 " The caterpillar, which eats little, and grows slowly, spends most of its time at 

 rest motionless, on the upperside of a leaf of precisely the same tint as itself. A 

 dorsal line, or row of spots, however it may look on paper, succeeds in keeping up 

 the continuity of the midrib of the leaf in a way whicli cheats the sharpest eye, 

 while the long interlaced spines, extending on each side, fall in with the neuration "

 cilia dark brown. Forewing with a transverse inner-discal broad obscure blackish 

 sinuous-edged fascia, and a narrow submargiual lunular fascia. In some specimens 

 are faint traces of small incipient whitish lunate marks on the outer upper edge of

 transverse discal white narrow macular band, commencing from middle of the costa 

 and extending to lower median veinlet near its end, the spots somewhat cordate, the 

 lower posteriorly elongated or sometimes nearly or quite broken across its middle ; 

 beyond are two obscurely-defined very small white subapical spots. Underside as 

 in the male, except that the transverse discal oblique white macular band, and the 

 slightly-defined subapical small white spots, are present.
