PLATE I. 



Habrocestum spleudens : Male and female, to show the 

 difference between the sexes ; first three moults, to show the 

 greater resemblance of the young to the female ; variety of the 

 female. 



Habrocestum peregrinum and Habrocestum auratum 

 males, to show the departure in that sex from the general 

 coloring of the genus; note that the female of splendens resem- 

 bles these males more than she does the male of her own 

 species.
