PTEROPHORUS KELLICOTTII. 

 Lioptilus Kellicottn~Fish, Can. Ent, Vol. XTIL, p. 141 (1881). 



Expanse of wings, 28-30 mm. Head ocbreous brown, whitish 

 between antennae. Palpi rather long and slender, second segment 

 with a small tuft of raised scales on the upper side at the extremity. 

 Antennae pale ochreous, brownish beneath ; thorax and abdomen 

 pale brownish ochreous, the latter striped longitudinally with pale 

 brown lines. Fore and middle legs brownish ochreous ; hind legs 

 whitish ochreous, tarsi paler. 



Fore wings pale ochreous, dusted more or less with brownish 

 scales, which in some examples form longitudinal streaks on the 

 costa and basal half of the median space; a dark- brown dot on 

 the base of fissure ; two brown dashes on the costa near the apex, 

 one on the hind margin of first lobe near the apex, usually four at 

 the end of the second lobe on veins 2, 3, 4 and 5. Fringes con- 

 colorous. Hind wings, also under side of all the wings, cinereous 

 brown, with a silky lustre. Fringes darker. 



Habitat. New York. Food, Solidago. 



" The larva, when first examined, August 22, was .3 of an inch 

 long ; color light yellow, head and shield darker, the oblique anal 

 plate almost black, bearing hairs and hooks ; dorsal and subdorsal 

 lines pinkish. By the middle of September it abandons the 

 branches, being then .45 of an inch in length, and bores into the 

 stalk a few inches above the ground ; it makes its way down 

 the pith into the roots, well under the ground, where it passes the 

 winter. I fetched several examples from the fields in January for 

 examination; they were then .58 to .6 of an inch in length, 

 lighter in color, with the longitudinal lines of pink brighter than in 

 autumn, the eighth segment conspicuously marked on the back by 

 pink. There are few hairs over their smooth bodies ; on the last 

 ring, however, there is a brown or black chitinous disc, with a 

 circle of long brown hairs about its circumference; in the centre 

 of this disc there is a small papilla, with two stout, straight black 

 teeth, pointing rearwards ; these teeth are hooked upward in the 

 autumn stage. The hairs render the plate sensitive to touch, and 

 help to brush fragments from their long, narrow galleries, while the 

 teeth assist in backward motion in them. The mature larvae ob- 

 tained in May differ but slighty from these, except that they 

 are then .7 of an inch long, and the pink stripes and marks are 

 brownish. The fourth, fifth and sixth segments are smaller than
