do not yet know the clirysalis, nor the natural food plant selected by the 

 insect, nor just how the winter is passed. The habits of the butterfly 

 need more attention, and particularly its distribution, which is the more 

 important, from its being our northernmost type of skippers.

Imago (58:7). Head large, furnished with short scales and heavy, transverse 

 masses of long hairs; at the exterior base of the antennae a moderately long, spread- 

 ing tuft of curving bristles, directed forwards and outwards, the length equalling 

 about one-third of the semi-circumference of the eye. Front considerably tumid, 

 considerably and roundly elevated in advance, so as to bring nearly the whole front 

 almost to the level of the vertex, and hence surpassing considerably the front of the 

 eyes; the sides beyond the inner margin of the antennae scarcely partake of this 

 tumidity and are separated from the middle portion by a distinct, slightly sinuate 

 sulcation ; fully twice as broad as long, separated from the vertex by a straight, trans- 

 verse snlcation, slightly in advance of the middle of the antennae; the middle por- 

 tion of the front border scarcely concave, laterally well rounded off and forming with 

 the sides a regular curve to the outer margin of the antennae. Vertex a little tumid, 

 elevated considerably and regularly above the level of the eyes, transversely flat in 

 the middle three-fourths, nearly twice as broad as the frout, separated from the occi- 

 put by a scarcely perceptible, brace-like mark. Eyes large, pretty full, naked, 

 more broadly rounded behind than in front. Antennae inserted with the hinder 

 edge of the base in the middle of the summit, their interior bases separated by 

 more than twice the diameter of the basal joints, the whole antenna somewhat longer 

 than the abdomen, composed of thirty-three to thirty-five joints, of which nineteen 

 form the club, which is more than one-third of the antenna, and is bent beyond the 

 middle of the outer half, at the nei.'hborhood of the twenty -fourth joint; it increases 

 in size up to the twenty-first joint, where it is fully eijual in width to the length of two 

 joints ; from here it tapers regularly and rapidly to a point, the twenty-ninth joint 

 being equal in diameter to the slender stalk ; the club is subtriquetral, slightly com- 

 pressed, the crook bent at right angles backward; the joints at the middle of the 

 stem are about three and one-half times longer than broad. I'alpi rather stout, a little 

 more than tNviceas long as the eye, the basal two joints very heavily clothed with long,
