or angular and slightly or deeply serrate. Hind wings extending as far as the 

 tip of the abdomen, full and large, either scarcely bent, and with a slight sinus, 

 or distinctly angulated, with a single deep sinus, or regularly and deeply den- 

 tate. Venation: costal vein either free (hypochraria) or anastomosing with 

 the subcostal (bilinearia and serratarid). No subcostal cell, or else a cell is 

 nearly completed by the close approximation of the second subcostal venule 

 to the main vein. In hypochraria, the first and second subcostal venules of 

 the same length; in the other species, the second is very long. The posterior 

 discal venule is more or less oblique. Hind legs with the tibiae much swollen ; 

 the tarsi from three-fourths to one-half as long as the tibiae. Abdomen rather 

 long and slender, well tutted. Coloration : different shades of ochreous- 

 brown, with the extradiscal line common to both wings, and often split asun- 

 der in the middle of the wing, inclosing a lanceolate oval area: usually with a 

 white or dark oblique apical spot or streak. 



The species of this large and variable genus may usually be distinguished 

 by the falcate and often deeply serrate wings, the large palpi, and the 

 thick, swollen, hind tibiae. Where the wings are not serrated, they have a 

 large angle in the middle of the outer edge, often preceded by a deep sinus. 

 The females have more deeply serrate and broader wings than -the males. 



Synopsis of the Species. 



A. Wings short, not falcate, entire ; body hairy : 



Ash-reddish-brown above; common extradiscal line sinuous; beneath reddish- 



ochreous E. pilosaria. 



B. Wings subfalcate ; hind wings sinuous, but not notched : 



Paler ash than usual; common extradiscal line nearly straight; beneath washed 



with ochreous E. apitiaria. 



Eust-brown ; extradiscal line reddish, very sinuous, but not angular E. duaria. 



Ash-brown, with a violet tinge ; extradiscal line bfint at right angles E. hypochraria. 



C. Fore wings more falcate than before ; hind wings notched near 



the apex : 



A large species, pale ash-brown ; a submarginal row of light irregular spots; outer 



half of both wings darker than the iuner E. marginata. 



Uniform fawn-brown, with reddish lines and fringe : do teeth near the apex of the 



hind wings; extradiscal lines straight ; an apical light patch E. vinulentaria. 



Hind wings tailed : not dentate oi sinuous as usual ; reddish-brown and subochre- 



ous : unit i led irregularly : extradiscal line sinuous E. textrinaria. 



In form like vinulentaria, but toothed near the apex ; wings whitish within, fawn- 

 brown mi the outer two-thirds ; a subapical light patch E. madusaria. 



Deep ochreous ; margin of the wings reddish-brown ; hind wings with a deep angu- 

 lar notch : a subapical light patch, with an oblique row of smaller spots, - . E. amamaria.
