 cilia white, bases pale-fuscous.

Type in Coll. Turner. 



N.A., Port Darwin ; one specimen received from Mr. 

 G. F. Hill. 



Gen. Perimeceta, nov. 

 TieQifirjXETog, long. 



Frons flat, oblique. Tongue well-developed. Palpi 

 long, porrect ; second joint very long, stout, smooth-scaled ; 

 terminal joint exposed, rather long, obtuse. Antennae of 

 ^ (unknown). Posterior tibiae with outer spurs half inner. 

 Forewings very long ; 8, 9, 10 stalked. Hindmngs normal. 



Probably allied to Otiophora, Turn., in spite of the 

 stalking of vein 10. The ^ may show additional 

 characters.
