species. The chief peculiarity in the venation of primaries is the incep- 

 tion of vein 5. A comparison of the figures on plate xiii will at once 

 illustrate. 



The legs are short, densely clothed with hair; the middle and hind 

 tibia with short terminal spurs. The wings are short, stout, and rather 

 broad, giving the insects rather a heavy appearance. Besides the 

 characters enumerated, the species agree in typical maculation of sec- 

 ondaries. The disc is yellow, outwardly margined by a black line, at 

 base usually more or less pink or reddish. The outer margin is some- 

 what variable in color, usually very near to that of primaries, and there 

 is always a reddish or brown line or band through its center. In the 

 yellow disc is a large black ocellus with a linear white pupil, and blue 

 irrorations around it. 



Four species are described from the United States. lo, the most 

 common species, found everywhere in the Eastern United States, is 

 readily distinguished from all its allies by the irregular subterminal 

 line, which is as far from the apex as from the hind angle. The typical 

 form is yellow, with the markings red brown, while the var. lilitli is 

 suffused with reddish, and in the 9 the yellow is replaced by a ferrug- 

 inous red. 



The other species have the apex of primaries much more produced, 

 and there is an excavation to the outer margin, making them slightly 

 falcate. 



Zelleri is the largest of the species, with smoky, luteous brown prima- 

 ries in the 9 , the transverse anterior line irregular and distinct; the 

 t. p. line is even, nearer to apex than to hind angle — a characteristic 

 shared also by the following species, they having the line still closer 

 to the apex : 



Pamina and zephyria lack the t. a. line entirely, or it is very indistinct. 

 In pamina the primaries are bright pale-clay yellow, the t. p. line dusky, 

 with a yellow preceding shade; in zephyria the primaries are gray and 

 the line is white, and more than usually oblique. The variety aurosea 

 bears to pamina the same relation that the var. lilith does to to. It is 

 the form with a reddish suffusion. 



In tabular form, the scheme above set out appears as follows : 



T. p. line irregular, wavy, as far from apex as from bind angle.
