 pearance. 



The Ceratocampidce are called the Royal Moths and 



include the Regal moth, 



probably the largest of 

 the whole group, the larvae 

 of which is called the Wal- 

 nut-worm or the " hickory 

 horned-devil," and the 

 Imperial-moth. The Regal 

 is of a rich, reddish brown 

 color, splotched with yel-

 yellow with variable pur- 

 plish-brown shadings. 

 Both have rather nar- 

 rower fore-wings than 

 the Saturniids. Smaller 

 species of this family are 

 the Rosy Dryocampa and 

 the Senator. 



With the exception 

 of the Rosy Dryocampa 

 and the Cecropia, which 

 are sometimes injurious 

 to shade trees, none of 

 these species can be con-

 portance, but the family 

 will, nevertheless, remain
