a short median dash of black. The costa is also marked with about eight small 

 clusters of black scales irregularly spaced. The inner margin is strongly dentate by 

 four clusters of long scales, whitish at base and tipped with black; the largest cluster 

 at inner third, the outer three evenly spaced within the middle third ; a small black 

 spot between two brown shades, on median line at outer two thirds and another black 

 spot on outer margin just below apex. Cilia pale fuscous, more than the width of 

 wing, on outer margin long wing scales project into cilia forming a smoky line bounded 

 inwardly by ground color and outwardly by pale fuscous and extreme edge beyond 

 that smoky fuscous, at apex the cilia is uniformly dark, forming a hook-like termi- 

 nation to wing. Underside dull fuscous. Hindwing, upper- and underside bright 

 silvery fuscous. Cilia very long, three to four times wings' width. Abdomen and 

 legs fuscous, latter banded with very dark brown. Alar expanse 13 to 14.5 mm.

Larva. — Mature 6.5 mm., robust, cylindrical, slightly tapering, width i mm. 

 Width head .6 mm. Head very pale brown, clypeus evenly triangular, reaching 

 nearly to vertex; slightly bilobed, lobes full and rounded. Mouth parts dark 

 brown, antennse moderate, pale green, except outer joint brown. Ocelli on black 

 field. Prothoracic shield, all of dorsal region, bisected by a narrow yellowish line, 

 same color as tubercular plates. Anal shield small, narrow, not chitinous. Thoracic 

 feet black, greenish-yellow at articulations. Abdominal feet normal, hooks very dark 

 brown in complete circles, not open. Skin creamy white, broad subdorsal band of 

 a smoky brown or pale grayish-brown from segment 3 to anal segment, involving 

 tubercles i and ii. These bands are continuous from 5, and on 3 and 4 are inter- 

 rupted between tubercular plates. The latter on thorax and abdomen are large and 

 same color as subdorsal bands, but a shade darker. Tubercles i and ii normal, iii 

 dorsad and cephalad to spiracle iv -(- v. On thorax ia -j- ib, iia -\- iib, iv -|- v. 

 Setae moderate, very dark nearly black. Spiracles small, round, very dark brown. 



/"?</«. —Nearly cylindrical to ends of wing cases, then evenly tapering to apex. 

 Length 5 to 6 mm. ; diameter i mm. Cremaster long, narrow, armed with about a 

 dozen short hairs, each terminating in a strong recurved hook, all pointing backwards. 

 Vertex of head full, rounded, smooth, and much paler in color than balance of 

 pupa, eye cases small, rounded, labrura small, labial palpi widens to double width of 

 labrum at one third below it, and extends down two thirds length of wing-covers. 

 Antennse and wing cases cover seventh abdominal segment, organs on frontal piece 

 well defined, sutures deep. A lateral spine on abdominal segments 4 to 7. Color of 

 pupa, except vertex of head, very dark brown, nearly black on dorsum. Dehiscence : 

 A long separation between antennal cases and labial palpi, on each side of latter and 

 extending two thirds their length ; labrum and clypeal piece remain attached to 

 labial palpi ; half of eye cap attached to wing cover. Antennae remain cemented 

 to wing covers on lateral edges.
