from a blue black to black later. The eyes, antennae and 

 wings of the future adult can be plainly discerned. Head, 

 with a small tubercle at the proximal end of each antennae; 

 antennae shorter than thoracic legs. Thorax and appendages 

 roughened with indeterminate transverse striations; abdominal 

 segments also densely, coarsely punctate. Abdominal seg- 

 ments, five to seven with a flanged plate along the cephalic 

 margin. Length of male pupa 20 m. m. — 22 m. m. Width 

 7 m. m. — 8 m. m. The female pupa is about the same length 

 as the male, but from 2 m. m. — 3 .m. m. wider. 



The Adult. 



On emerging from the cocoon, the adult moth appears to 

 have only rudimentary wings with an abnormally large body; 

 they crawl for a short distance and start a rocking motion of 

 the body during which process, the wings gradually expand and 

 from half to three quarters of an hour after emergence, the 

 wings attain their full size. Copulation takes place shortly 

 after emerging if both sex are present, and lasts from one to 

 one and a half days. 



The Male Moth has a wing expansion of 45. m. m. — 48 m. 

 m. The upper surface of the fore wings are of a whitish color 

 but the under surface, also both surfaces of the hind wings, are 

 of a brownish yellow color. Both the upper and under surface 

 of the fore and hind wings bear prominent black spots, irregu- 

 larly placed and of various sizes. The dorsal surface of the 

 thorax is concolorous with the upper surface of the fore wings 

 and clothed with longish white hairs on the lateral margins. 

 The under surface of thorax is concolorous with under surface 

 of fore wings. The abdomen is concolorous with the hind 

 wings, with the exception of the last segment, which is white. 

 The abdomen has six rows of black markings, one dorsal, two 

 lateral and three ventral, which reduce in size as they approach 

 the end of abdomen. Length of abdomen 15 .m. m. — 17m. m. 

 Antennae black 7 m. m. — 8 m. m. long; legs with white, yel- 

 low and black markings. 



Thejemale moth has a wing expansion of 52. m. m. — 55. m. m. 

 Both upper and under sides of fore and hind wings are white; 

 the irregularly placed black markings are similar to the male. 

 The thorax and ventral surface of abdomen is white, but the 

 dorsal surface, with the exception of the first and last segments, 

 is a brownish yellow; six rows of black markings similar to
