Larva— in mine on under-side of leaves of Fruniis communis 

 (spinosa, L.), P. domestica, and their cultivated varieties, vi — vii, 

 ix— iii. 



Pupa — iii — iv, vi — vii. Cocoon indistinct. 



Lmago — iv — v, vii — viii. 



Broods — two. Hibernates as full-fed larva inside the mine. 



Hah. — Enqland, generally distributed and common. Scotland, 

 Perthshire (teste Meyrick), Dumbartonshire (Bonhill, Malloch). 

 Ieeland, Dublin (teste Stainton). Central Eueope (including S. 

 France, teste Milliere). 



Imago — -Fore-wings shining, golden-ochreous, more or less irrorated with fuscous ; 

 basal white streak long and slender, slightly wavy, not unfrequently uniting with the 

 first dorsal tooth ; first dorsal and fii'st costal teeth long, narrow, oblique, sometimes 

 uniting so as to form an acutely angulated fascia. Costal and dcrsal teeth for the 

 most part black-margined internally. Dorsal margin between base and first tooth 

 with a narrow white line or a white spot. A black apical streak. Exp. at., 7 — 8. .5 

 mm. Posterior tarsi white, occasionally dark-spotted above. 



Rather smaller than cerasicolella, H.-S., ar.d of a totally difEerent 

 colour ; otherwise differing from the species that follow in the same 

 points as does cerasicolella. For the variety, in which the basal white 

 streak unites with the first dorsal tooth, it seems advisable to adopt
