This species may be known by the angular falcate fore wings, with the 

 tight reddish-brown lines on the pale ash-speckled wings, and by the dentate 

 hind wings, with the single clear line and submarginal abbreviated line, as 

 well as by the short small palpi and elongated hind wings projecting farther 

 than usual beyond the body. This species is allied to M. celiaria Walk from 

 Florida, which may prove to be a variety of the present species. 



This agrees well with Guenee's description, except that the edge of both 

 wings are clear in all my specimens. 



Larva — "Caterpillar of a very pale green, with th'e sutures and sides 

 reddislya double angle {arete) bordered with reddish on the second ridge, 

 another more salient on the sixth, and finally another on the tenth ; the fifth 

 lias on each side a small pointed tubercle. Head and feet concolorous. It 

 lives on the oak and poplar, in April; it pupates at the beginning of May, 

 and the moth appears at the end of the same month. The chrysalis is of a 

 gray-brownish, with the abdominal incisions reddish."' — (Guene'e's descrip- 

 tion from Abbot's MS. drawings.)
