 slightly shining ; edge of tongue-sheath shining and mesially 

 channelled ; head, thorax and sides of tongue-sheath coarsely, 

 superficially wrinkled ; wing-case with the veins broadly 

 prominent, the surface more minutely wrinkled ; segment 3 

 with some pits behind the spiracle of 2 ; abdomen very finely 

 transversely wrinkled and shallowly pitted ; hind bevels 

 of 8 to 10 smooth, front bevels of 9 to 11 minutely pitted. 

 Spiracle of 2 a narrow slit lying between the slightly raised,

Habits. — Food-plants : Jussisea repens Linn., family Ona-

 feeding at flowers after dark, but have not known of them 

 coming to light.
