GENUS CALEPHELIS 203 



The sexes of Zela are very much aHke, and one figure will 

 sufficiently illustrate the species, especially as this Arizona form 

 has but slight interest for us in the coast region. 



300. Lemonias Cleis.

 tains, 1903 ; Stephens. 

 This also is a mountain form from the Arizona mountains. It 

 seems to be a Mexican form, just happening in American terri- 

 tory, as it is not known from any other locality than southern 

 Arizona. 



Genus CALEPHELIS. 



A most charming group of very small butterflies, all of them 

 distinguished by having two rows of plumbeous spots, like dull 

 silver, on both sides of both wings, but most plainly seen on the 

 under side. Two species are eastern, one of them coming west to 

 California, and two are western, going eastward only to Arizona 

 and Texas. 



301. Calephelis Borealis. 



Plate XXVII; Figure 301, Female, Lake County, Cal., 

 June, 1894 ; Author. 

 This example here figured was taken by the author in Central 

 California, as noted, and it is the only one ever mentioned as 

 captured west of Illinois. Presumably it is invading the West 

 Coast, as some other species have done, and may in a few years 

 become common. This specimen was taken in the mountains at 

 an estimated elevation of 3,000 feet. 



302. Calephelis Australis.

 Australis and the next. Nemesis, are much alike ; Australis is 

 the darker, and smaller, and generally marked by a dark band or 

 curved shading across the middle of both wings, with the basal 

 part darker than the marginal. I have found Australis more 

 plentiful at Yuma than at any other point, although it is occa- 

 sionally taken all over southern California. The dark fringes on
