256 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, XVIII., 



Posterior tibiae usually rough-haired. Forewings : lb furcate, 2 

 not widel}^ remote from 3, 7 and 8 stalked (occasionally coincident). 

 Hindwings sometimes over 1, more or less trapezoidal, termen 

 usually sinuate or emarginate, 6 and 7 frequently approximated 

 or stalked, 8 more or less distinctly connected with cell in middle. 



Assuming that the Xyloryctidoi are maintained as a distinct 

 family (which still appears to me to be convenient, though I think 

 ultimately it must be reduced to a group of the Gelechiadce), I 

 rely for distinction mainly on the character of vein 2 of the fore- 

 wings, which in that group rises widely remote from 3 (generally 

 disproportionately so); considering this in combination with other 

 characters, I have not hitherto found any species as to which I 

 had the least doubt. From other families the Gelechiadm are 

 most reliably distinguished by the connection of 8 of hindwings 

 with cell by a more or less evident bar; this is not always easy 

 to observe, but the sinuation or emargination of termen is usually 

 perceptible, and where this fails, the greater width of hindwings 

 relatively to forewings, or the approximation of veins 6 and 7 at 

 base are frequent characters which help to distinguish from the 

 Oeco2:>horid(B, in which family they never occur.
