these difierenccs are now so pei'rnanently fixed, that the treatment of 

 pyrivorella as specifically distinct seems to me not only justifiable, but 

 clearly expedient.

Larva— m a short mine on under-side of leaves of Pyrus aria, 

 aucitparia, torminalis, and cydonia. vii, ix — x. Frey (Lep. Schweiz, 

 414) adds ^'■Amelanchier " and " Cotoneaster,'^ and by sleeving out 

 a pair of moths, bred from P. aiicuparia, on a cultivated pear-tree, 

 I reared a brood from it. In Ent. Ann., 1862, p. 139, mespilella 

 is recorded, under the name " forw?meZZ«," as having been bred by 

 Mr. McLachlau from larv?e found mining IMorella cherry leaves at 

 Exeter, and Lord Walsingham and Mr. Durrant, who have seen one 

 of the bred specimens, agree that it is mespilella. 



Pupa — vii — viii, x~ iv. I have no note as to whether the cocoon 

 is distinct or the reverse. Sorhagen (I. c.) describes the pupa as 

 " without a cocoon," Corbett (Ent. Eec, x, 169), as "with a cocoon." 



Lmayo — iv — v, vii — viii. 



Broods— iyio. Hibernates as pupa. 



Hah. — England, Devon (Exeter, E. McLaclilan), Dorset (I. of 

 Purbeck, G. P. Dighy, E. B. Bankes), Gloucestershire (Bristol, teste 

 H. T. Stainton), Herefordshire (Tarrington, J. H. Wood), Kent 

 (Lewisham, B. A. Boiver, IT. T. Stainton), Lancashire (Manchester, 

 teste H. T. Stainton). Centeal Europe. 



Imago. — Fore-wings rich reddish-orange in both sexes, though the males 

 naturally tend to be a little darker than the females ; basal white streak of moderate 

 length and breadth, rarely showing any tendency to unite with the first dorsal tooth.
