Actias (Attaciis) Luna Linn. — The body is white, 

 with clear green wings ; each wing marked with an eye 

 spot ; a reddish brown band extends across the thorax 

 and the whole length of the upper edge of the fore 

 wings ; posterior wings prolonged into long tails. This 

 moth expands nearly five inches. The larva; feed 

 upon walnut, hickory, sweet gum, beech, birch, willow 

 and plum. The cocoon is similar in form to that of 

 Polyphemus, but it is not so dense, and is sometimes 

 of a brown color. (3, IV., 123). 



Samia {Attacus) Cynthia Drury is an introduced 

 species of which a few specimens have been taken in 

 this place. Many specimens have been bred here, by 

 members of the University, from eggs obtained in 

 Brooklyn, L. I. This is probably the explanation of 

 its occurence in this locality. The larva: feed upon 

 the Ailanthus. The cocoon is similar to that of 

 Prometkia. The goods known by the name o( At/an- 

 tinc are made from the cocoons of this species. (3, 

 IV., 112). 



Callosamia (Attacus) Promethia Drury. This species 

 is closely allied to the above. The sexes differ greatly.

 upper side, and the female light reddish brown ; in 

 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 wings there is an eye-like black spot within 

 a bluish white crescent." (2. 390). Expands three and
