here. The yeUow secondaries will at ouce distinguish it, as no other 

 American species is so marked. 



The form found here, is said to be the Asiatic chardlnyi. Mr. Grote 

 first stated that the fore tibi;e in his specimens were spiuose, but 1 have 

 never been able to discover any. 



The bibliography so far as refers to our fauna, is —

Primaries varying in tint from reddish to dusky ocher brown with 

 the transverse lines blackish, eveu, tolerably distinct ; the t. p. line 

 with a rounded outward extension opposite the cell and a slight out- 

 ward tooth on vein one. Ordiuary spots sometimes distinctly limited. 

 Orbicular very oblique, attaining or fusing with thereniform interiorly, 

 pale with indistinct darker interior shades. Reniform upright, moder- 

 ate, with darker center and pale ochery ringed. The median space is 

 shaded with blackish posteriorly. S. t. line distinct and continued, 

 preceded by a dark costal shade relieving two costal pale dots. Ter- 

 minal line even, fringes dark. Hind wings yellow, with yellow fringes, 

 and a very broad black margin which intrudes more or less on the cen- 

 tral yellow field. Beneath the hind wings are yellow with narrower 

 black hind border and faint discal point ; costal region dusky. Fore 

 wiugs with the center blackish, costal and terminal regions brownish, 

 varying in tone with the upper surface. The body colors vary in tone 

 with the fore wings, and the black margins of the hind wings var^^ in 

 width, sometimes encroaching strongly on the yellow discal field. 



Expanse 26-34""". 1.05-1 .35 inches. 



Habitat. — Auticosti, Labrador, Maine, New York (Adirondacks), 

 Canada, Vermont. 



The above description is principally from Mr. Grote's characteriza- 

 tion of gilvij)ennis, which is very fair. There is considerable variation 

 in the ground color, and in the relative distinctness of the markings, 

 and also in the distinctness and size of the white costal spots. The 

 genitalia of the male are very simple, the harpes with the tip rounded, 

 not spinulose. The clasper consists of a long, very strongly curved, 

 corneous hook, shown in figure 1 on PI. ii. 



1 have taken this species in the Adirondacks at an elevation of about 

 2,000 feet, and also in Bennington County, Vermont. It seems not rare
