Family TORTRICIDAE. 
Phaecasiophora,'* n. g. 
Differs from any known Tortricidian genus by the structure of 
the male hind tibiae. In Penthina the tibiae have a tuft of hairs 
lying in a depression on the surface of the joint. In Phaecasiophorz 
the joint is covered with long and coarse scales standing out from 
it and, in mutabilana, from their white color, giving the tibiae 
the appearance of being wrapped in wool or cotton (Plate 2, 
fig. 6). The form is robust, the abdomen notably long. The 
palpi are porrect, coarsely scaled, with small third joint. The pri- 
maries are rather broad with parallel margins, 12-veined, all the 
veins separate (Plate 2, fig. 5a). Hind wings 8-veined, cell closed 
by an aborted veinlet, 3 and 4 from one point, 5 immediately ap- 
proximate (Plate 2, fig. 5d).

Primaries crossed by three darker, broad, bent, sinuously edged bands not 
attaining internal margin, with paler interspaces medially traversed by darker 
shade lines. On the middle band at its outer edge, about the extremity of the 
cell, is an ill defined whitish spot. Between the middle and outer dark bands 
9 Gr.: gakdovov et dépa. Kraftig gebaut mit verhaltnissmissig langem starkem Hinter- 
leib. Von allen mir bekannten Gattungen dieser Zunft durch die im mannlichen Geschlechte 
grob, lang and herauf beschuppten Hinterschienen verschieden (Tafel 2, fig. 6). Durch die 
weisse Farbe erscheinen die Hinterschienen bei mutabilana é wie mit Wolle unhillt. Vorder- 
fliigel breit mit kaum hervortretender Spitze und Penthinen—artigen Zeichnung, auf dem 
Mittelfelde ein weislicher Punkt; 12 Rippen, alle gesondert, 3 und 4 nicht aus einen Punkte 
entspringend, Theilungs Rippe unvollkommen (Tafel 2, fig. 5a). Hinterfliigel mit gleich massig 
langen Fransen; 8 Rippen, 3 und 4 aus einem Punkte, 5 gleich dahinter; Theilungs Rippe faden- 
formig, aber fortgesetzt (Tafel 2, fig. 50),
