494 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
I) rt puna sp. 
A papa taken July 5, 1883, at Cambridge, Mass., upon Betula alba y 
upon which the larva had evidently fed, gave as imago, July 16, 1883, 
a species of Drepana. — (Mrs. Dimmock, Psyche, iv, p. 279.) 
29. (iatstrupacha americana Harris. 
Though I have found the larva of this moth on the walnut, it appears 
by the following summary of its habits to live at times on the birch. 
Gastropacha amtricana Harris (Rep. Ins. Injur. Veg., 1841, p. 273-274). Thisauthor 
(I, o. and Treatise on Ins. Injur. Veg., 1862, pp. 377-378) briefly describes the larva, 
which he states feeds upon apple, and on authority of Abbot, upon Quercus and 
Fraxinua. Lintner (Entom. Contrib., No. 1, 1869, p. 193), in a note upon the larva, 
gives Betula as food-plant and later (Entom. Contrib., No. 3, 1874, p. 154,155) 
describes the larva, which he states to feed on Betula lenta and Acer. Lyman (Can. 
Entom., Aug., 1874, v. 6, p. 158) describes the eggs of this species. (Mrs. Anna K. 
Dimmock, Psyche, iv, p. 274.) 
The biological notes on the following eight species of Noctuidse or 
owlet moths are extracted from Mrs. Dimmock's Insects of the Birch, 
in Psyche, iv, pp. 273-274 : 
30. Ortho8ia instabilis Fabr. 
Orthopia instabilis Fabr. (Entom. Syst., 1793, v. 3, p. 119) [= Tamiocampa incerta 
Hiibu.]. Kaltenbach (Pflauzenfeinde, 1872, pp. 429-430, 550, 640) gives the folio w- 
ng food-plants for the larva of this species in Europe: Apple, Ulmus, Tilia, Salix, 
Quercus, Fraxinus, Betula alba, Populus, and Carpinus; to this list Roiiast (Annales 
Soc. Linn. Lyon, Ann. 1882, [1883], N. S., v. 29, pp. 315-316) adds Amygdalus com- 
munis, Crataegus oxyacantha, and Centaurea jacea. 
31. Apatela xyliniformis Guen. 
Apatela xyliniformis Guen. (Hist. Nat. d. Ins., 1852, v. 5, Noct., v. 1, p. 56). Thax- 
ter (Papilio, Jan. 1883, v. 3, p. 17) states that the larva of this species feeds on Betula 
and blackberry (Rubus). 
32. Apatela brumosa Guen. 
Apatela brumosa Guen. (Hist. Nat. d. Ins., 1852, v. 5, Noct, v. 1, p. 52). Thaxter 
(Papilio, Jan. 1883, v. 3, p. 17) states that the larva of this species feeds on Betula. 
Salix, and Populus. 
33. Apatela dactylina Grote. 
Apatela dactylina Grote (Proc Bost. Soc. Xat. Hist., April 1874, v. 16, p. 239), 
Thaxter (Psyche, May-June [9 July], 1877, v. 2, p. 35) gives Betula and Salix as 
food-plants of the larva of this species. 
34. Apatela americana Harris. 
Apatela americana Harr. (Rep. Ins. Injur. Veg., 1841, p. 317). Harris (op. cit., p. 
317-318) describes the larva and cocoon of this species ; he writes: " The caterpillar 
eatfl the leaves of the various kinds of maple and sometimes also those of the elm and 
chestnut.* The same author (Treatise on Ins. Injur. Veg, L862, p. 436-437) figures 
larva, papa, and imago of this species, and adds Tilia to the food-plants; and 
(Entom. Corresp, 1869, p. 311) again describes the larva. In Amer. Entom., April,
