rather wide in the middle, and diminishing to a point at either 

 end. 



Below, the under wings have a row of six narrow blue 

 crescents, and above each of these is a semilunar mark of brick- 

 red. This insect is a native of Mexico. 



In the insect which is depicted on page 556 we have an 

 example of the effects which can be produced by the arrangement 

 of only two colours. There are few handsomer Butterflies than 

 Papilio Palinurus, in which black and green are the only colours 

 on the upper surface.
