THE BUTTERFLY HUNTERS. 39 



the row of yellow spots on the margin are seven blue 

 spots. By the side of the blue spot at the hind angle 

 is an orange spot, with a black dot in the centre. All 

 the spots on the under side are dull orange. The female 

 Papilio Asterias has but one row of yellow dots on the 

 front wings. 



"This kind of butterfly is most numerous during the 

 month of July. You will often find it in your gardens, 

 hovering over beds of Parsley and sweet-scented Phlox. 

 It deposits its eggs on these plants, and it is there that 

 the caterpillar we have already spoken about feeds. It 

 often does much mischief by eating the leaves of Parsley 

 and Carrots. 



"As the Troilus butterfly resembles the Asterias so 

 closely while in the winged state, I will describe it to 

 you now. It appears about the middle of June. This 

 kind is never very numerous, but perhaps some of you 

 will be so fortunate as to find a specimen. The Papilio 

 Troilus has but one row of yellow dots, and that is on 

 the margin of both the fore and hind wings. The green 

 on the hind wings is shaded into the tint of the wing, 

 instead of being in distinct spots like the blue in the 

 Asterias, and the orange spot has no black dot in the 

 centre. The difference between these two butterflies is 

 so slight that it is impossible to distinguish one from the 

 other when they are on the wing."
