In July we found eggs and larvae on somewhat larger 

 bushes, say two to four feet high, and on leaves below the 

 tender end ones. Later in the year when fresh leaves are 

 scarce all the foliage of the bushes was searched with success, 

 but the trees (ten to twelve feet high) rarely yielded any- 

 thing. 



The eggs are little larger than mustard seeds, spherical, 

 pale green or sometimes streaked or blotched with red, a fea- 

 ture often noticed on the eggs of such sphinges as Smerinthus 

 geminahts, S. myops, S. exccecatns, and .5". modeslus. The 

 black eggs we saw were, doubtless, parasitized. 



In the searches for eggs and larvae of ajax, eggs and larvae 

 of the "hawk," Dolba hylceus were often found, these latter 

 eggs differing from the former in size, mainly being deposited 

 on the underside of the leaf (rarely on the upper side). 



Of course there is no mistaking the larva of Dolba, as it is 

 pale green, slender, with caudal horn and sphingial bands. 

 In all stages of the larva of ajax the thoracic region is swol- 

 len. The odor from the retractile thoracic tubes of the larva 

 of ajax is stronger than and entirely different from that of 

 other Papilio larvae with which the writer is acquainted. 



Of the chrysalids we obtained, about one- twelfth only were 

 green, the rest being light reddish or yellowish-brown. 



Like other Papilios, ajax is often seen in great bunches at 

 damp, sandy or muddy places, but more rarely at flowers. The 

 seasonal variation in this insect is well-known to collectors as 

 also the differences in the depth of the coloration. 



Stemmed Cocoons of Telea polyphemus. 



BY DR. R. E. KUNZE, Phoenix, Arizona. 

 During the season of 1889 and including 1892, I collected 

 immense numbers of Saturnian cocoons, within a radius of two 

 to ten miles from New York City, which were exchanged at 

 home or sent abroad. The localities included the banks of the 

 Harlem River, Palisades, the Hudson, swamps of the Hacken- 

 sack and the Passaic Rivers, low lands of the tongue of land 

 between New York and Newark Bay, Staten Island, Flatbu^h, 

 Brooklyn and Long Island City.
