crossing the wings, between which, is a brown dash at the 

 end of the cell of each wing; border-lines three, the 

 inner crenate. Near the outer end of the fore wings, 

 below the costa, is a black eye-spot annulate with yellow 

 and pupilled with pale blue ; there is also a small one be- 

 tween this and the costa, and there are traces of three more 

 towards the hind margin. The hind wings have two 

 distinct ocelli, with a small one before the first, another 

 after the second, and traces of two more, with silver, 

 between the two. 



The egg is semiovoid, the base flattened, and the 

 sides at base rounded ; the surface under a low power 

 appears smooth, but under a high magnifying power it 

 is seen to be covered with shallow thimble-like depres- 

 sions. Color greenish white. 



In four days a larva .09 of an inch long hatches 

 from this. The shape is cylindrical, marked by five 

 or six longitudinal tuberculated ridges, each tubercle 

 emitting a clubbed white hair. Color white. Head 

 much larger than the second joint, bilobed, the vertices 

 without processes, black. 



After six days it moults the first time and is .2 of 

 an inch long, cylindrical, tapering both ways from the 

 middle, the last joint forked. The color is light green, 

 the tubercles white, with three green stripes ; legs and 

 under side green. After seven days it moults the second 

 time, the color being blue-green, the head yellow-green. 

 In six days it moults the third time, being then .42 of 

 an inch long, stout ; color pale green, with the tubercles 

 white, head emerald-green. It moults four times in 

 coming to maturity. 



The mature larva is .76 of an inch long, cylindrical,
