494 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



28. Drepana sp. 



A pupa taken July 5, 1883, at Cambridge, Mass., upon Betula alba^ 

 upon which the larva had evidently fed, gave as imago, July 16, 1883, 

 a species of Drepana.~{Mr8. Dimmock, Psyche, iv, p. 279.) 



29. Gastropacha 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 americana Harris (Rep. Ins. lujur. Veg., 1841, p. 273-274). This author 

 (I. c. 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 

 Fraxinus. Lintner (Entom. Coutrib., No. 1, 1869, p. 193), in a note upon the larva> 

 gives Betula as food-plant and later (Entom. Coutrib., 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 f o llowing eight species of Noctuidte or 

 owlet moths are extracted from Mrs. Dimmock's Insects of the Birch, 

 in Psyche, iv, pp. 273-274 : 



30. Orthosia instahilia Fabr. 



Orthosia inatabilia Fabr. (Entom. Syst., 1793, v. 3, p. 119) [= Tceniocampa ivcerta 

 Hiibu.]. Kaltenbach (Pflauzenfeinde, 1872, pp. 429-430, 550, 640) gives thefollow- 

 ng food-plants for the larva of this species in Europe : Apple, Ulmua, Tilia, Salix, 

 Quercus, Fraxinus, Betula alba, Populus, and Carpinus; to this list Roiiast (Annales 

 Soc. Linu. Lyon, Ann. 1882, [1883], N. S., v. 29, pp. 315-316) adds Amygdalus com- 

 munis, Cratwgus oxyacantha, and Centaurea jacea. 



31. Apatela xyliniformis Guen. 



Apatela xylinif or mis Gnen. (Hist. Nat. d. Ins., 1852, v. 5, Noct., v. 1, p. r>6). Thax- 

 ter (Papilio, Jan. 1883, v. 3, p. 17) states that the larva of this species feeds on Betula 

 and blackberry (Ruius). 



32. Apatela hrumosa Guen. 



Apatela hrumosa 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 dactijlina Grote (Proc Bost. Soc. Nat. 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 

 eats 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, 1862, p. 436-437) figures 

 larva, pupa, 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,
