SATYRUS II., III. 



varied .somewhat in the shade of green, being more or les.s yellow, in .some, j'el- 

 low prevailing on dorsum, green on the sides. They varied also in the clothing 

 ol" the surface, some being covered witli sliort (h)\vn, others witli rather long 

 and appressed hairs. There was no constant character l)y which Mcjjhelc could be 

 distinguished irom AIo2)e, but the Ncplidc-Ohimpus differed perceptibly from the 

 others. They were long and slender, and deep yellow-green with distinct side 

 stripe. 



The chrysalids of AJcrpe and Catskill Nephele were alike in color, yellow-green. 

 The female chrysalids were clouded with darker green, and the edges of head 

 and wing cases were cream color. The Olipnpns chrysalids were blue-green, 

 lighter or darker, and the edgings were white. They also could be readily dis- 

 tinguished. 



One chrysalis of Albany Alope gave a male butterfly without band, but with 

 a narrow yellow niud)iis about the ocelli, — an intergrade. One chrysalis of Cats- 

 kill jVtpJiL'h' gave a typical female Alope, with broad yellow band, but the wings 

 were darker than in southern examples. This is figured in Plate II., o, 4. The 

 Coalburgli chrysalids produced typical Alope butterflies, all of them. Two Olym- 

 pus gave males of their own type. In 1877, a female butterfly which emerged 

 from the Catskill chrysalis before spoken of, was an intergrade. 



Therefore, south of the belt of dimorphism, Alope produced Alope, but inside 

 the belt, Alo'pe produced intergrade, and Nephele produced Alope and also an in- 

 tergrade. And ISfephele-Ohiiiijius, again, outside the belt, produced its kind. 

 That Nephele, north of the belt, breeds true is certain, because the intergrades 

 and Alop>e are not found there. 



I believe AlojJe to have originated in the southern form Pegala Fab., which is 

 characterized by its large size, its broad rufous band, and single ocellus on fore 

 wing, and by six ocelli in both sexes on under hind wing ; ami I regret that I 

 am not able to properly figure this form in connection with Alope. I cannot do 

 so, because I know nothing of the i)reparatory stages, though by the kindness of 

 the late Dr. (). C. Sparrow and of Mr. W. H. Ashmead, of Jacksonville, Florida, 

 repeated attempts to obtain the eggs have been made, but all without success. 

 So far the females have refused to lay when confined with grass. Perhaps before 

 this Volume closes I may yet succeed. Pegala is restricted to the vicinity of 

 the Gulf of Mexico and a strip along the Atlantic coast, at least as far to the 

 north as Charleston, South Carolina ; but does not appear at Indian River, Florida, 

 nor, as far as observed by Mr. Mead and others, in the interior of that State. 

 It seems to be mainly a coast species. I cannot learn that Pegala and Alop)e fly 

 in the same localities or even in the same districts. There appears to be a lielt 

 in the cotton States, or from Georgia to Mississippi at least, in which Alope is
