gender of the generic name, while others make the endings conform to 

 the gender of the genus, and although many eystematists with whom 

 1 have corresponded on this point strongly advise the recognition of the 

 gender in the termination of the specific name, I have decided to follow 

 the course adopted in nearly every list or catalogue of these insects which 

 I have seen from Linneus down, and make use of the simple termina- 

 tion — ana, leaving it for those who prefer the other course to change 

 the terminations given herein as follows: — The terminations of the 

 specific names under Lophoderus and Mellisopus, to the masculine 

 ending — anus, and those under Teras, Ptycholoma and Proteoteras, 

 to the neuter ending — anum. 



There are quite a number of species common to Europe and America, 

 and of these I have given the synonomy in part from the valuable 

 catalogue of the European fauna by Standinger and" Wocke, but the 

 greater part were verified by reference to the original works. The food 

 plants of these species were taken from Die Pflanzenfeinde aus der Klasse 

 der Insecten by Kaltenbaeh, Die Kleinschmetterlinge by August Hart- 

 niann. Die Lepidopteren der Schweiz by Prof. Frey, and the various 

 systematic works to which I have had reference. 



I have been much perplexed about the dates of some of the works 

 referred to, more particularly Hubner's Sammlung Europaescher Schinet- 

 terlinge. In Illiger's edition of the Systematische Verzeiehniss von den 

 Schmetterlingen der Wiener Gegend, on the next page after the Vorrede 

 of the first volume a short notice is given in which the statement is made 

 that the second volume is already in press. Although both of these 

 volumes are dated 1801 on their title pages, the Vorrede is followed 

 by the date Jan. 1798, and the notice above mentioned is dated 1800. 

 The second volume containing the Tortrices, has references to Hubner's 

 Sammlung, Tortrix, as far as plate 30, fig. 194. If the volume was in 

 press in 1800, the first 30 plates or 193 figures must have been issued 

 before that time, and we should give the date to these not later than 

 1800, (see also Ent. Mon. Mag. London, vol. vi, p. 140). I am quite 

 at a loss what precise date, if any. to give the remaining figures of 

 Hubner's Tortrix.
