 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 theWal- 

 nut-worm or the " hickory 

 horned-devil," and the 

 Imperial-moth. The Regal 

 is of a rich, reddish brown 

 color, splotched with yel- 

 low, while the imperial is 

 yellow with variable pur- 

 plish-brown sha dings. 

 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- 

 sidered of economic im- 

 portance, but the family 

 j will, nevertheless, remain
