Family TORTRICIDAE. 



Phaecasiopliora,'^ n. g. 



Differs from any known Tortricidian genus by tlie 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 Phaecasiophora 

 the joint is covered Tvith long and coarse scales standing out from 

 it and, in inutahilana, 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. ba). Hind wings 8-veined, cell closed 

 by an aborted veinlet, 3 and 4 from one point, 5 immediately ap- 

 proximate (Plate 2, fig. bh).
