with large tubercles colored green, blue, yellow, and red. 
Mrs. Dimmock has contributed to Psyche (iv, p. 276) the following his- 
torical sketch of this insect. 
Attacus cecropia Linn (Syst. 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 (Entom. 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. Entom., 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. Sprague (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-
