226 BRITISH LEPIDOPTERA. 



Time of appearance. — This species is only recorded as being 

 single-brooded, but the experience of Threlfall (vide below) goes to show 

 that it is donble-brooded. Frey obtained imagines in May, 1858, from 

 larvae found on October 25th, 1857, and Heyden, in the beginning of 

 May, 1859, from larvae found in the middle of October, 1858. Hodgkin- 

 son bred imagines on April 15th, 1877, from larvae found the preceding 

 autumn at Witherslack. Threlfall found larvae at Grange on October 

 5th, 1878, and bred the imagines freely from May 5th-12th, 1879. 

 From larvae obtained July 21st, 1877, at Witherslack, he also bred 

 imagines plentifully on August 17th of the same year. Fletcher 

 discovered mines, at Abbott's Wood, on November 11th, 1888. 

 Cambridge gathered larvae in their mines as late as November, 

 1889. Sang's dates are October 17th, 1871, October 24th, 1873, 

 July 16th and September 30th, 1874, September 24th, 1880, at 

 Darlington ; October 18th, 1878, at Castle Eden (teste Gardner).- 

 Nolcken records finding young larvae on September 22nd, 1865, at 

 Pichtendahl. He captured imagines on May 9th, 1866, at Sail, and 

 on May 18th, at Pichtendahl.

References to N. tormentillella as a British species. — This 

 species appears to have been introduced and re-introduced into the 

 British list without any real reason. The references are as follows : 

 (1) Stainton notes (Ent. Weekly Int., viii., p. 168) that Herrich-Scbiifi'er 

 had described N. tormentillella and other new species. He adds : " X. 

 tormentillella is a widely distributed species, as we have found it at
