Cocoons of the same kind are sometimes fonncl suspended 

 to tlie twigs of the ^YIUl cherry-tree, the Azalea, or swamp- 

 jiink, and the Cephalanthus, or Lutton-Lush, but not so 

 often as on the sassafras-tree. Two of them, hanging close 

 together on one twig, were once brought to nie, and a male 

 and a female moth were produced from these twin cocoons 

 in July, the usual time for these insects to leave their winter 

 quarters. Drury called this kind of moth Promeiliea^ a 

 mistake probably for Prometheus* the name of one of the 

 Titans, all of whom were fabled to be of gio-antic size. The 

 color of Attacus Proinethea differs according to the sex. 

 The male (Fig. 18G) is of a deep smoky brown color on the

 m both, the wings are crossed by a wavy whitish line near 

 the middle, and have a wide clay-colored border, which is 

 marked by a wavy reddish line ; near the tips of the fore 

 Avings there is an eye-like black spot within a bluish-white 

 crescent ; near the middle of each of the wings of the female 

 there is an angular reddish-white spot, edged with black ; 

 these angular spots are visible on the under side of the wings 



* Atlas was the brother of Prometheus, and this name, it will be recollected, 

 has been given to another of the Bombyces, an immensely lai-ge moth from China.
