140 THE CANADIAN ENTOMOLGIST. 



Bucculatrix crescentella, n. sp. 



Face whitish, tuft on the vertex whitish, more or less inter- 

 mixed with ochreous or dark brown hairs. 



Fore wings usually brown; sometimes paler, almost bufifish 

 ochreous. A whitish streak, sharply defined in dark specimens, 

 extends from the base for one-half the wing length abo^•e the fold: 

 immediafeh- lieneath the ground colour is somewhat darkened. 

 At the middle of the costa is a narrow oblique curved white streak, 

 concave outwardly; beyond it a less oblique white streak pointing 

 toward the tornus; between these streaks the ground colour is a 

 darker brown. On the middle of the dorsum is a half crescent- 

 shaped dark brown spot, bordered before and behind with whitish. 

 A triangular white spot immediately precedes the apex and lies 

 above an irregular black spot, beyond which a line of dark scales 

 crosses the apical cilia. Hind wings gray, brown or ochreous 

 tinged. 



Legs \ellowish, marked with fuscous; hairs on posterior tibiic 

 pale ochreous. 



Expanse: 7-9 mm. 



Described from a series of bred and captured specimens. This 

 is one of the commonest species around Cincinnati; it occurs also 

 at Toronto, Canada. Mines may be found plentifully on species of 

 Compositcc belonging to several genera {Aster spp., Solidago spp., 

 Erigeron spp.). The larva makes a trumpet-shaped mine, gradually 

 increasing in diameter and marked by a central line of frass. On 

 rare occasions it deserts one mine to form another, but is at no 

 time an external feeder. The cocoon of the usual Bucculatrix type 

 is a white elongate ribbed structure. ' 



Lyonetia Candida, n. sp. 



Face, palpi and antennal eye-cap silvery white; antennal stalk 

 gray Tuft on the vertex white, with a few blackish hairs, especialK' 

 behind. 



Fore wings shining pure white, except in the apical part. 

 Just before the costal cilia is an oblique triangular grayish streak, 

 apparently formed by the confluence of two narrower streaks, 

 which are sometimes indistinctly separated from one another by 

 •white ground colour. This is followed by three perpendicular, 

 slightly curved black streaks in the cilia preceding the round black
