LXV.—Notes on Dr. C. Flach’s Synonymic List of the 
European Trichopterygide. By the Rev. A. MATTHEWS. 
For the last few years the time which Ihave been able to devote 
to entomology has been fully occupied in investigating the 
Corylophidez ; but since that study has been almost finished, 
I have lately turned my attention to collecting materials fora 
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 Trichopterygide 
has been nearly doubled by the discovery of fresh species in 
various parts of the world, especially in America, through 
the exertions of Mr. Crotch, Mr. Champion, Dr. Le Conte, 
Dr. Horn, and Mr. Casey. 
Thus it has happened that until a few weeks ago I was 
unaware of the existence of an important essay on the Euro- 
pean species of Trichopterygide from the pen of Dr. C. Flach, 
published in the ‘ Verhandlungen der kaiserlich-kéniglichen 
zoologisch-botanischen Gesellschaft in Wien,’ vol. xxxix. 
1889, pp. 481-582. 
In this essay Dr. Flach has revised, or, rather, attempted
