 caterpillar that hides beneath 

 the milk-weed leaves, and her 

 emerald -green chrysalis stud- 

 ded with golden buttons. And 

 what can she teach us? Her 

 lesson is an interesting one, 

 for I suspect that the Ar- 

 cliippus can see further into 

 the milk-weed tribe of 

 plants than most of the 

 botanists. The common 

 silk-weed is her favorite, 

 but if you search you 

 may find her caterpillar 

 broods on various of our 

 other milk-weeds, of 

 which there are a dozen 

 or more. 



But how is this? xf r ""'' ? 

 Here I find them ^ ;* 

 upon the dog-bane ! 

 What does our botany 

 say to this? The dog- 

 bane is not included in 

 the milk-weeds, though it 

 is the next family in the flora, while 

 its opposite leaves, milky juice, pods 

 with silky seeds, and other resem- 

 blances in the flower, would certain-

 the family. And as we look back into
