Figures 178, 179, and 180 represent the work of three leaf-rollers not 
yet identified. 
75. Argyresihia goedarlella (Linn.). 
The histories of this and the next Tineid have been sketched as fol- 
lows by Mrs. Dimmock : 
Argyresthla gcedartella Linn. (Syst. Nat., 1758, ed. 10, p. 897.) Fabricius (Syst. 
Entom., 1775, p. 664) writes of this species " Habitat in Alnetis, in betulse geminis,' ? 
and Kaltenbach (Pflanzenfinde, 1872, pp. 604-605) states that the larvae of this species 
live in the catkins of Betula and Alnus. Chambers (Can. Entom., 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 tho 
young shoots of the birch in March and April." A. Balding 
(Entom. Monthly 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. CryptolecJiia confertella Walker. 
CryptolecJiia confertella Walk. (List Lep. Ins. Brit. Mus., 1864, pt. 29, p. 563). The 
larvae 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 month. (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
