APPENDIX 



TO 



THE ZOOLOGIST 



FOR 1849. 



With a view of giving to Monographs and other papers of a scien- 

 tific and technical character that prominence which all careful and 

 elaborate productions deserve, and at the same time of avoiding all 

 clashing between such papers and the more amusing details of the 

 economy of living animals and the record of captures, — I have con- 

 cluded in the present Volume to separate the popular from the scien- 

 tific communications, and to publish the latter with a different 

 heading and paging in the form of an Appendix. — E. Newman. 



Art. I. — A Monograph on the European Species of the Genus Argijresthia. 

 By H. T. Stainton, Esq. 



I will first say a few words as to my reason in here departing from my previous 

 plan of only describing the British species : in the first place, I have not the slightest 

 doubt that all the species here described occur in this country ; and secondly, by giving 

 the distinguishing characters of each, as well as their habits (where known) and period 

 of flight, I surely am conferring a great boon upon the provincial collectors of 

 Micro-Lepidoptera, who have not the same means of access to continental works or 

 continental specimens which metropolitan entomologists enjoy. Many species only 

 require to be looked for in order to be taken, and as long as we are ignorant of the 

 species and their habits we do but retard the period of their discovery. 



I shall not give a detailed account of the generic characters : not having examined 

 the insects with a microscope, I do not feel qualified to enter into any of the minute 

 distinctive characters. Zeller has occupied three pages in the ' Linnaea Entomolo- 

 gica ' (vol. ii. pp. 236 — 239) with this portion of the subject, and to his valuable paper 

 I must refer such of my readers as feel curious on the matter. 



The following superficial characters may perhaps prove of some use : — Head 

 clothed with erect hairs ; face smooth ; palpi drooping ; antennae (shorter than the an- 

 terior wings) with the basal joint enlarged ; anterior wings long and narrow ; posterior
