(Plate IV., fig. 19 <?, 20 ? .)

The expansion of the wings is from 1J to If inches. The fore-wings are light ochreous with 

 the veins white ; there is a shaded, brownish, longitudinal streak near the apex, another from the 

 end of the cell to the termen, a stronger streak from the base of the wing to near the tornus, and 

 another along the dorsum ; there is a minute black dot near the base above the middle, a slightly 

 larger dot at about one-third, a conspicuous dot between the origins of veins 3 and 4, and a very 

 minute dot on vein (5. Hind-wings dark blackish-grey, cilia paler. 



The perfect insect appears in February, and has been taken at sugar. 



Described and figured from specimens in Mr. Fereday's collection.
