164 LEPIDOPTEEA OF NORTH AMERICA. 



The legs are long and the two exterior spurs of the hind tibise 

 very short, the two interior long. Male. Antennae ciliferous. 

 Female. Antennae simple. 



Larva. Head small and elongate-globose, caudal horn rather 

 short, nearly straight and rough. ' Without oblique bands, but 

 with a row of subdorsal spots on each side. The anterior seg- 

 ments are much attenuated, and are capable of being withdrawn 

 or shortened or much extended; none of the segments dilated. 

 When disturbed, they fall from their food-plants, shorten the ante- 

 rior segments and bend the head toward the terminal extremity. 

 In repose, the anterior rings are merely shortened. The larval 

 transformation takes place in a superficial cell excavated from the 

 surface.
