the name deflexelJa, which Stainton, in ZooL, 1851, App. clxx, applied 

 to the spring brood in which this form of variation is frequent. 

 Steudel (/. c.) proposed the varietal name conjunctella for the form 

 ill which the first and second dorsal teeth unite to form an arch. 

 Vrey, in Tin. u. Pter. Schweiz, 3-41 (185G), and Snellen, in Tijd. v. 

 Eut , xi, 70 (1868), expressed doubts about cerasicolella and spinicolella 

 being specifically distinct, but these authors subsequently, the former 

 in Lep. Schweiz, 413—4 (1880), and the latter in Vliud. Ned. 

 Microlep., 928 — 5 (1882), treated both as valid species, which they 

 unquestionably are. 



Stainton, in a copy, which he sent to Zeller, of his " Monograph 

 of the British Argyromiges^'' published in Zool., 1848, pp. 2079 — 97, 

 2152 — 65, wrote, on p. 2092, with reference to his notice and figure 

 (PI. 2, fig. 15) of pomonella, " not pomonella but salicteUn.'" This 

 statement, made at a time when his ideas about these species were 

 being continually modified, is almost certainly erroneous. Salictella 

 is not known to have ever occurred in Britain, and it is almost incon- 

 ceivable that, as his Monograph dealt with British species only, the 

 description or figure of pomonella should have been made from a 

 species not occurring in Britain. Moreover, below the description he 

 says " I took this species in plenty last May on the Penge palings," so 

 most probably both the description and figure were made from Penge 

 specimens, and they agree well with sjyinicolella, 7a.
