 diameter than the front margin of 12 and deeply undercut, 

 especially in the dorsal area. Surface smooth, moderately 

 shining in dorsal area and dull in ventral ; a deep transverse 

 gash on dorsum at the common margin of segments 4 and 5, 

 and a less conspicuous gash at the common margin of 5 and 6. 

 Spiracle of 2 a curved slit, the remaining spiracles oval, 

 flush, the slit with narrow raised edges. Cremaster a thin 

 shaft, tapering gently to the truncate tip, the surface irre- 

 gularly wrinkled to near the tip. Colour pale ochreous with 

 a pinkish shade, dorsum of abdomen strongly suffused with

Habits. — Food-plants: Vitis Linn., family Ampelidea?, and

 been observed.
