NOTES ON SOME HYDROPSYCHID^E 
By Nathan Banks 
Mr. Milne’s third part of his Studies of Trichoptera hav- 
ing appeared and finishing the series, I offer certain re- 
marks thereon, particularly on some Hydropsychidse. Some- 
what similar criticisms can be made of various other parts. 
Mr. Milne has on several occasions credited me with placing 
a name as a synonym when it was first done by others. 
Thus under Hy dropsy che alternans Walk, he puts H. 
morosa Bks. (nec. Hag.) as synonym. Now four years be- 
fore I was born Hagen himself in his Phryganidarum Sy- 
nopsis Synonomyica, p. 25, 1864, puts his H. morosa as 
equal to alternans Walk. McLachlan had indicated it the 
year before. Both I and Ulmer have simply accepted the 
dictum of Hagen and McLachlan. 
In the type series of H. morosa now in the Museum there 
are five specimens of alternans and three of a Cheumato- 
psyche from Red River of the North. These three do not 
agree well with the description, but Milne has taken them 
to bear the name morosa. Therefore to keep the name 
morosa as Hagen, Ulmer, and I have kept it for seventy 
years, I have selected and marked as lectotpye of Hydro- 
psyche morosa Hagen a male from “St. Lorenz, Canada, 
Sacken 1859,” which is what has been commonly called 
alternans Walk. The three Cheumatopsyche from Red 
River are near to some of Hagen’s types of H. phalerata. 
But since Ulmer has figured 1 (Selys Monographs fasc. VI, 
p. 66, 1907) a species of Hydropsyche as Hagen’s H. phale- 
rata (and some of Hagen’s types were of this form) I have 
selected and marked as lectotype Hydropsyche phalerata 
Hagen a specimen from “Washington, Sacken,” which is 
the species figured by Ulmer. This is much smaller than 
1 His dorsal figure shows apical joint of claspers too long.
