This is a parasite of the Aphis of the poplar and willow, numbers 

 of which were found assembled at the base of the shoots of trees at 

 Kentish Town, by Dr. Knaggs, in the j)resent month. Aphidms salicis, 

 Hal., is found in the same situation, but is a different species ; see 

 Ent. Mag. ii, 102, and note. With A. grec/arius were several specimens 

 of another parasite. This is Ceraphron {Lij(jocerus) Carpenteri, Curtis. 

 I had often seen this species, but never traced its origin, though Curtis 

 says he bred it from ' female ' Aphides. Of course it attacks only 

 those Aphides which are already pierced by an Aphidius, having for its 

 object the larvae of the latter.

NOTES ON BRITISH TOR TRICES, WITH DESCEIPTIONS OP TWO 



NEW SPECIES. 



BT C. G. BARRETT. 



The publication of Drs. Staudinger and Wocke's Catalogue of 

 the Lepidoptera of the European District in 1871 caused such a re- 

 volution in the existing nomenclature, that a good deal of confusion 

 is likely to be caused in some groups by the indiscriminate use of two 

 sets of names. 



This is especially the case with the Tortrices, and as Mr. Wilkin- 

 son, in his ' British Tortrices,^ made no attempt to go into their 

 synonymy, I have thought that a few notes on changes of nomenclature, 

 with notices of uudescribed sj)ecies, and observations made since the 

 appearance of that work, may possess some interest, and perhaps con- 

 duce to a more thorough knowledge of our British species. 



In preparing these notes, I have constantly received most valuable 

 assistance from Mr. Stainton and Professor Zeller ; while Messrs. 

 Doubleday, McLachlan, Howard Vaughan, Machin, Birchall, and Sang, 

 Hev. Henry Burney, Dr. Buchanan "White, and other friends, have 

 liberally entrusted me with their rarest and most interesting species 

 for examination, and have given me much valuable information upon 

 them. 



As far as possible I jiurpose following the arrangement of Wilkin- 

 son's work, as it is more the basis upon which I must work than is 

 Doubleday's list. I am prevented from adopting the new arrange- 

 ment of Dr. Wocke by the difficulty I feel in adopting such a genus 

 as his Peiifhina, which, commencing with our Pcedisca profundana, 

 includes our Brachytainia, Pcnthina proj)er, Euchromia, Orthotcenia, 

 Jlixodid, lioxaiia, the larger species of Sericoris, and Sideria.
