 flies is usually one year from egg to imago, and this 

 has been fully verified from the life-history specimens 

 of the Welshman's button presented to the Fly- Fishers' 

 Club by Mr. Arthur N. Gilbey, as stated in a previous 

 page. Mr. Mosely has also confirmed this in the case 

 of Notidobia ciliaris. 



The type of the largest of the Trichoptera, the

 streams and other rivers, I have selected three types 

 of colouration and size only. I am quite conscious of

 Synopsis of the Trichoptera of the European Fauna," 

 published 1 874-1 880, it will be seen that he there 

 computed the total number of species (then existing 

 in collections) as between 250 and 300, and he fore- 

 shadows a considerable increase in these numbers. 

 Some years since Rev. A. E. Eaton examined a few 

 specimens from the Test, and found twenty-three 

 different species ; and Mr. Mosely, who has for some
