WITH DESCRIPTIONS OF NEW SPECIES, &C. 25 



insects in Britain. I allude to Curtis's paper in the " Philo- 

 sophical Transactions" for 1834, intituled " On some Non- 

 descript British Species of the May Flies of Anglers." 

 Dr. Leach's article on Entomology in the " Edinburgh 

 Encyclopedia" contained really the first contribution towards 

 furthering the study of the British Tricho'ptera ; but he 

 describes very few species. To Dr. Hagen great praise is 

 due, inasmuch as his papers in the '^ Annual" have revived 

 in this country a taste for the study of these insects, thus 

 rendering the publication of a Monograph of the British 

 species merely a question of time. 



The following species have not been included in the 

 Synopsis, and are described or noticed in their places iix 

 the remarks that follow. Those to which an asterisk is 

 affixed have not been previously described as occurring in 

 this country. I possess, or am acquainted with, specimens 

 of nearly as many more, but am at present unable to give 

 precise information respecting them. I fancy that my esti- 

 mate in the last "Annual," of 150 British species, will even- 

 tually prove to be under the mark.
