152 THE CANADIAN ENTOMOLOGIST. 



has named halcyotie, and these differ most obviously from the local speci- 

 mens in being paler in both colour and basal shading above, and lighter in 

 markings. As to my former references to coronis, Behr., under this heading, 

 Dr. Skinner tells me that the types of that species came from Mare's 

 Island, San Francisco, now built over or otherwise spoilt entomologically. 

 Also that Mr. Edwards's identification of the species was erroneous, and 

 that the types having now been destroyed in the San Francisco fire, the 

 exact identity of the species is doubtful. I took a pair in cop. at Brisco, 

 B. C, on the Upper Columbia, about thirty-five miles below Windermere, 

 on July 15th of last year, which are probably the same as the Calgary 

 species. The male, however, is washed with green beneath rather than 

 brown, and I at first mistook it for Meadii or JVevadefisis, but it agrees 

 best with \\\q plat'ma-halcyotie series in other respects. It reflects brown 

 in certain lights, which Calgary Meadii do not, and nearly all of the local 

 series show a green iridescence as well as the brown, suggesting that the 

 colour is prismatic rather than pigmentary. Another ^ , taken at the same 

 place and time, is also greener than any Calgary specimens. The varia- 

 tion leads me to suspect that this species may, in some localities, 

 sometimes be confused with Nevadensis or Meadii. 



9. A. Nevade7isis^ Edw., var. Meadii^ Edw. — In my list I recorded 

 this species as JVevadefisis merely, but have now decided that Meadii fits 

 it better. I have compared it with four male and five female Edwardsii 

 from various Colorado localities, three male Nevadensis from Nevada, 

 Nevada Co., Calif, and Yellowstone Park, Wyo., and with four male and 

 three female Meadii^ one pair from Stockton, Utah, and the rest from 

 Colorado. My Edwardsii are quite the largest of the group, and com- 

 pared with the local form are rather darker, though having less of the 

 dark basal shading above, the veins with less black, and in the females a 

 heavier black border. Beneath there is more and richer red on primaries, 

 and the very much darker green on secondaries (Holland says "olive- 

 brown ") encroaches much more on the buff submarginal band, so as to 

 sometimes almost obliterate it, and the marginal silver spots differ in 

 shape. In the Calgary species they are almost triangular, pyramidal, with 

 the vertices generally rather sharply angled, almost dentate. In my 

 Edwardsii they are more nearly rounded, with the vertices blunt. A 

 single specimen from the Red Deer River, though pretty obviously 

 conspecific with the rest of my series, bears some resemblance to 

 Edivardsii in the shape of the spots and partial obliteration of the band.
