8. A. zephyrana, Tr. ; dubrisaua, Cud. — Expanse

 thickly dusted with brown and silvery white dots. 



Antenna9 yellow-brown ; palpi, head and thorax dull 

 ochreous ; abdomen dull black, dusted with white. Fore 

 wings narrow, costa nearly straight, apex rounded, yet the 

 hind margin very oblique ; pale ochreous-yellow, marbled 

 with silvery -white dotting, which is placed mainly in trans-

Larva broadest at the second and third segment, tapering 

 to the anal extremity, segments deeply divided and ridged ; 

 yellow, the raised dots barely visible, and hairs minute ; 

 head rather broad, pale brown, with a brown line in front of 

 each lobe, enclosing the mouth, which is dark brown ; plates 

 shining pale yellow. 



September to April, and in a second generation in June 

 and July, in the stems of wild carrot {Daucus carota), eating 

 the pith and filling the vacant space with frass, continuing 

 in the dead stems through the winter and working back 

 through the frass, to spin up there in a slightly brown cocoon 

 in April. Abroad said to feed in stems of Eryiujium campesire, 

 Gnaphaliuni arenariuni, and Rhododendron hirsutum. 



Pupa pale yellow-brown, wing and limb covers thick,
