siderable extent pink. There is usually a dark discal spot 

 on the fore wings, upon which, especially in the males, there 

 may be two white dots. This species is more common in 

 the Southern States than in the North. The expanse of 

 wings in the male is two inches ; in the female, two and one 

 half inches. The larva feeds on the leaves of the Honey- 

 locust and of the Kentucky Coffee-tree. 



Anisota (An-i-so'ta). — To the genus Anisota belong three 

 species of moths that occur in the Eastern United States. 

 These moths are dark yellow, purplish red, or brownish in 

 color, and agree in having the fore wings marked with a 

 white discal dot. The larvae feed on the leaves of oak; they 

 are more or less striped and are armed with spines. These 

 insects hibernate as pupae. 



In determining these moths the student should remem- 

 ber that the two sexes of the same species may differ more 

 in appearance than do individuals of different species but of 

 the same sex. The sexes can be distinguished, as already 

 indicated, by the antennae. The three species can be sepa- 

 rated as follows :—
