Haworth (Lep. Brit., Tin., 575) gives cydoniella as British on the 

 strength of its supposed occurrence, rarely, near Chelsea, and quotes 

 Fabricius' descriptions, but he probably applied the name incorrectly 

 to one, though, without seeing his specimens, it is impossible to say 

 to which, of our known British species. 



The following is an attempt to tabulate the nine species noticed 

 above : — 



1. Basal white streak wavy, remarkably long and slender 2 



Basal white streak straight, not remarkably long and slender 3 



2. Ground-colour rufous-orange = cerasicolella. 



Ground-colour greyish golden-ochreous = spinicolella. 



3. Basal white streak showing a strong tendency to unite with first dorsal tooth... 



= concomiteJla. 

 Basal white streak not showing a strong tendency to unite with first dorsal 

 tooth 4 



4. Hind tarsi often with dark spots 5 



Hind tarsi without dark spots = sorbi. 



5. Dorsal margin generally with a white line or spot near base 6 



Dorsal margin generally without a white line or spot near base 7 



6. Imago larger, reddish orange-golden in both sexes = hlancardella. 



Imago smaller, not reddish orange-golden in both sexes = oxyacanthcB. 



7. Imago larger and darker, particularly in the male sex = pyrivorella. 



Imago smaller and much lighter in both sexes 8 



S. Ground-colour conspicuously bright i-eddish-orange, white teeth broader 



^= ct/donieHa. 

 Ground-colour not so conspicuously bright reddish-orange, white teeth narrower 



= tnespilella.

SUPPLEMENTAEY NOTES. 



LiTHOCOLLETIS CEEASICOLELLA, H.-S. {cf. ante, pp. 243-4). 



Additional localities are Surrey (locally common, teste T. A. 

 Chapman). Scotland, Dumbartonshire (Bonhill, J. B. MalJoch). 



Meyrick, in HB. Br. Lep., 741, gives as a characteristic that the 

 black apical streak is edged above with white, and this holds good as 

 a rule, though exceptions can be found. 



It may be interesting to mention that I bred one abnormally 

 small specimen in which, on both fore-wings, the basal streak has 

 united with the first dorsal tooth, and the third and fourth costal 

 teeth have united together so as to form a large white spot.
