.cybele is to be seen, and both sexes abound in the clover fields. By the 

 end of June cybele has become scarce, and the individuals to be seen have 

 lost their freshness and are broken and worn. It is certain that these 

 early appearing females have not matured eggs and laid them, because at 

 no time from June to August will anything but rudimentary eggs be found 

 by dissecting, and the eggs do not become distinguishable to the eye 

 until August. They then mature rapidly, and in a few days attain full 

 •size. I am confident that no eggs are laid till August. But about the 

 first of that month and all along to near the end of it, there appear in 

 great numbers both fresh males and females, as if just from chrysalis, with 

 no abrasion of the hairs on thorax between the wings, which spot is the 

 first to show wear. (I doubt if an Argynnis could fly two days without 

 thus giving evidence of it.) There are flying at the same time many worn 

 individuals, especially females. These last are the first to deposit their 

 eggs, but shortly after, and up to the time of frosts, the others also are in 

 condition to do the same. I see no explanation of the appearance of 

 these freshly emerged butterflies than that they have formed part of the 

 brood of caterpillars hatched the previous fall, some of which brood 

 yielded the butterflies that came out in May and June, and the remainder 

 continued in the larval or chrysalis state until August, and upon these last 

 the perpetuation of the species largely depends, for nine-tenths of the June 

 flight must have been destroyed long before August. If [ am right, the 

 preparatory stages of the August cybele must consume eleven months out 

 of the twelve.

Expands i i inches. Primaries light gray, the outer third brownish, 

 with a triangular gray spot near the apex. A narrow black line near the 

 base of the wing extends from the costa to the submedian vein. Parallel 

 to this and farther out, a black patch, narrowest at the costa and broadest 

 on the second median veinlet, extends nearly across the wing, ending 

 at the submedian vein. A triangular black patch surrounds the brownish 

 reniform spot, and immediately back of this a curved black line reaches 

 from the sub-dorsal vein to the second median veinlet. The secondaries
