Tliis connnon and easily reco<rnized species dillers Ironi all the others 

 of the genus l)y the white; ground color of the Ijody and wiiiir>;. It seems to 

 be common in the Northeastern Slates. It is easily divided info two forms: 

 u^ small, and with short wings, the Tcplnos'ui notd/arhi of Walker and 

 F. (itiadripiuir/iifd of .Morrison ; and, h, Jidnnhita, a form with lona' winiis, the 

 outer edge not bent, rather long, and the win^s less heavilv l>aud<'d and 

 spotted with l)rown ; !)ut there are iiulividnals liefoic me w liich dill'er in these 

 respects, and indicate two interesting races, which show signs of intermingling. 

 It should also Ite observed that T have taken iioth I'aces in the same field 

 and on the same days. In the markings, it varies much as do all the specic^s 

 of tiie genus. In some s|)ecimens of variety Jidoiiiala (.Alinol's lucolaraiia) 

 there are no bands, and the wings beneath are free fiom large spots and 

 l)ands, with only scattered brownish scales. Sometimes, on each side of the 

 discal spot on the fore wings, there is a dark brown line much deeper in toiu> 

 than the brown shade which it limits. Karelw the hind w'mn is densely 

 mottled with brown. The four large, round, eciual, discal dots are always 

 distinct, and farther separate the species from its allies.
