12. Platyptilia AURIGA n. sp. PI. XLIV, fig. 2. 



General color gray, with a very slight brownish tinge. Scales of head and 

 thorax with paler bases, thorax whitish behind. Antennae spotted above. 

 Frontal tuft short, conical; palpi rather long, oblique, slender. Fore and mid 

 tibiae black-striped, tarsi with slight dark shades on one side. Hind legs grayish 

 with darker bands, three distal tarsal joints mostly whitish. Abdomen with 

 diverging light and dark stripes above, sometimes obscured (stained?) except 

 in posterior margins of segments, and parallel stripes below. 



Primaries dull dark gray, variably, usually slightly, irrorate with white 

 scales. Cleft preceded by a transverse black dash which forms the outer margin 

 of an imperfectly developed triangular patch reaching the costa but fading 

 out basad. Cleft outlined with blackish in its basal half. Both lobes with 

 blackish dashes reaching the outer pale line, which is more or less incomplete. 

 Dashes sometimes obscured in a general dark shade. Fringes white, gray 

 tipped, with black basal scales on outer margin. Apices and anal angles with 

 gray fringes, inner margin with several scale teeth and scattered black scales. 

 Secondaries and their fringes concolorous with primaries. Fringes of inner 

 margin of third feather with pale bases containing numerous black scales and a 

 somewhat triangular tooth just before apex. Expanse about 18 mm.

In addition to the types we have a single broken specimen from 

 Montclair, N. J- 



The early stages are unknown. 



This species resembles dark specimens of edzvardsii and is not 

 unlike the female which we are calling zvilliamsii Grin., but the form 

 and position of the black scale-tooth alone suffice to distinguish it. 

 The markings of the abdomen are useful in good specimens. The 

 male genitalia resemble those of Carolina (see plate L, fig. 15).
