LXV. — Notes on Dr. C. Flaclis Synonymic List of the 

 European Trichopterygidse. By the Rev. A. Matthews. 



For the last few years the time which I have been able to devote 

 to entomology has been fully occupied in investigating the 

 Corylophidai ; but since that study has been almost finished, 

 I have lately turned my attention to collecting materials for a 

 second part of my * Trichopterygia Illustrata,'' and I find 

 that such a work is much needed, for, since the publication 

 of the first part in 1872, the number of the Trichoptcrygidie 

 has been nearly doubled by the discovery of fresh species in 

 various parts of the world, esi)ecially in America, through 

 the exertions of Mr. Crotch, Mr. Champion, Dr. Le Conte, 

 Dr. Horn, and Mr. Casey.
