'^08 WM. H. EDWARDS. 



Under side of primaries pale fulvous, inclining to yellow on the 

 eosta and hind margin ; an irregular black patch on middle of costa. 

 another near apex, a third within the inner angle and a fourth on mid- 

 dle of inner margin ; a few indistinct lines near base caused by the 

 transparency of the wing; apex yellow and a yellow patch on middle of 

 hind margin ; a marginal series of fine crenated brown lines, a second 

 beyond that, distinct only at the apex. 



Secondaries purple-grey (or pearly-grey in some specimens) over 

 rather more than the basal third and broadly along hind margin, leav- 

 ing between a submarginal band limited on either side by a delicate 

 crenated brown line that crosses the entire wing ; this band is yellowish, 

 clouded at the costal edge and in the middle by brown ; a row of spots 

 or points along the middle of the band, corresponding to the spots of 

 upper sui'face, obsolete at outer exti'emity ; hind margin bordered by a 

 fine brown crenated line, above which is a second, (which is the outer 

 edge of the submarginal band) the spaces between the two being lunu- 

 lar; at anal angle the purple shade gives place to yellowish; the mid- 

 dle crescents clouded by the brown shade that obscures the band ; 

 the basal portion of the wing reticulated with fine brown lines where- 

 of the outer ones being most regular form a second band across the 

 wing ; next the .base the lines are irregularly placed ; towards costa 

 and about the base the purple shade a little replaced with yellowish. 



Body above black, covered with fulvous hairs; below white; palpi 

 white; antennse black above, whitish below; annulated with white; 

 club black above, fulvous below. 



Female. 1.7 inch; a shade paler than the rnale ; similarly marked. 



Found from New York to Louisiana, and hitherto considered as a 

 variety of Tharos, from which it is readily distinguishable by the pur- 

 ple or pearly hue of the under side of secondaries. Tharos is one of 

 our many species about which much confusion has existed, several dis- 

 tinct forms being by various authors considered to be included within 

 the limits of this species. In 1864 I separated M. Phaon^ {Proc. Eiit. 

 Soc. Phila.,) and Mr. Reakirt has since described Batesii. To this 

 may be added 3Iarcia, above described. 



Boisduval and Leconte in Lep. d' Amer. page 170, regard Tharos 

 of Cramer, pi. 169, and Tharos of Drury, Vol. 1, pi. 20, as identical 

 and describe and figure what they consider the type. The figure of 

 the male and the description correspond, viz : "the under side (^of sec- 

 ondaries) is of an ochrey-yellow with a great number of undulating 

 ferruginous lines, a brown border that reaches neither angle, marked
