Ninay Valley, Central Arfak Mountains, Dutch New 

 Guinea, 3500 feet, November 1908 to January 1909. Type 

 in coll. L. B. Prout. A second ? , Fak-Fak, 1700 feet, 

 January to February 1908, slightly more reddish above and 

 slightly more ochreous beneatii, but quite similar, also in

 trace in the cotype. 



Leptoctenopsis uxorcula, sp. n. 



5 . 28 mm. — Very closely related to W2e?u««a, Prout, Gen. 

 Ins. fasc. 104-, p. 82, of which it may possibly be a form, 

 though the fore wing appears to be slightly more squared at 

 tornus; ground-colour paler, the antemedian line somewhat 

 more curved, the postmedian paler, shaded proximally with 

 pale yellowish and on fore wing sharply dentate outwards in 

 the cellules on either side of SC.
