Larva — m mine on under-side of leaves o£ CratcEgus oxyacantha ; 

 also, but sparingly, on Pyrus aucuparia {teste J. H. Wood). Two 

 specimens in Prey's collection are indicated as having been bred at 

 Ziirich from a foreign ("exot.") Cratcsgus. vi — vii, ix — x. 



Pupa — X — iv, vii. Cocoon indistinct. 



Imago — \v — v, viii. 



Proods— two. Hibernates as pupa. 



Sab. — England, generally distributed and common. Central 



EUBOPE. 



Imago. — Fore-ioings shiniiig orange-fuscous in the <?, brownish-orange in the 

 ? ; basal white streak of moderate length and breadth, black-margined above, rarely 

 uniting with first dorsal tooth ; first dorsal white tooth broad and conspicuous. 

 Costal and dorsal teeth internally biack-margined, often with some black scales 

 clustered round their apices. Dorsal margin between base and first tooth generally 

 with a narrow white line, or small white spot. A black apical streak. I^xp. al., 

 6.5 — 8 mm. Posterior tarsi generally more or less dark-spotted, sometimes plain. 



Smaller and much darker than blancardella, F., but rather similar 

 in colour to pyrivorella, sp. n., though separated from it by its much 

 smaller size, and from both it and mespileUa, Hb., by its generally 

 having a white line or spot on the dorsal margin near the base. It is 

 more orange and less golden than sorbi, Frey, and usually has the 

 posterior tarsi dark-spotted, whereas sorbi, almost invariably has them 

 unspotted. 



Though never previously recorded as British under this name, 

 Frey himself recognised oxyacanthce as such some years ago, for the 

 series in his collection includes five specimens sent him from England 

 by Stainton, who, in common with all other British authors, did not 

 allow that oxyacantha} was specifically distinct from the other species 

 confused by him under the name ''''pomifoliella.''''
