This species is quite usually confused with Z. ohscuripennis or even Z. 

 cruralis, diftering from both by t'>e angulated transverse anterior line 

 of the i)rimaries. I have only five si^ecimens before me, ficnn as many 

 localities, indicating rather an uncommon form. Of these, four are 

 luteous, like the types in the British Museum, and differ only in the 

 relative i)romineuce of the reniform; while one specimen without 

 definite locality, but probably from Long Island, JSf. Y., is of a very 

 decided purplish brown, with a strongly contrasting subterminal line. 

 It is i)ossible that we have to do here with a different s]>ecies, but the 

 material is not Mifficient to decide the question. As has been indicated, 

 the types of Z. jii'otxmnosalis and Z. iiiiinnialis are of tlu' luteous form. 



In the male characters this sjiecies is ^•ery like Z. ohscuripennis, 

 especiall}' in the antenna', in which three joints are quite generally 

 furnished with corneous processes, the third or ui)per decidedly smaller 

 than the others.

Ground color luteous, M'ith fine, even, ocherous powderings. Head 

 and thorax concolorous. Primaries with the median lines very slender, 

 tending to obsolescence. Basal line wanting. Transverse anterior 

 line quite evenly outcnrved and with moderate oiiteurves in the inter- 

 spaces. Transverse posterior line irregularly bisinnate, with moderate 

 denticnlations on the veins. Sul)terminal line ])ale, rigid, not defined 

 by <lark lines or shades. A series of venular black terminal dots or 

 lunules. Secondaries paler than the primaries, with a very feebly 

 marked, dusky, extra median line, and a more distinct, pale subtenninal 

 line. An iiiterru])ted brown terminal line. Beneath ])ale, luteous 

 gray, with ocherous ])owderings. ^Vll wings with a discal spot, a brown 

 extra median and a pale subterminal line, and all variably evident, 

 sometimes nearly obsolete.
