A REVISION OF THE DELTOID MOTHS SMITH. 69 



spicnous at the inner margin. Orbiculiir marked as a small, (;lear 

 yellow spot, which is sometimes lost. Keuiform upright, narrow, some- 

 what constricted centrally, yellow, with a black dot at each extremity. 

 Secondaries ])aler, but rather more smoky, with a distiiu-t dusky extra 

 median line continuous witli the transverse posterior of primaries, 

 and a pale subterminal line continuous with that of the primaries, 

 and sometimes marked by <larker sha(lin<;s, an<l, indeed, as a rule the 

 wings darken outwardly, relieving the line somewhat. A series of 

 black terminal dots, sometimes forming an interrupted terminal line. 

 Beneath with ocherous powderings; all wings with a discal mark, a 

 brown extra median, a pale subterminal and a blackish terminal line, 

 the latter interrupted and somewhat punctiform. 



Expanse of wings, L'O to o2 mm. = 0.80 to 1.25 inches. 



Habitat. — Eastern, Middle, and Central States; Georgia, Alabama, 

 Colorado. 



The essential characters of the species have been pointed out in the 

 introductory remarks. The male seems to have the power of expand- 

 ing in every direction the ])alpal tuft. The palpi of the female are nor- 

 mal and quite, long. In this sex the tendency is to a more reddish 

 ground color and less evident maculatiou. In a small male from Georgia 

 the reniform is prominently black and the other markings are reduced 

 and punctiform. 



The other sexual characters of anteunic and forelegs agree with those 

 of the genus.
