olivaceous, with yellowish scales. The patch is 

 also more compact, less divided by the white ground color of the 

 wings, the apex being therefore almost wholly black, with the 

 exception of a roundish spot, costally, and a couple of dashes mar- 

 ginally, of the white ground color. On the under side, the mar- 

 bled pattern of the secondaries is more extended over the whole 

 surface of the wing, thus more closely approaching the design of 

 A. Crensa, and A. Hyantis. 



The present form appears to bear the same relations to A. 

 aiisoniedes that A. Belia does to A. aiisonia of Europe. The speci- 

 mens I have examined (4^3 ?) were all taken in Colorado.

Entirely of a dark fawn color, with a leaden tint on the up- 

 per surface, and a blackish cloud at the base of primaries, as in 

 the var. galactinns. The markings of the under side are invisible, 

 when viewed from above. Beneath, dull brown, with a reddish 

 tint on the discal region of'the primaries, the markings very indis- 

 tinct, being lost in the prevailing dark color.

Most of the California species of il/<?/2V<;ert: are prone to extreme 

 variations, and none more so than the most beautiful of all, J/. 

 cJialcedon. I have before me examples of a form, however, which 

 is so remote from the typical specimens, and so constant in its 

 characters, as to deserve a name. I have desired to link with it 

 the memory of an esteemed friend, now passed away, viz: Mr. 

 Herman Dwindle, one of the most promising young entomolo- 

 gists of the Pacific coast, whose early death was a loss to science. 

 The specimens of this butterfly were taken by Mr. Dwinelle at 

 the McCloud fishing station, Shasta Co., Cal., and it is worthy of 

 remark, that no examples of Chalcedon agreeing with the form 

 common throughout the valleys of California, were found among 

 the insects taken in the above locality. My examples are 4^.3? 



Primaries very much suffused with red, which color predom- 

 inates over the discal portion, and toward the apices, almost ob- 

 scuring the usual white spots, or rendering them a sordid, dull
