The peculiar shape of the reniform and the conical abdomen, as 

 well as its smaller size, will at once distinguish this species from the 

 three allied to it.

Crermana {)wv. s]).). 



Habitus and markings of soHdaginis, hat differing in the following respects : 

 Base of the antennae concolorous instead of white. Legs, breast and collar 

 colored with brown. Costa on the median and subterminal spaces distinctly 

 tinged with brown. The orbicular spot geminate, consisting of two equal, 

 concolorous white wings. The reniform very distinct, rounded, outwardly 

 excavated with a central white curved spot, surrounded by a dark shade — 

 the whole enclosed within a clear fine white annulus. The median lines are 

 nearly obsolete. The exterior line only evident opposite to the reniform ; 

 there it forms long, acute teeth on the nervules. The median shade consolid- 

 ated into one broad, black, even, outwardly curved band, and not diffused 

 throughout the median space as in solidaginis. Subterminal line and the two 

 preceding dashes as in the allied species. Posterior wings uniform, dark 

 fuscous, without median line ; beneath whitish, also without line, but with a 

 strong discal dot. 



Had., Adirondack Mountains. (Mr. Bowditch.) The strongest 

 distinctive characters of our form are found in the shape of the 

 reniform, and in the different shape and importance of the median 

 lines.
