m:idc on the larva or the cocoon, but the cast skins found in tlie mine 

 arc identical with those of Marmara salictd/a Clemens, and thci-e is no 

 doubt whatever but that the larva while in the mine is flat, stront^ly 

 sconiented and looloss, and that it, after castino- its last skin in the 

 mine, assumes a cj^lindrical form with well-developed le<^s and pro- 

 leos, and spins its cocoon in some convenient corner, presumal)]y with 

 the same strange u-lobules for ornamentation as Jf. mllctrlhi. 



The species is very close to 21. miicteUa but larger, and distinguished 

 by the dark head. 



From the same leaves which contained the mines of this insect was 

 bred Cojjtodisca arhatlella Busck (see p. 769). 



Bred specimens were received also from Professor Kincaid.

 A large well-preserved series bred at Kaslo, British Columbia, by 

 Doctor Dyar from Ceaiwtlvus, Prtmus, and Betula,' also captured 

 specimens from same locality (Cockle). 



As already realized from the examination of the types and descrip- 

 tions all the above names are synon3anous. With the present excellent 

 and abundant bred material (nearly 150 specimens) this contention is 

 amply verified. The series comprises every variation from specimens 

 with the pure silvery white ground color to specimens with this color 

 thickly overlaid with dark scales. Similar variation is found in the 

 European species of the genus. 



LYONETIA SALICIELLA, new species. 



Antennae greenish fuscous. Labial palpi and face white, with a 

 greenish tinge. Tuft on head dark, consisting of black, white, and 

 fuscous scales. Eye caps and thorax light golden green. Forewings 

 golden green with a few irregularly scattered black dots, and with a 

 silvery-white longitudinal streak in the middle of the wing from l)ase 

 to apex. Apical part of the wing and cilia white, with a round l)lack 

 apical spot and black apical pencil, and with three costal and two 

 dorsal l)lack perpendicular dashes in the cilia, rndersidc of body 

 silvery white. Legs silvery white, except the iiind tibia", wliich are
