Mrs. Dimraock has contributed to Psyche (iv, p. 276) the following his- 

 torical sketch of this insect. 



Attacus cecropia hinn (Ryst. Nat., 1758, ed. 10, p. 809). Harris (Rept. Ins. Injur. 

 Veg., 1841, p. 279-280) describes the larva, imago and cocoon of this species; later 

 (Treatise on Ins. Injur. Veg., 1862, p. 385, 387-389) he adds figures of the larva, pupa, 

 cocoon, and male imago; and still later (Eutom. Corresp., 1869, p. 294-295) he again 

 describes the larva. Morris (Synop. Lepid. N. A., 1862, p. 223-224) describes larva, 

 cocoon, and imago. Trouvelot (Amer. Nat., March 1867, v. 1, p. 31) gives a note on 

 the cocoon. Riley (Amer. Eutom., Feb. 1870, v. 2, p. 97-102, and 4th Ann. Rept. State 

 Entom. Mo., 187 ', p. 103-107) describes the eggs, and figures and describes the larva, 

 pupa, cocoon, and male imago. Spragne (Can. Entom., April 1870, v. 2, p. 82) de- 

 scribes the eggs. Saunders (Can. Entom., Oct. 1871, v. 3, p. 149-155) figures and de- 

 scribes the larva, cocoon, and male imago. Lintner (Entom. Contrib., No. 3, 1874, p. 

 125) describes the young larva. Worthington (Can. Entom., Sept. 1876, v. .8, p. 165- 

 166) notices some color varieties of the imago. Gentry (Can. Entom., March 1877, v. 

 9, p. 41-49) describes the egg, different stages of the larva, and cocoon. Grote (Can-
