100 THE CANADIAN ENTOMOLOGIST. 



Under surface bluish green, with a darker patch on last two segments; feet 

 whitish, semi-transparent ; prolegs bluish-green. 



The change to chrysalis took place June 19th. Length of chrysalis 

 0-35 in. ; widest on anterior portion of seventh segment. Head case round- 

 ed. Body dark reddish-brown with black markings, thickly covered with fine 

 short whitish hairs, most numerous on anterior and posterior segments; ante- 

 rior segments with many thickly set patches of blackish; a dark ventral line 

 from sixth to twelfth segments. 



This larva very closely resembles that of Acadica. 



Lycœna negledcx, Edwds. — Larva found feeding on Dogwood (^Cornus — ?) 

 July 12th. Fed it afterwards on willow, which it readily ate. 



Length 0.45 in., somewhat onisciform, distinctly annulated. Head small, 

 dark shining brown, with a black streak down the middle, widening as it 

 approaches the mandibles ;. mandibles brown, with a streak of a paler color 

 above across them ; head drawn within the second segment when at rest. 



Body above dull greenish-white with a faint tinge of yellow; second 

 segment has a deeper shade of green, with a blackish line across its posterior 

 edge where it joins the third segment; a dorsal line of a slightly darker 

 brownish shade; a dull green band across anterior portion of fifth segment, 

 and another in the same position on eleventh; on each side of each segment, 

 from fifth to eleventh, is a spot of the same hue extending obliquely back- 

 backward. Dorsal crest of a whiter shade than the other portions of body ; 

 sides of body slope abruptly, widening considerably at the base. Entire 

 upper surface covered with minute dots from which^arise very short fine 

 hairs, invisible without a magnifyer, but giving the surface a downy appear- 

 ance. Twelfth and thirteenth segments much flattened. 



Under surface similar in color to upper, with the satne downy look ; feet 

 faintly brown ; prolegs partake of the general color. 



A very young specimen was decidedly yellow, with the darker markings 

 scarcely apparent. A second pale green, with scarcely any markings. A 

 third about the same size of a much deeper green, strongly marked with dark 

 green as in the full grown specimens, but more distinct. 



The chrysalis I failed to note, also the duration of the pupa stage. 



Hesperia — . Larva, probably Thanaos, found feeding on hazel, July 31. 



Head large, dull red, slightly bilobed, each lobe pointed above^and tipped 

 with reddish-orange; a spot of the same hue just above mandibles, and 

 another midway between these, forming a row of three on the outer edge of 

 each side of the head. 



Body above dull whitish-green, covered with minute dots of a whitish or 

 greyish-white color ; a lateral stripe of pale yellow or whitish yellow, becom-
