lines. Inner middle line marked on costa by a black dot ; below it is obsolete, or 

 partially indicated. A black discal dot near tlie costal spot of the inner line. Outer 

 line irregularly denticulate, better marked superiorly, where it runs obliquely out- 

 ward to median nervules, produced about vein 4, thence running inwardly below 

 vein 3, whence it descends, very slightly outwardly projected, to internal margin. 

 Terminal field wide ; a diffuse, broad, brownish or blackish shade-band marking the 

 veins. A terminal series of distinct interspaceal black marks becoming continuous 

 inferiorly. Fringes pale, interrupted with brown and with a dotted line. Hind 

 wings fuscous, the vems darker marked ; a discal dot vei;y near the base and costal 

 border ; a terminal distinct line ; fringes pale, with a dotted brown line. Beneath 

 yellowish-gray, sometimes suffused with blackish ; a common line and discal dots: 

 the terminal shade on fore wings less prominent than above, and here also continued 

 on secondaries. 



Venation. — Vein i of the primaries is almost always furcate near the base, the 

 furcation being sometimes merely a notch and sometimes extending as a vein to base. 

 4 and 5 generally join at base or are separate. On secondaries 7 and 8 are separate. 



The insect seems to be very widely distributed. It is taken in the 

 U. S. , east of the Rocky Mountains, and Lederer's specimens came from 

 Brazil. I have found the larva on RJius ioxicodendron and Rhus glabra. 

 It is tortriciform, marked on the segments with black dots. It folds over 

 the leaf or joins together the leaflets, and lives within the habitation thus 

 formed. It is almost without doubt 2-brooded.

Palpi heavy, erect, reaching above head, heavily ridge-scaled in front and thus 

 flattened in appearance. 3rd member rather fine, distinct ; maxillary palpi as in 

 siiperatalis, not quite so prominent. Palpi, maxillary palpi and head blackish gray. 

 Antennae strongly double bitufted in (^ — slightly so in O. Antennal process long, 

 reaching nearly to abdomen, closely scaled above, heavily clothed with long scales 

 and hairs below and at the end. Male antennal piocess as long as the thorax, or 

 nearly so. Male maxillary palpi scaled. Labial palpi a little exceeding the front, 

 curved upward, with the third joint shorter and more distinct than in Epipaschia. 

 Fore wings divided into three fields by the median lines. Inner line defining out- 

 wardly the blackish basal space. The line itself is black, with a slight median notch, 

 perpendicular. Median space washed anteriorly with white. A short, black, discal 

 streak. Outer black line very finely denticulate, shaped much as in siiperatalis, but 

 not produced so much on median nervules. It arises at about apical third, at first 

 outwardly oblique, then running inwardly below median vein and narrowing the 

 median space thence to internal margin. Terminally the wing is again black or 

 blackish. A broken black line at the margin. Fringes on l)0th wings dark, ]>ale at 

 base, with broken blackish interline. Beneath blackish, with common shade-band 

 and black discal point on hind wings. 



Venation. — Vein i of primaries is very rarely furcate at base, 4 and 5 are always 

 separate at base. On secondaries 4 and 5 are joined at base.
