Mr. E. Meyrick on the classification 



double row of short spine-like dark scales on lower 

 margin of cell in disc beneath. The development of the 

 family has proceeded on two lines, the ancestral form 

 being near to Agdistis ; one line being by way of 

 Plati/j^tilia and Oxyptilus to Trichoptilus, the other 

 through Stenoptilia, Aliicita, and Crasimetis to Ptero- 

 phoriis. The extreme genera of both lines have the 

 neuration much degraded.

Face without tuft, rouuded ; ocelli obsolete ; tongue developed. 

 Antenna3 two-thirds, in ^ ciliated (| — |). Labial palpi moderate, 

 ascending, second joint with short projecting scales beneath, 

 tending to form a short angular apical tuft, terminal joint short or 

 long, filiform, tolerably pointed. Maxillary palpi obsolete. Tibiae 

 thickened with scales on origin of spurs, outer spurs nearly equal 

 inner. Fore wings bifid, cleft from before middle ; vein 2 out of 4 

 or absent, 3 absent, 5 and G extremely short, 7 absent, 9 absent, 

 10 from near 8 or absent, 11 from near 8, long. Hind wings trifid, 

 third segment with more or less developed tooth of black scales in 

 dorsal cilia, often slight ; vein 2 from middle of cell, 3 absent, 

 5 and 6 very short, 7 to apex.
