July, '07] ENTOMOLOGICAL NEWS. 307 



ber of The News, the larvae that gave me over a hundred 

 chrysalids were gathered from June ist to October ist, few 

 of the number emerging from July to October. Why so few 

 of the chrysalids gave butterflies during the summer and 

 autumn is a little strange, but doubtless a wise provision of 

 nature to prevent the extinction of the species. 



Another interesting observation on these ajax pupae is that 

 every one of the seventy-nine spring imagoes are of the winter 

 varieties, despite the fact that many of them should have given 

 summer forms last year, and all of them escaped a freezing 

 temperature last winter. 



In a majority of the specimens of the winter forms of imago, 

 the ground color is from a pale cream on the hind wing to a 

 light blue-green on the front wing, with cross bands of dark 

 brown or black and a double red spot at the anal angle, separa- 

 ted from the two blue lunules by a cream-colored spot. In a few 

 specimens the double red spot gives place to two separate 

 spots. In a number of the imagoes the usual pale blue-green 

 ground color of the front wing is replaced by a very light 

 or pale smoky yellow. 



A few specimens have the outer border of the forewing full 

 or convex. 



In specimens of the so-called variety abbottii, a more or less 

 distinct crimson streak occurs on the upper side of the hind 

 wing near the middle and just outside of the medial black 

 band. 



In one specimen this red is a distinct spot with an outer 

 black shade line. On the first day of May, 1906, I collected 

 twenty-three eggs and three young larvae of ajax. So back- 

 ward had been the spring that few of the leaves had at all 

 opened out, and so the eggs were found on the lower side, 

 exactly the opposite of the finds last summer and autumn. 

 As before, they were found largely on the low, young shrubs. 

 On May 18th, I had the first two pupae of the summer brood, 

 one green and one brown. Seventeen days from the emergence 

 of the last winter imago I had the first pupae. 



After collecting the above eggs, a series of killing frosts 

 left all exposed papaw bushes without leaves or blooms, and 

 doubtless killed the young larvae as well.
