The border is composed of two parts, the inner black, the outer a black'brown, crenate line on each side of which it is a little paler. The black on the hind wing supports a row of violet lunules. Underside dark brown with the usual wavy lines and spots; the outer half yellowish brown with a submarginal of gray blue lunules which are black edged. LarvaâThe mature larva is a little more than an inch long, with a black head sprinkled with minute whitish dots, from which spring pale Iiairs. The body is nearly black above, with small white dots and pale hairs, which give it a grayish color. The spines are arranged as in antiopa, and are black and branching. It has a greenish yellow lateral line above which is a bro^ken line of brighter orange yellow shade. The larvae are found on the wild nettle, and there are two broods in a season. ChrysalisâThe chrysalis is .8 of an inch long, 20 mm., slightly angu- lar, the frontal beaks short, conoidal; thoracis projection forming nearly a right angle; dorsal spines but little elevated. DistributionâIt ranges from the mountains of West Virginia north- ward to Nova Scotia and Newfoundland, thence westward to the Pacific. This tortoise-shell butterfly is one of the first harbingers of spring. Uusually it is the first butterfly seen about Missoula, where it is rather common. It is usually quite abundant around the biological laboratory at Flathead Lake, but in the summer of 1903 but very few were seen. Brandegee has collected it at Helena, and Wiley reports it rare at Miles City. At Swan Lake it is occasionally seen, pr
