 $ . — Head orange, yellow on vertex. Palpi black ; antennae black 

 Prothorax yellow with two large black spots. Patagia black edged with 

 yellow, very narrowly so on the inside. Thorax black, with two broad 

 yellow stripes ; abdomen blackish, the segments edged with white 

 along the sides and beneath. Legs black ; coxce of the anterior 

 pair, orange ; all the tibiae whitish outwardly. All the thoracic parts 

 smooth. 



Anterior wings velvety black ; fringes white. Veins clothed with 

 yellowish scales. A very broad, irregular, sub-basal transverse band, 

 widened on the inner margin to a narrow marginal stripe. The usual 

 longitudinal stripe below the median vein, furcate on the outer margin. 

 A narrow transverse band originates on this longitudinal stripe, and 

 runs across the origin of the 4th median nervule, nearly to the costa. 

 From the same point, a second band runs across the origin of the 

 median nervules, parallel with the outer margin, towards the costa, 

 but terminates on the subcostal vein. The usual terminal band 

 springs from band 2 on the median nervules, the lower fork uniting 

 with the upper branch of the longitudinal stripe, while the other runs 

 towards the apex but is reflexed sharply towards the costa before reach- 

 ing it. 



Secondaries thinly scaled, dark cinereous, fringes white ; below the 

 median vein is a broad whitish stripe, breaking into three forks near 

 the outer margin. A second similarly colored stripe, originates at the 

 origin of the median nervules running towards outer margin in two 

 branches. These markings are somewhat badly defined. 



Beneath the primaries reproduce the black markings, but the ground 

 color is dirty white, with the basal half of the costa yellowish. The 

 secondaries are largely white, the blackish covering of the upper sur- 

 face being confined to broken spots along costa and outer margin. 



Expanse of wings, 1.35 inches ; length of body, 0.60 inch,. 



Habiiat. — Labrador, (Moeschler, Strecker). Mt. Washington, New 

 Hampshire, (Sanborn). 



A. Quenselii czxi. be mistaken for no other American Arctian. It is 

 abundantly separated by its peculiar grey aud white secondaries. The 

 yellow markings on the primaries are somewhat broken and less regu- 

 lar than in many other species. A. gelida, Mceschler, is given as a 

 synonym on the authority of that author himself, my friend, Mr.
