Figures 178, 179, and 180 represent the work of three leaf-rollers not 

 yet identified. 



75. Argyresihia gwdariella (Linn.). 



The histories of this and the next Tiueid have been sketched as fol- 

 lows by Mrs. Dimmock : 



Argyresthia gocdarteUa Liun, (Syst. Nat., 1758, ed. 10, p. 897.) Fabricius (Syst. 

 Eutom., 1775, p. 664) writes of this species " Habitat in Aluetis, in betulse geminis,"^ 

 and Kaltenbach (Pflauzenfinde, 1872, pp. 604-605) states that the larvse of this species 

 live in the catkins of Betula and Almis. Chambers (Can. Eutom., August 1875, v. 7, 

 pp. 144-145) notes the discovery of this species in North America, and, after describing^ 

 the imago, adds: "The larva feeds under the bark and in th8' 

 young shoots of the birch in March and April." A. Balding 

 (Entom. MonWily Mag., February 1885, v. 21, pp. 203-206) de- 

 scribes the larva, which he found feeding in catkins of Betula and 

 Alnus. (Psyche, iv, 241.)

76. Cryptolechia eonfertella Walker. 



Cryptolechia eonfertella Walk. (List Lep. Ins. Brit. Mus., 1864, pt. 29, p. 563). The 

 larva? of this species are common upon Betula alba during August and the early part 

 of September. The larva feeds in a rolled portion of the margin of the leaf, where 

 pupation takes place, lasting from three weeks to a mouth. (Psyche, iv, p. 241.) 



77. Bucculatrix canadensisella Chambers. 



Regarding this Tineid, Prof. J. A. Lintner writes me as follows: 

 As you have published on Bucculatrix, it will interest you to hear that I am breed- 

 ing B. canadensisella Chambers (Can. Ent., vii, p. 146) from the yellow birch (Betula 

 lutea). 



Professor Lintner has kindly sent me the following account of this 

 insect in advance of his report contained in the Report of the Regents of
